Both types of membranes have a specialized structure that facilitates their gatekeeping function ... Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic ...

A key experiment using the Langmuir trough provided the basis for accepting that the membrane is a bilayer and laid the groundwork for the current model of membrane structure. First, cells are ...

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.

Northwestern University researchers have identified structural features in engineered cell receptors that correlate with ...
