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.
