Microvilli are

Explanation:
Microvilli are projections that increase the cell's surface area. They are tiny, finger-like extensions of the plasma membrane with a core of actin filaments, which supports a large surface area to maximize absorption and secretion. This is why they're abundant in absorptive tissues like the small intestine and kidney tubules. They are non-motile, unlike structures such as cilia or flagella that move the cell, and they are not hollow tubes. They don’t form a microtubule-based ciliary apparatus or function as motor proteins for vesicle transport.
