The process of exocytosis is also important in?

Question

a. the increase in the size of the cells
b.maintainig the osmotic balance between the cytoplasm and the cell exterior
c.the production of cell walls by plant cells
d. a and b
e.a , b, and c

Answer 1

Answer: b

Exocytosis is the process whereby a cell releases substances into its surrounding environment.

It usually is associated with a DECREASE in the size of cells and this eliminates options a, d and e.

Functions include: waste elimination (?b), cellular signalling, antigen presentation or other forms of surface protein production and renewal or recycling of plasma membrane and bound proteins (eg receptors).

Plant cell walls are formed at the time of cytokinesis - when the plant cell splits into two cells, the basis of the cell wall is formed between them.

Answer 2

The only plausible answer yo the question, is "B" maintaining the osmotic balance between cytoplasm and the exterior...
Why? because exocytosis is a dynamic phenomenon that will spend energy of ATP-ADP and carries outside of the cell, all kind of waste products of the same, that can or cannot be end products such as CO2, Water, Sodium etc....so, by expelling the ecess of one substance, the amount of inner osmles, (concentration) tends to remain constant.
The other ansers are plainly wrong-
