Answer 2

Correct answer: Active water absorption

Active absorption is the process of absorption of water that occurs through the activity of plant root hairs. It occurs by the osmosis or by the use of active transport in order to move the solute molecules in order to change the water concentration gradient, which forces the water into the cells of the root hairs.

Root hairs are hair-like thin structures that are found in the roots of the plants, they are helpful for plants as they are known to increase the surface area by which plants can take water.
