The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.
the cell membrane is not completely permeable.This allows substances in and out of the cell and only a few substances could get into the cell.If the cell membrane becomes permeable any substance including the bad ones will get in easily this could destroy the cell.
Substances pass through the plasma membrane, although ot is not technically an organelle.
Examples of substances that enter the body include nutrients from food, oxygen from the air we breathe, and medications. Substances that leave the body include carbon dioxide when we exhale, waste products such as urine and sweat, and toxins removed by the liver.
by melting
Substances in granite can enter magma through a process called assimilation. When magma intrudes into pre-existing rock like granite, it can incorporate elements and minerals from the surrounding rock into the melt, altering its composition. This can happen through melting and assimilation of parts of the granite or through the mixing of magma with granite-derived fluids.
Diffusion is the methods that leave cells. Diffusion also has to have cellular energy.
By crystalization! B***H
The substances that enter into a reaction are called reactants.
"reactants"
You could be referring to the cell membrane or carrier proteins. Both allow certain substances to enter cells.
