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 order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier ... Eukaryotic cells use three major processes to transform the ...

Cell membrane Allows gases and water to diffuse freely into and out of the cell. Controls the transport of other molecules. Mitochondrion (plural is mitochondria) Contains enzymes for the ...

Nature has developed a unique structure as a scaffold for almost all nerve cells: the membrane-associated periodic skeleton ...

"This work challenges a major assumption of cell biology by showing that the plasma membrane, the flexible bilayer that surrounds the cell, can have drastically different phospholipid abundances ...

All cytoskeletons consist of three major classes ... the nuclear membrane. Note that intermediate filaments are not polar in the way that actin or tubulin are (Figure 4). Other cell movements ...
