Animal Cells Essay, Research Paper


ANIMAL CELLS My cell is the animal cell It really depends on which cell you are talking about – different cells

do different things. Such as skin cells. They form a barrier on the outside of the body which protects the organs

and tissues inside. It stops them getting damaged by bumps and knocks and also prevents bacteria and viruses

from getting into your body. The cells structure, contains the Cell Membrane keeping the cell together and

controlling what substances go in and out, Cytoplasm is the water-rich matrix within a cell that contains and

surrounds the other cell contents. Nucleolus is a small region that is made up of RNA and protiens,it also

produces ribosomes. Mitochondria burns food molecules to release energy. This energy is used by cells to do

work. This work may be building new molecules which have a particular function in the body, or it may be to

produce movement. Ribosomes are often attached along the length of the ER. These manufacture proteins which

pass into the inner part of the tube they might have sugars of fats added and they fold up into the shape they need

to be to carry out their function. Rough and Smoth ER. is the sythesis of proteins or transportation materials

through the cell Rough ER is rought because ribosomes are stuck to its surface which gies it a rough apperance.

New protiens are inserted into the rougth ER there they may be chenimcaly modified. the Smooth ER are sacks

that look smooth and are not studded in which chemicals and enzymes are stored.Goli Apparatus modifies and

collects and distributes molecules made at one end of the cell and used in another. Lysosomes are bags of

destructive enzymes which are produced by the cell to break down complex molecules. Vacuoles are sack that

store water,salts, proteins and carbohydrates.Centriole is a structure that comains microtubule protein called

tubulin.cytoskeloten is a web of fibres which provide a sort of scaffolding for the cell, keepings its shape and

supporting the organelles which are inside. Cell Wall help protect the the cell from what is outside of the cell and

also supports the cell. I hoped you learned alot about the animal cell I enjoyed learning about it and wish that I

could of spent more time on the project and it is also amazing that we started life being no bigger than a period

on this report. And that how important cells are to our life.
