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 ...

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.

Cells have a mailing system of sorts. They can release tiny molecular balls, called extracellular vesicles (EVs), that ...

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.

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

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

Aquaporins are proteins that rapidly transport water across cell membranes while excluding ... organized into a helix structure called polymers, or into cyclic structures called macrocycles.

Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Plants feel firm because of their cellular walls.

Researchers have discovered that a key bacterial protein, CsrA, gathers in a droplet-like structure inside cells to control ...
