Why are epithelial cells taller then they are wide?
Epithelial cells are taller than they are wide to maximize their surface area for absorption and secretion. This shape allows for more efficient exchange of molecules and nutrients across the cell surface. Additionally, the elongated shape of epithelial cells is important for maintaining tight junctions between adjacent cells, which helps create a barrier to protect underlying tissues.
What tissue is microvilli and goblet cells associated with?
Microvilli are associated with the epithelial tissue lining the small intestine, where they increase surface area for absorption. Goblet cells are specialized cells found in the epithelial tissue of the respiratory and digestive tracts, where they secrete mucus to protect and lubricate the lining of these organs.
What are disk like cells?
Disk-like cells refer to cells that have a flattened, disk-like shape, often found in tissues like epithelial cells. Their shape allows for efficient diffusion of substances across their surface and helps in the absorption and secretion of molecules. These cells are commonly found in tissues that require a large surface area for exchange of materials.
Which has the greater surface area one large cell or 27 smaller cells?
27 smaller cells would have a greater surface area than one large cell. This is because the total surface area of the smaller cells would be greater due to the additional surface area of the cell membranes around each individual cell.
The surface area for diffusion across the membranes of cells in simple columnar epithelium is increased by the presence of?
Microvilli, which are tiny finger-like projections on the surface of the cell membrane. These structures increase the surface area available for diffusion and absorption of molecules in simple columnar epithelial cells.
What is microvilli'?
Tiny projections on the free surface of some epithelial cells; increase surface area for absorption
How do small intestinal epithelial and root hair cells function in nutrient procurement?
Small intestinal epithelial cells have microvilli that increase surface area for nutrient absorption, and transporters that facilitate nutrient uptake. Root hair cells in plants have a large surface area and specialized transport proteins to absorb water and nutrients from soil. Both cells play a crucial role in nutrient procurement by maximizing surface area for absorption and utilizing specialized transport mechanisms for efficient nutrient uptake.

What increases the surface area of certain epithelial tissues?
microvilli, tremendously increase exposed surface area in epithelial tissue.
What is microvillus?
it is a thin protuberance present in great abundance at the surface of some epithelial cells, notably in the gut, thus increasing the surface area available for absorption
Why do cells need a large surface area?

What forms a brush border extension of epithelial cells?
Microvilli form the brush border extension of epithelial cells in the small intestine and kidney. These microscopic finger-like projections increase the surface area of the cells, aiding in the absorption of nutrients and water.

A high density of microvilli is to be expected especially on the surface of epithelial cells located in the?
Small intestine, where microvilli increase the surface area for absorption of nutrients.
Which has the greater surface area one large cell or 27 smaller cells?
27 smaller cells would have a greater surface area than one large cell. This is because the total surface area of the smaller cells would be greater due to the additional surface area of the cell membranes around each individual cell.
How is ileum of a mammal adapted for the absorption of digested food?
1/ the lining has A a very large surface area. 2/ the length of the intestine (ileum 3.5m) help increase the surface surface area for absorption. 3/ millions of villi provide a large surface area in contact with the digested food. 4/ hundreds of micro villi on the surface cells (on each villus) increase the surface area for absorption. your welcome :)
