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.

In animal cells, movement of membrane into an endocytic ... Previous models of membrane structure have depicted adhesion as discrete membrane protein–cytoskeleton bonds that are discontinuously ...

The structure and function of key prokaryotic cell structures. Prokaryotes have ribosomes but they are smaller and structurally simpler than those in eukaryotic cells. These non-membrane-bound ...

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 ...

Filopodia are composed of hexagonal bundles of proteins that give them structure and strength ... These bundles are then encased in long membrane tubes to form filopodia, which must be strong enough ...

Filopodia are composed of hexagonal bundles of proteins that give them structure ... in long membrane tubes to form filopodia, which must be strong enough to protrude beyond the cell and yet ...
