Give reason: -
1)vegetables release water after salt is added to them
2) nucleus is absent in red blood cells
3) the skin of your fingers shrinks when you wash clothes for a long time
4) inner membrane of mitochondria is folded
5) vegetable vendors regularly sprinkle water on the vegetables in their baskets.
6)endocytosis occurs only in animals

1 reason :
there are two reasons for this due to attraction of positive salt ions or negative water ions or it happens because the vegetable has more concentration of water init while in surrounding has low concentration of water so they try to lose water to attain equilibrium with respect to their surrounding...this is called osmosis...
2 reason:
due to absence of nucleus in red blood cells it is biconcave in shape
it is absent so that RBCs have more space to carry out oxygen 
also this absence make the cell able to bend whenever it is passed through bloodstream:)
3 reason:
our skin in water shrinks because the outermost layer of our skin swells by absorbing water but at the same time underneath layer gets tightly attach to it ,,,to compensate the surface area so it seems shrink...
4 reason:
to increase the surface area as a result of which large and faster production of ATPs takes place ...
5 reason:
so that vegetables do not get dry ,,, because they dry they do not look fresh...
6 reason:
endocytosis is a process in which cell membrane engulfs material... but in plant cell cell membrane is not present they have cell walls :)
