Question

What is meant by ‘passive absorption’ of minerals by plants.

Answer 1

Explanation:

Passive absorption is a process where water is absorbed as a result of tension created by transpiration pull. It occurs mainly due to the activity of upper part of the plant such as shoot and leaves.

Answer 2

Passive absorption of minerals by plants.

Explanation:

• Passive absorption’ of minerals is the type of absorption of ion by plants that do not include any metabolic energy consumption.  
• This absorption is solely by the physical absorption technique like the diffusion technique.
• In diffusion the root absorbs the mineral elements by the downward flow of energy without consumption of metabolic energy.
• When the plant tissues are transferred from the low concentration medium to high concentration medium the rapid flow of ion takes place.
