Question

State what happens when: (a) Dry apricots are left for sometime in pure water and later transferred to sugar solution. (b) Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it? (c) Golgi appatatus is removed from the cell?

Answer 1

hello there !! :))
..............................................................................
.a.) When a dry apricot is placed inside pure water for some time, it will swell up as water enters inside the apricot. It occurs due to endosmosis. Here the concentration of solute is lower in water than inside the apricot. Thus water enters inside to maintain equilibrium.

After that if the swollen apricot is placed inside sugar solution it will shrink again due to exosmosis. As the sugar solution has higher solute concentration the liquid inside the apricot comes out towards the solution with higher concentration resulting in shrinkage of the fruit.

b.) Putting the leaf in boiling water kills all the cells, hence putting a sugar solution will have no effect as plasmolysis cannot happen in dead cells.

c.) In absence of golgi apparatus the cells will not be able to synthesize something new completely as packaging is done by Golgi apparatus. So no secretions would happen.
