Microvilli (singular: microvillus) are microscopic cellular membrane protrusions that increase the surface area of cells. They are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction.
microvilli
Microvilli are formed by elongation of actin filaments in the cytoskeleton of the cell. The actin filaments push against the plasma membrane, creating finger-like projections called microvilli. These structures increase the surface area of the cell, aiding in absorption and secretion processes.
Yes, a cell membrane can have bumps on it known as microvilli. Microvilli are small, finger-like projections that increase the surface area of the cell membrane, allowing for more efficient absorption of nutrients or secretion of substances.
No, microvilli do not have a nucleus. Microvilli are tiny, finger-like projections found on the surface of certain cells, primarily in the intestines and kidneys, and they increase the surface area for absorption. They are extensions of the cell membrane and do not contain their own genetic material or organelles like a nucleus. Instead, they are supported by the underlying cytoskeleton of the cell.
There are three main types of cell extensions in biology: cilia, flagella, and microvilli. Cilia are short, numerous hair-like projections that help with movement and sensing. Flagella are long, whip-like extensions that aid in cell movement. Microvilli are small, finger-like projections that increase the surface area of cells for absorption and secretion.
the microvilli
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.

microvilli
The presence of microvilli typically indicates that the cell is involved in absorption, as microvilli increase the surface area of the cell membrane, allowing for more efficient nutrient absorption. Cells with microvilli are commonly found in tissues involved in absorption, such as the small intestine.

Since the function of the microvilli is to increase the cell's surface area, it can only exist in the animal cell and not plant cell because the plant cell has a cell wall and is therefore rigid and unable to expand in size.

Brush border cells are composed of microvilli, which are small finger-like projections on the surface of the cell. These microvilli greatly increase the surface area of the cell, allowing for more efficient absorption of nutrients and other molecules. Brush border cells are commonly found in the small intestine and kidney.
