Question

Mark out the incorrect statements.
i) Bulk flow can be achieved through a positive hydrostatic pressure.
ii) Bulk flow can achieved through a negative hydrostatic pressure.
iii) Plasmolysis usually occurs in nature
iv) Imbibition also involves diffusion of water.

• A. i & iii
• B. Only iii
• C. iii & iv
• D. ii & iv

Answer 1

The correct option is B Only iii

Plasmolysis doesn't occur in nature. It is the separation of plant cell cytoplasm from the cell wall due to the loss of water. It is mostly a laboratory-induced process and doesn't occur naturally.

Imbibition is one of the types of diffusion of water in which water is absorbed by colloidal solids.

Bulk flow is achieved through both positive and negative hydrostatic pressure.

So the correct option is C.
