Active Process Of Absorption

During process of active absorption of water

[A]: The movement of ions from endodermis to xylem elements is an active process. [R]: It requires the involvement of metabolic energy that comes from respiration.

Assertion :- Most of the mineral absorption by plant is active process. Reason:- Some ions also move in epidermal cells passively.

Statement: Threshold energy of a reaction is independent of temperature. Explanation: The energy of activation however decreases with increase in temperature.

Statement: A catalyst always lower the energy of ectivation. Explanation: The catalyst-reactant interaction forms activated adsorbed complex and adsorption is always exothermic.

Statements : The activity of catalyst is more or less specific. Explanations : A catalyst for one reaction is not necessary to catlyse the other reaction .
