Answer :
The correct answer is (b) the microvilli trap the nutrients so the villi cells can absorb them. The microvilli increase the surface are a thereby it facilitates the absorption of the nutrients.
- In the simplest terms, microvilli are minuscule microscopic projections that are found in, on, and around cells.
- They may exist independently or with villi (projections of some mucous membranes, most specifically of the small intestine, which are tiny folds that project out like numerous fingers).
- Microvilli are even more minute folds that protrude like fingers from each villi.
- The surface of egg cells, the small intestine, and white blood cells are where microvilli are most frequently seen.
- On the apical surface of some epithelial cells, such those in the small intestine, thousands of microvilli come together to form a structure known as the brush boundary.
- Microvilli are a kind of surface protuberances that are rather polymorphic and are regularly packed in some tissues while being loosely positioned in others.
