The fluid mosaic model of plasma membrane proposes that membranes are:
Correct answer: B. Semisolid
- A. Solid
- B. Semisolid
- C. Fluid
- D. Liquid
Explanation
The model suggests that phospholipids are able to diffuse in their layers and the proteins of the membrane appear to give a mosaic appearance. The first part of this model therefore also suggests that the membrane is fluid in nature.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
