Cell theory & the cell membrane Flashcards
the cell membrane separates the cell cytoplasm from its surroundings and controls the exchange of materials, including nutrients and wastes
cells are the structural unit of living things
every cell comes from a previous cell that contains hereditary information
respond to stimuli
reproduce themselves
grow and develop
viruses dont reproduce themselves & grow
what are the cell membranes functions
-Making a clear separation between the inter and extracellular environment
- it decides what gets transported in and outside of the cell.
-Enables cells to recognise each other
The cell membrane is a fluid mosaic model, which is fluid as phospholipids are constantly moving fluidly, and is a mosaic as proteins are embedded throughout the membrane.
what is the structure of the cell membrane
The cell membrane is made up of a phospholipid bilayer. which forms a stable barrier between two aqueous compartments.
