At physiological temperatures, cell membranes are fluid; at cooler temperatures, they become gel-like. Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic ...

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.

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on ...

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 specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

New research, published recently in Proceedings of the National Academy of Sciences, uncovers the unique dynamics governing ...

But understanding the structure and interactions of cholesterol ... implications for understanding diseases related to cell membrane function, particularly cancer, where membrane organization ...
