It is either nucleus, haemoglobin, thick outer cell wall or microvilli.
Microvilli are also called Cilia
Microvilli cells are simple columnar epithelium. Stratified epithelia don't have cilia or microvilli because they are on the inner layers of epithelia. Think about it, cillia and microvilli are used to help the processes of absorption and secretion within the lumen. ex: upper respiratory tract.
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.
microvilli
It is either nucleus, haemoglobin, thick outer cell wall or microvilli.
Microvilli is plural and Microvillus is singular.
Nucleus is not a basic component of a cell membrane. The cell membrane consists of a phospholipid bilayer with embedded proteins, while the nucleus is a distinct organelle that contains the cell's genetic material.
microvilli are ONLY found in animals
Microvilli are also called Cilia
Microvilli are slender extensions of the plasma membrane that increase its surface area for absorption and secretion. They are commonly found in cells that are involved in absorption, such as epithelial cells in the intestine and kidney.
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.
Microvilli
the microvilli
The core of microvilli is attached to the plasma membrane. It also contain a bundle of about 40 filaments of actin.
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.
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.
