NEET BIOLOGY

Detailed explanation-1: -They cannot be absorbed by diffusion, because the minerals are in very low concentration. Instead, active transport is used. The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient .

Detailed explanation-2: -Root hair cells They absorb mineral ions by active transport, against the concentration gradient.

Detailed explanation-3: -Active transport in the root hairs of plants allows plants to absorb mineral ions, which are necessary for healthy growth, even though the concentration of minerals is usually lower in the soil than in the root hair.

Detailed explanation-4: -Mineral ions must be transported against a concentration gradient. Active transport ensures that the required mineral ions are absorbed from the dilute solutions within the soil into the root hair cells. This process requires energy.

Detailed explanation-5: -Active transport is the process that helps to move the molecules against a concentration gradient. So, the active transport is the process that moves mineral ions into root hair cells through membrane proteins.
