In brief state what happens when

(a) dry apricots are left for some time in pure water and later transferred to sugar solution?

(b) a Red Blood Cell is kept in a concentrated saline solution?

(c) the plasma membrane of a cell breaks down?

(d) the leaves are boiled in water first and then a drop of sugar syrup is put on it?

(e) Golgi apparatus is removed from the cell?

Answers (1)

a) A dry apricot placed in water for some time swells due to endosmosis and later transferred to sugar solution shrinks due to exosmosis (sugar solution acts as hypertonic to swelled apricot in water).

b) A red blood cell kept in concentrated saline solution loses water and shrinks because of exosmosis as the saline solution is hypertonic to Red blood cells' cellular fluid. This leads to the outward movement of water from the cell.

 c) When the plasma membrane of a cell breaks down, all the cellular contents such as cytoplasm, cell organelles etc. The plasma membrane acts as a boundary and packing structure which keeps its contents intact and differentiated from its surroundings.

d) When the leaf is boiled first and then a drop of sugar syrup is put on it, osmosis does not take place due to the death of the plasma membrane.

e) Golgi complex: The key function is modifying, packing and transferring the protein syntheses by ribosomes. Thus when Gthe olgi complex is removed, the cell function is hampered.
