NEPHRON ESSAY
Essay Question: Write a short essay explaining the homeostatic functioning of the nephron if a person is suffering from dehydration
Life Sciences essays for Grade 10, 11 and 12
When the water content of the body drops below normal, the following happens
- the osmotic potential of the blood increases √
- which stimulates the osmoreceptors in the hypothalamus √
- which produces ADH
- to transmit impulses to the pituitary gland (hypophysis) √
- to release more ADH √ in to the blood
- ADH is transported by bloodstream to the kidney √ where this hormone increases the permeability √ of the walls of the distal convoluted tubule and collecting duct √
- more water √ is re-absorbed from the filtrate √
- and small amount of concentrated urine √ is excreted
- the adrenal gland √ secrete aldosterone √ which cause sodium ions √ to be actively √ pumped out of the filtrate √ in the ascending limb of loop of Henle √ in to the tissue fluid of the kidney medulla √
- this creates a low water potential √ and water moves by passive osmosis √ from the collecting tubule √ in to the tissue fluid of the medulla √ from where it is absorbed in to the blood capillaries √
ECOUTOURISM ESSAY
Essay Question: Write a mini essay on ecotourism in South Africa using the following guideline
- Brief explanation of what ecotourism entails,
- Long term sustainability and Possible threat to Ecotourism
- Ecotourism is mainly inclined to promote environmental awareness and instil asense of appreciation of natural formations and beauty.
- It makes people respect the existence of other living organisms (fauna and flora) that shares the resources of the planet earth
- Its main clients are people who are interested in preserving the environment.
- A potential ecotourist prefers to spend his/her holidays in a natural environment to experience and be part of the environment
- They like to visit and spend time in quiet natural settings such as unspoiled beaches, river mouths, waterfalls, wet lands with lush green forests, gorges,mountains etc.
- Always prefer to use eco-friendly mode of transport to cause less pollution and damage to fauna and flora
- Encourages people to consume naturally grown, fresh produce from the area
- Greater emphasis is placed on the well-being of local people and constantly look for ways and means to contribute towards the local economy
- Eco-friendly accommodation is provided for visitors to minimise the possible human impact on the surrounding area
- Renewable energy is utilised wherever possible
Long term sustainability
Educate the local population about the importance of conserving the natural resources.
- The involvement of the local community should be prioritised.•
- Active participation generates income for local communities. e.g. selling composts, organic food products.
- Job creation alleviates poverty. e.g. tour guides, security personnel, and creating opportunities to sell and exhibit art work.
- Ownership of the concept leads to proper caring and protection of the fauna and flora. e.g. prevention of poaching, illegal smuggling of exotic animals and plants, discourages over exploitation of natural resources.
- Part of the income generated can be utilised for conservation and rehabilitation projects.
- Cementing strong partnership with the private and public sector could provide more management and financial support
Possible threats to ecotourism
- Poaching / illegal hunting
- Crime and violence against tourists
- Illegal trade of exotic plants and animals
- Illegal occupation of land and the establishment of squatter camps
- Natural disasters. e.g. wild fires, droughts, floods, etc.
- Deforestation• Extension of farming lands
- Illegal dumping of waste
- Illegal developments e.g. hotels and golf estates, airports, stadia. etc.
- Building of dams in an ecologically sensitive area
- Miningo Exploitation of tourists

Life Sciences have always been a fundamental area of science. The exponential increase in the quantity of scientific information and the rate, at which new discoveries are made, require very elaborate, interdisciplinary and up-to-date information and their understanding. This fourth edition of Life sciences, Fundamentals and practice includes extensive revisions of the previous edition. We have attempted to provide an extraordinarily large amount of information from the enormous and ever-growing field in an easily retrievable form. It is written in clear and concise language to enhance self-motivation and strategic learning skill of the students and empowering them with a mechanism to measure and analyze their abilities and the confidence of winning. We have given equal importance to text and illustrations. The fourth edition has a number of new figures to enhance understanding. At the same time, we avoid excess detail, which can obscure the main point of the figure. We have retained the design elements that have evolved through the previous editions to make the book easier to read. Sincere efforts have been made to support textual clarifications and explanations with the help of flow charts, figures and tables to make learning easy and convincing. The chapters have been supplemented with self-tests and questions so as to check one’s own level of understanding. Although the chapters of this book can be read independently of one another, they are arranged in a logical sequence. Each page is carefully laid out to place related text, figures and tables near one another, minimizing the need for page turning while reading a topic. I have given equal importance to text and illustrations as well. We hope you will find this book interesting, relevant and challenging.

