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 ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows.

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.

Scientists apply principles of math and physics to unravel the mystery of how the endoplasmic reticulum, an organelle vital ...

Benzodiazepines like Valium and Xanax are often prescribed to treat anxiety, insomnia and seizures. While these drugs can be ...

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.
