allows for appropriate reactions to take place as it keeps the conditions right for
each reaction.
The cell surface contains phospholipids and proteins. The lipids give the cell its
flexibility and firmness also maintaining its shape. The lipid layer presence can
vary between 2080% with the rest being proteins.…read more

2. Secondly we

which are the
cell's lungs. The
term simply means
"thread granule"
when translated
from French. They
are the energy
providers inside
the cell. The
energy is released
when the
respire using oxygen. This chemical adenosine triphosphate (ATP) transports
the energy which is required for all cells in order to function. It is the main
source of energy in cells.…read more

arranged in a 9 + 3 pattern as a ring of nine microtubules arranges in "triplets" at
90°angle to each other.
During mitosis each centriole moves to the opposite end of the cell. Then, they
being to pull apart the cell arranging the chromosomes using a spindle of fibres
that the microtubules form. This process doesn't happen in plant cells as they
don't have centrioles.…read more

and proteins can be found in the nucleolus as well. The nucleolus's main function is to
make ribosomes which are a crucial organelle during protein synthesis.
The nucleolus has a similar shape to the nucleus and can sometimes in large cells take
up to 25% of the nucleus also being extra dense. Sometimes, a nucleus can contain up
to four nucleoli. The nucleolus is often identified as the "dark spot" in the nucleus.…read more
