Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

This takes place when molecules diffuse across the cell membrane by travelling through ... by the breakdown of ATP inside the cell. This diagram shows molecules moving from area of low ...

The diagram below shows the same plant cell ... used in chemical reactions such as photosynthesis and respiration. Cell membrane Allows gases and water to diffuse freely into and out of the ...

In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house ...
