Newtons first law of motion have a very nice day
That execution outside of the cell in which it is produced
is Enzymes it degrade large molecules into units that are little enough to be
pass through across the cell membrane and into the cell where they can be very
useful.
The plasma membrane or the cell
membrane is the one that protects the cytoplasm of a cell. It is mostly
composed of lipids and proteins. It has a phospholipid bilayer that controls
the entering and exiting of molecules in the cell and at the same time,
provides protection for the cell or plasma membrane. It has polar head and a
nonpolar tail. Proteins embedded within the phospholipid bilayer have the same
function of the plasma membrane that includes selective transport. The
phospholipid bilayer consists mainly of the lipid molecules.
the Nucleus
Explanation:
Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
Not sure if I'm correct but my best guess is the cell membrane seeing as it surrounds the cell itself and is responsible for allowing certain molecules to diffuse in or out of the cell. Good Luck! :)
