Answer 2

Answer:

Water is found in the spaces between the soil particles. Water and mineral salts first enter through the cell wall and cell membrane of the root hair cell by osmosis. Root hair cells are outgrowths at the tips of plants roots. They function solely to take up water and mineral salts. Root hair cells do not perform photosynthesis and do not contain chloroplasts as they are underground and not exposed to sunlight. These cells have large vacuoles which allow storage of water and mineral salts. Their small diameter (5-17 micrometers) and greater length (1500 micrometers) ensure they have a large surface area over which to absorb water and mineral salts. Water fills the vacuole of the root hair cell.

So, the correct option is 'It increases the surface area of absorption'....