We think you are located in Russian Federation . Is this correct?
We use this information to present the correct curriculum and to personalise content to better meet the needs of our users. 2.3 Cell structure and function2.3 Cell structure and function (ESG4S)Section 3: Cell Structure and Function In this section the learners now expand their knowledge and learn the various cell structures and related functions. The roles of the organelles within the cells need to be introduced and relate structure and location of organelles to their function. Cells differ in size, shape and structure and therefore carry out specialised functions. Link this to tissues. The differences between plant and animal cells can be linked to Grade 9. Cell theory (ESG4T)The cell theory developed in 1839 by microbiologists Schleiden and Schwann describes the properties of cells. It is an explanation of the relationship between cells and living things. The theory states that:
The cell theory applies to all living things, however big or small. The modern understanding of cell theory extends the concepts of the original cell theory to include the following:
DNA (the hereditary information of cells) is passed from 'parent' cells to 'daughter' cells during cell division. You will learn more about this in the following chapter: Cell division . Cells are the smallest form of life; the functional and structural units of all living things. Your body contains several billion cells, organised into over 200 major types, with hundreds of cell-specific functions. Some functions performed by cells are so vital to the existence of life that all cells perform them (e.g. cellular respiration). Others are highly specialised (e.g. photosynthesis). Figure 2.9 shows a two-dimensional drawing of an animal cell. The diagram shows the structures visible within a cell at high magnification. The structures form the ultrastructure of the cell. Figure 2.9: Diagram of the cell ultrastructure of an animal cell. The cell wall is a rigid non-living layer that is found outside the cell membrane and surrounds the cell. Plants, bacteria and fungi all have cell walls. In plants, the wall is comprised of cellulose. It consists of three layers that help support the plant. These layers include the middle lamella, the primary cell wall and the secondary cell wall. Middle lamella : Separates one cell from another. It is a thin membranous layer on the outside of the cell and is made of a sticky substance called pectin. Primary cell wall : Is on the inside of the middle lamella and is mainly composed of cellulose. Secondary cell wall : Lies alongside the cell membrane. It is is made up of a thick and tough layer of cellulose which is held together by a hard, waterproof substance called lignin. It is only found in cells which provide mechanical support in plants. The human body cannot break down the cellulose in cell walls because we do not produce the enzyme cellulase. Figure 2.10: Scanning electron microscope micrographs of diatoms showing the external appearances of the cell wall. Scale bar: A, B, D: 10 um, C 20 um Functions of the cell wall
Cell membrane (ESG4W)The cell membrane , also called the plasma membrane, physically separates the intracellular space (inside the cell) from the extracellular environment (outside the cell). All plant and animal cells have cell membranes. The cell membrane surrounds and protects the cytoplasm . Cytoplasm is part of the protoplasm and is the living component of the cell. The cell membrane is composed of a double layer (bilayer) of special lipids (fats) called phospholipids . Phospholipids consist of a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophobic head of the phospholipid is polar (charged) and can therefore dissolve in water. The hydrophobic tail is non-polar (uncharged), and cannot dissolve in water. The lipid bilayer forms spontaneously due to the properties of the phospholipid molecules. In an aqueous environment, the polar heads try to form hydrogen bonds with the water, while the non-polar tails try to escape from the water. The problem is solved by the formation of a bilayer because the hydrophilic heads can point outwards and from hydrogen bonds with water, and the hydrophobic tails point towards one another and are 'protected' from the water molecules ( Figure 2.11 . Figure 2.11: The lipid bilayer showing the arrangement of phospholipids, containing hydrophilic, polar heads and hydrophobic, non-polar tails. Recall the structure of lipid molecules from the previous chapter on the chemistry of life . All the exchanges between the cell and its environment have to pass through the cell membrane. The cell membrane is selectively permeable to ions (e.g. hydrogen, sodium), small molecules (oxygen, carbon dioxide) and larger molecules (glucose and amino acids) and controls the movement of substances in and out of the cells. The cell membrane performs many important functions within the cell such as osmosis, diffusion, transport of nutrients into the cell, processes of ingestion and secretion. The cell membrane is strong enough to provide the cell with mechanical support and flexible enough to allow cells to grow and move. Watch a video about the cell membrane. Video: 2CPB Structure of the cell membrane: the fluid mosaic model S.J. Singer and G.L. Nicolson proposed the Fluid Mosaic Model of the cell membrane in 1972. This model describes the structure of the cell membrane as a fluid structure with various protein and carbohydrate components diffusing freely across the membrane. The structure and function of each component of the membrane is provided in the table below. Table 2.2 refers to the components of the cell membrane shown in the diagram in Figures Figure 2.11 and Figure 2.12 . Figure 2.12: Fluid mosaic model of the cell membrane.
