How presence of root hair cells on roots enables the efficient absorption of water and minerals?
They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.

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.
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 :)
Aids in absorption of vitamin b12?
Intrinsic factor, a protein produced in the stomach, helps in the absorption of vitamin B12. This vitamin is crucial for red blood cell formation and neurological function. Absorption of vitamin B12 occurs in the small intestine, where it binds to intrinsic factor for transport into the bloodstream.
The most striking aspect of intestinal histology is the?
villi, which are finger-like projections that increase surface area for absorption; crypts of Lieberkühn, which are invaginations where new epithelial cells are produced; and the presence of various cell types, including enterocytes, goblet cells, Paneth cells, and enteroendocrine cells.
How does folding the small intestine help to speed up absorption?
Folding the small intestine into numerous finger-like projections called villi increases the surface area available for absorption. This allows for more contact between nutrients and the absorptive cells, speeding up the process of absorption into the bloodstream. Additionally, the presence of microvilli on the surface of the absorptive cells further enhances absorption efficiency.
Describe three ways a plants leaf is adapted for photosynthesis?
The broad, flat shape of a plant's leaf maximizes the surface area available for absorbing sunlight. The presence of chloroplasts containing chlorophyll within the leaf cells allows for the absorption of light energy needed for photosynthesis. The presence of stomata on the leaf surface enables gas exchange, allowing carbon dioxide to enter for photosynthesis and oxygen to exit as a waste product.
Function of flagella?
Enables cells to movement.
What is in the blood cells that enables them to carry oxygen?
Hemoglobin is the protein in red blood cells that enables them to carry oxygen. Iron is an important component of hemoglobin.
The end products of digestion enter the cells of a vertebrate by the process of what?
The end products of digestion enter the cells of a vertebrate through a process called absorption. This occurs mainly in the small intestine, where nutrients like glucose, amino acids, and fatty acids are absorbed through the intestinal lining into the bloodstream to be transported to cells throughout the body.
Function of columnar cells?
Absorption , protection .
