Solution

Active transport.

Minerals cannot be absorbed by osmosis because this is the movement of water only. They cannot be absorbed by diffusion, because the minerals are in very low concentration. Instead, active transport is used.

With respect to the given assertion and reason, choose the correct option.
Assertion (A): Water and minerals are absorbed from roots and are transported upwards to various parts of the plant.
Reason (R): The process by which a substance absorbed from the roots of the plant is moved to the upper part of the plant is known as active transport.

Q. Assertion :Ions are absorbed from the soil by active transport only. Reason: The proteins present in the membranes of root hair cells passively pump ions from the soil into the cytoplasm of the epidermal cells.

Q. Assertion :Diffusion is a passive type of transport. Reason: Osmosis is an active process of membrane transport.
