Long extension of the cell wall to absorb water and nutrients
|
Detailed explanation-1: -For example, compared to other plant cells, root hair cells have thin cell walls, which makes it easier for water molecules to enter the cell. The cells have a long extension to increase their surface area, thereby increasing the rate of absorption of water and minerals.
Detailed explanation-2: -Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration in order to provide the energy needed for active transport.
Detailed explanation-3: -The root hairs are suited for absorbing water from the soil because: The root hairs present a large surface area. The more the surface area, the greater is the absorption. Each root hair has a semi-permeable membrane.
