Answer: Â Microvilli
Explanation:
The main role of microvilli is to increase the area of a membrane through which the cell can absorb nutrients. Nutrients from digested food are absorbed into the cells of the intestines.
Membrane Exocytosis
It increases PM Area during Cell Spreading. It is found that the total cell surface area increased by about 20% through exocytosis during cytokinesis. The furrowing observed during cytokinesis was indispensable for the cell membrane increase, and vice versa.
