Question

Are microvilli found in plant cells?

Answer 1

Hint: Microvilli on the surface of epithelial cells, such as those that line the intestine, increase the cell's surface area, making it easier for food and water molecules to be absorbed. These are small finger-like projections, about 1 micrometer in length, and 90nm or so in diameter. The microvilli are shorter and narrower than cilia.

Complete solution:-
Microvilli (singular: microvillus) are microscopic cellular membrane protrusions that enhance surface area for diffusion while minimising volume increase and are engaged in a range of processes such as absorption, secretion, cellular adhesion, and mechanotransduction.

Plasma membrane, which encloses cytoplasm and microfilaments, covers microvilli. Despite the fact that microvilli are cellular extensions, they contain few or no cellular organelles. A thick bundle of cross-linked actin filaments surrounds each microvillus. It serves as the foundation of the structure. The microvilli's core is made up of 20 to 30 densely packed actin filaments that are cross-linked by the bundling proteins fimbrin (or plastin-1), villin, and espin.

Microvilli do not exist in plant cells. Microvilli are microscopic cellular membrane projections found on the small intestine's inner side. Microvilli can be found on the plasma surface of eggs as well as the apical surface of epithelial cells. The plant cell lacks microvilli.

Note:-
The centrosome is a cell's microtubule-organizing core that is located near the nucleus of animal cells. Microvilli are formed as cell extension from the plasma membrane surface.
