Question

What is the process by which roots uptake nutrients?

Answer 1

Minerals :

1. The minerals are inorganic elements that a plant requires for its growth and development.
2. The uptake of minerals from the roots of plants can be active or passive transport.

Passive absorption :

1. The process of absorption of ions from soil into the epidermal cells of roots without using energy.
2. Some minerals are present in the soil as charged particles so cannot be transported by passive transport

Active absorption :

1. The process of absorption of ions from soil into the epidermal cells of roots occurs by utilizing energy ATP.
2. Inorganic minerals such as NO₃- , Mg+, Fe³⁺
