the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny‚ three dimensional sac which is in fact made up of many components‚ each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own‚ individual function which helps a cell to function and maintains the cell membrane. The components that

Biology 1 1st October 2011 Animal Cells Every once living thing is composed of cells. Cells are small organisms that control everything in living things. When an organism is made of one or more cells it is called a multi cellular organism. The first person to discover cells was Richard Hooke. The cells that he saw were the dead cells of cork. When he first saw them they reminded him of the cells that nearby monks lived in. there are many different parts of the cell but all serve a purpose. These

Estimating Osmolarity of Plant Cells Criteria Assessed: DCP Introduction In this experiment you will be estimating the osmolarity of potato cells by finding their change in weight in solutions of known molarity. The object is to find the molarity where the mass does not change. No net change in weight indicates that there has been no net gain or loss of water. This is a means of indirectly finding the osmolarity of the cells themselves. Apparatus 1 large potato Petri dish 7 x 250 ml beakers

An animal cell is not visible to the naked eye and is about 10 to 30 micrometers. A micrometer is one one-thousandth of a millimeter. They are so small that it takes a microscope with a magnification of at least 400x to be able to see inside the cell. These cells are what make up the basic units of structure and function in all living things. They carry out our life processes and make it possible for us to function and live. Inside these cells are organelles‚ which are smaller than the cell itself

The difference between bacteria‚ viruses‚ fungi and parasites are: Bacteria are single celled organisms that can rapidly multiple themselves every 10 minutes up to 10 times each bacterial cell‚ but they do not live or reproduce in a human cell. When threatened they will make a copy of their DNA to enable them to come back to life in the right conditions. They are able to survive in most extreme living conditions including with and without oxygen‚ there are various types of bacteria such as Cocci/Coccus

Cell division in animals: mitosis‚ cytokinesis‚ and the cell cycle. Cell division in animals is a two-step process involving mitosis and cytokinesis and is set up by interphase. Interphase is a growth period for the cell. In the nucleus the chromosomes are duplicated but are not yet distinguishable because they are still a form of chromatin. There is also a nucleoli‚ one or more‚ present producing ribosomes that are sent to the cytoplasm. Mitosis is the division of the nucleus and multiplication

Our ancestors lived in harsh environments in the Savanna Desert and struggled to stay alive. Over time‚ our ancestors started settling down‚ eventually they came up with little ways to make their life easier. The domestication of plants and animals changed human life in a good and big way because more food was produced‚ trades were established‚ jobs were specialized‚ and people were able to settle in villages. Firstly‚ people produced more foods which lead to many new things. They had surpluses

I couldnt believe it. I had no clue on what I had got myself into. I thought I was in a nightmare. Everything was so much larger than me. I felt like I was this tiny spec on a flower. My life had suddenly flashed before my eyes. I had a feeling that my last breath was about to par take. I knew that I should have never drunk that stuff that my friend gave me. She said that it would take me to another world‚ but I didnt take her seriously. I thought it was just her joshing around. How could a normal
