Microvilli is very common in these cells. They increase the absorption area.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. <u>Their principal function is to absorb</u>. The microvilli of the intestinal epithelium are very uniform in size and distribution.
D. CO₂ is needed to produce sugars in the Calvin cycle.
Explanation:
We know that CO₂ is the prime element for photosynthesis.
CO₂ is the only source that supplies carbons in this process. With the help of CO₂, water, light, minerals, and chlorophyll, six-carbon glucose is formed.
This glucose is converted to starch and is stored in fruits or in the parts of plants for further use.
