Answer:
hey all answer given with explaination..thanks..
Explanation:
a)When RBC is kept in concentrated solution, RBC will shrink. As the concentration of solute in the solution outside the cell is higher, water moves outside the cytoplasm and the cell membrane shrinks. This process of shrinkage of plasma membrane in presence of concentrated solution is known as plasmolysis.
b)When rheo leaves are boiled, this will shrink due to high temperature. The solute content within the leaves will falls out during heating due to osmosis.
c)Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell.
d)If the plasma membrane ruptures or breakdown then the cell will not be able to exchange material from its surrounding by diffusion or osmosis. Thereafter the protoplasmic material will be disappeared and the cell will die.
e)Dry apricots when placed in pure water swell due end osmosis (inward movement of water) and later when are transferred sugar solution exosmosis (outward movement of water) occurs and they shrink again.
