Inside microvilli you have actin, and inside cilia you have microtubules. Cilia are larger than microvilli, and cilia can be seen in the upper GI tract to beat away mucous which traps bacteria, virus, and other particles, microvilli is often seen in the intestines of the GI tract for nutrient absorption.

What is the plural of microvilli?

Microvilli is plural and Microvillus is singular.


What type of cell functions does the presence of microvilli typically indicate?

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.


What are the folds of the plasma membrane that increase the cells surface area?

The folds of the plasma membrane that increase the cell's surface area are called microvilli. They are small, finger-like projections found on the surface of certain types of cells, particularly in cells involved in absorption, to increase the surface area for better nutrient absorption.


Increase the membrane surface area?

One way to increase membrane surface area is to introduce folds or projections in the membrane structure. These folds, known as microvilli or villi, can significantly increase the surface area available for processes such as diffusion and absorption to occur. Another method is to use specialized structures like cilia or flagella that further increase the surface area while also providing motility.


Are there microvilli in bacterial cells?

Yes of course. Due to the Golgi Apparatus interacting with the chloroplasts in the palisade cells coupled with the protein synthesis in the lac operon, the microvilli will be present to digest the proteins synthesised by osmosis. This results in the excretion of toxins by the bacteria and in certain species causing sympatric speciation.
