Unit 6: Membranes and transport About this unit This unit is part of the Biology archive. Browse videos and articles by topic. For our most up-to-date, mastery-enabled courses, check out …

If a molecule wanted to diffuse across the plasma membrane, but wasn't able to make it all the way through, what would happen to it? Would it eventually work its way in, or would it get …

The fluid mosaic model explains the structure of cell membranes. These membranes are composed of phospholipids, forming a bilayer with hydrophilic heads facing outwards and …

Explore the structure and functions of plasma membrane and cytoplasm, essential components of cells that regulate material exchange and provide structural support.

The plasma membrane’s selective permeability is essential for maintaining cellular homeostasis: it allows the membrane to maintain a distinct internal environment for the cell, and also regulates …

A plasma membrane is a layer around a cell that prevents the cytoplasm from getting all mixed up with the outside environment. Plasma membrane (cell membrane) is made of two phospholipid …
