Question

explain cell membrane fluidity and asymmetry

Answer 1

Asymmetry:
In biology, the body plan of many organisms exhibit symmetry. Although the parts in a dividing plane or around an axis are not exactly the same, there is a significant correspondence in form, size, distribution, or arrangement of parts. Symmetry is observed particularly with regard to the external appearance of organisms. Bilateral organisms exhibit similarities between left and right sides. Radially symmetrical organisms have body plan in which every side is the same around an axis. In contrast, there are organismslacking external symmetry. Flounders (adult form where both eyes are on one side) and hermit crabs (having a large claw on one side) are examples of organisms exhibiting asymmetry.

Membrane fluidity:
In biology, membrane fluidity refers to the viscosity of the lipid bilayer of a cell membrane or a synthetic lipid membrane. Lipid packing can influence the fluidity of the membrane. Viscosity of the membrane can affect the rotation and diffusion of proteins and other bio-molecules within the membrane, there-by affecting the functions of these molecules.

Answer 2

a biological membrane or biomembrane is an enclosing or separating membrane that acts as a selectively permeable barrier within living things. biological membranes ,in the form of eukaryotic cell membranes,consists of a phospholipid bilayer with embedded ,integral and peripheral proteins used in communication and transportation of chemical and ions .
