ANIMAL CELLS

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.
