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.

The electron microscope reveals the structure of this gossamer layer, which not only constitutes the exterior of the cell but also folds inward to make up much of its internal architecture ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

This section describes three biochemical processes that alter the structure of the fatty acids ... would disrupt the architecture of the cell membrane and these products must be either eliminated ...

Lipids, or fats, are essential to life. They form the membranes around cells, protecting them from the outside. In nature, ...

Membraneless organelles, also called biomolecular condensates, are changing how scientists think about protein chemistry, ...

GC-A's elongated structure and relatively thin anchoring in the cell membrane make it "floppy," with a shape that is difficult to capture. It usually has a different conformation in each cryo-EM ...

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, ...
