|
|
|
It has a large vacuole to store food
|
|
|
It has a long and narrow extension to increase surface area to volume ratio for absorption
|
|
|
It has a lower water potential than surrounding soil for osmosis
|
|
|
It links directly to the xylem for water transport
|
Detailed explanation-1: -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-2: -Endosmosis: It is a type of osmosis, in which water enters the cell from the surrounding. Here, endosmosis is seen as water enters the root hairs from the soil. This feature helps in the absorption of water in plants through roots.
Detailed explanation-3: -So, the correct answer is ‘-1 to-4 atm’
Detailed explanation-4: -Root hairs collect water and mineral nutrients in the soil which is sent throughout the plant.
