Cell Transport
Passive transport
Diffusion
Is when molecules move in a fluid or gas, that has a higher concentration to a region that has a lower concentration. This causes molecules to collide and scatter. This is important because it helps move different substances across the membrane, it also helps the cells diffuse the oxygen without expending energy.
Osmosis
It is when molecules move around the membrane through a semipermeable part, from a part that has a higher concentration of water to a lower concentration of water.
Explanation Process
Passive transport is the opposite of active transport. Molecules or ions move from higher areas of concentration to areas that have a lower one. Usually they move to the places that have few molecules.
Definition
It is when ions or molecules move from a higher are of concentration to an area that has a lower one.This process does not require metabolic energy.
Active transport
Definition
It is when ions or molecules are transported through the cell membrane, to the region of higher concentration. This process requires enzymes.
Explanation Process
For active transport to work, it needs metabolic energy, so they spend this energy to move the molecules or ions around. They are moved to the area that has a higher concentration, so as to keep cells alive.

Exocytosis
Is the process of releasing a substance out of a cell by merging with the cell membrane through a vesicle. After this, the vesicles create themselves around materials, so that they can be sent out of the cell. Then, the vesicle unite with the cell membrane of the cell, and it fusions with one another, so the content can be released.
Endocytosis
Is the process of gaining liquids or large molecules. This process immerses them into the membrane. After this, the cell membrane creates a pocket, that then explodes, so that the molecules will unite with a lysosome or a vescile similar to them. The lysosomal enzymes then break down and the content of this is released into the cell.