A further description of the fluid mosaic model can be viewed at: Video: 2CPC Movement across membranes (ESG4X)Movement of substances across cell membranes is necessary as it allows cells to acquire oxygen and nutrients, excrete waste products and control the concentration of required substances in the cell (e.g oxygen, water, hormones, ions, etc). The key processes through which such movement occurs include diffusion, osmosis, facilitated diffusion and active transport. Learn about the different ways that molecules can travel across cell membranes. Video: 2CPD 1. Diffusion Diffusion is the movement of substances from a region of high concentration to low concentration. It is therefore said to occur down a concentration gradient . The diagram below shows the movement of dissolved particles within a liquid until eventually becoming randomly distributed. Diffusion is a passive process which means it does not require any energy input. It can occur across a living or non-living membrane and can occur in a liquid or gas medium. Due to the fact that diffusion occurs across a concentration gradient it can result in the movement of substances into or out of the cell. Examples of substances moved by diffusion include carbon dioxide, oxygen, water and other small molecules that are able to dissolve within the lipid bilayer. Watch diffusion taking place by clicking on the following link. Video: 2CPF Observing diffusionTo observe diffusion.
Observing Diffusion
When the concentration of solutes in solution is low, the water concentration is high, and we say there is a high water potential . Osmosis is the movement of water from a region of higher water potential to a region of lower water potential across a semi-permeable membrane that separates the two regions. Movement of water always occurs down a concentration gradient, i.e from higher water potential (dilute solution) to lower potential (concentrated solution). Osmosis is a passive process and does not require any input of energy. Cell membranes allow molecules of water to pass through, but they do not allow molecules of most dissolved substances, e.g. salt and sugar, to pass through. As water enters the cell via osmosis, it creates a pressure known as osmotic pressure. Watch osmosis taking place by clicking on the following link. Video: 2CPG In biological systems, osmosis is vital to plant and animal cell survival. Figure 2.15 demonstrates how osmosis affects red blood cells when they are placed in three different solutions with different concentrations.
Plant cells use osmosis to absorb water from the soil and transport it to the leaves. Osmosis in the kidneys keeps the water and salt levels in the body and blood at the correct levels. Predicting the direction of osmosis To predict the direction of osmosis.
Watch an illustration of diffusion and osmosis. Video: 2CPH 3. Facilitated diffusion Facilitated diffusion is a special form of diffusion which allows rapid exchange of specific substances. Particles are taken up by carrier proteins which change their shape as a result. The change in shape causes the particles to be released on the other side of the membrane. Facilitated diffusion can only occur across living, biological membranes which contain the carrier proteins. A substance is transported via a carrier protein from a region of high concentration to a region of low concentration until it is randomly distributed. Therefore movement is down a concentration gradient . Examples of substances moved via facilitated diffusion include all polar molecules such as glucose or amino acids. 4. Active transport Active transport is the movement of substances against a concentration gradient, from a region of low concentration to high concentration using an input of energy. In biological systems, the form in which this energy occurs is adenosine triphosphate (ATP) . The process transports substances through a membrane protein. The movement of substances is selective via the carrier proteins and can occur into or out of the cell. ATP and ADP are molecules involved with moving energy within cells. You do not need to know these names in full and will learn more about them later. Examples of substances moved include sodium and potassium ions as shown in Figure 2.18 Life Sciences Grade 10 Latest Essays and Topics Guide CAPS: Education ResourceLife Sciences Grade 10 Latest Essays and Topics Guide for CAPS Curriculum (Syllabus) South Africa: A National Curriculum and Assessment Policy Statement (CAPS) is a single, comprehensive, and concise policy document introduced by the Department of Basic Education for all the subjects listed in the National Curriculum Statement for Grades R – 12.
