The statements that are true about cell membrane are:
- In water, phospholipids spontaneously arrange into a bilayer.
- Steroids in cell membranes allow the membrane to be more fluid.
- Phospholipid bilayers surround all eukaryotic cells.
- Both plant and animal cell membranes are considered fluid mosaics.
A biological barrier called the cell membrane isolates and safeguards the interior of all cells from the external environment. Cells make up all living things, including both eukaryotic and eukaryotic creatures, and all cells have cell membranes.
Phospholipids naturally form bilayers in an aqueous environment, with the hydrophilic heads of the phospholipids facing the water environment at the surface and the hydrophobic fatty acid chains being protected from the water on the inside. Steroids are lipids that intercalate into the plasma membrane's bilayer of a cell, making the cell membrane less fluid. Different biological functions for integral membrane proteins could exist. Permeases, for instance, are integral membrane proteins that aid in the passive diffusion of specific substances (such as glucose) across the cell membrane.
