The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection. Plant cells have some specialized properties that make them distinct from animal cells.

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 ...

Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.

This sophisticated membrane structure allowed for the complexity of life as we know it. But how did the earliest, simplest cells hold it all together before elaborate membrane structures evolved?

Membrane-bound organelles were the textbook standard of how scientists thought cells were organized until they realized ...
