microvilli
|
Explanation:
Detailed explanation-1: -Microvilli are extensions of villi and are made of microfilaments, specifically actin filaments, as well as cytoplasm. These actin filaments are crucial to the structure of microvilli as they support their structure and increase the surface area of the epithelial cells in the locations they are in.
Detailed explanation-2: -Microvilli, found in tightly packed arrays on the apical surfaces of polarized epithelial cells, increase the surface area of the cell exposed to the lumen to enhance absorption and secretion.
Detailed explanation-3: -Answer: ‘Absorption’ is the characteristic feature of the epithelial cells of the intestine.
