Microvilli:
In some cells the membrane is thrown into minute fingerlike projections or folds called microvilli which greatly increase the surface area of the cell available for absorption or passage of materials and for the binding of signaling molecules.
Microvilli are slender extensions of the plasma membrane that increase its surface area. They are found in cells involved in absorption, such as in the small intestine, where they help in increasing the efficiency of nutrient absorption.

What slender extensions increases the plasma membrane's surface?
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.
What part of the cell is a slender extension of plasma membrane that increase its surface area?
microvilli
What do you call the infoldings of the inner membrane of the mitochondria?
The infoldings of the inner membrane of the mitochondria are called cristae. These structures increase the surface area of the inner membrane, allowing for more space for chemical reactions involved in cellular respiration to take place.
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.
Extensions of root epidermis used to increase absorption are called?
Root hairs. They are thin, hair-like extensions of root epidermal cells that greatly increase the surface area available for absorption of water and nutrients from the soil.
What are slender extensions of the plasma membrane that increase its surface area?
Microvilli

What part of the cell is a slender extension of plasma membrane that increase its surface area?
microvilli
What plasma membrane extensions create the most surface area for the cell?
Microvilli are plasma membrane extensions that create the most surface area for the cell. These finger-like projections are found in cells involved in absorption, such as the cells lining the small intestine, and increase the cell's ability to transport nutrients.
Does the cristae increase or decrease the surface area of the inner membrane?
Cristae increases the surface area of the interior membrane of the mitocondria.
What is the purpose of the folded layers of membrane?
To increase the surface area.
What are The short extensions of the cell wall called?
The short extensions of the cell wall are called microvilli. They are found on the surface of some cells and serve to increase surface area for absorption and secretion of substances.

What is an internal support structure of an animal that gives the body structure and shape?
cytoskeleton is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to, as well as forming organelles that extend from the cell. Indeed, cytoskeletal elements interact extensively and intimately with the cell membrane.[4] Anchoring proteins restricts them to a particular cell surface - for example, the apical surface of epithelial cellsthat line the vertebrate gut - and limits how far they may diffuse within the bilayer. The cytoskeleton is able to form appendage-like organelles, such as cilia, which are microtubule-based extensions covered by the cell membrane, and filopodia, which are actin-based extensions. These extensions are ensheathed in membrane and project from the surface of the cell in order to sense the external environment and/or make contact with the substrate or other cells. The apical surfaces of epithelial cells are dense with actin-based finger-like projections known as microvilli, which increase cell surface area and thereby increase the absorption rate of nutrients. Localized decoupling of the cytoskeleton and cell membrane results in formation of a bleb.Source(s):VV....I...I

What is surface area and how you can decrease or increase surface area?
Surface area refers to the total area that covers the surface of an object or structure. To decrease surface area, you can reduce the dimensions of the object or change its shape to be more compact. To increase surface area, you can add extensions, rough textures, or indentations to the object's surface.
