Question

A researcher discovers a mutant pea plant that is missing the Casparian strip. What process will be affected in this mutant? both the diffusion of CO2 into the leaves of the plant and the opening and closing of stomata the ability of the plant to perform CAM the the diffusion of CO2 into the leaves selectivity of mineral nutrients absorbed by roots the opening and closing of stomata

Answer 1

Answer: Selectivity of mineral nutrients absorbed by roots

Step-by-step explanation:

The Casparian strip in the plants are waxy coating found in the roots of the plant which helps in absorbing excess of water into the plants.

These strips thickens the walls, thus preventing the excess of soil solution from being pulled by the roots into the central part of the plant.

It helps in selecting the type and amount of nutrient into the plant but the plant having no Casparian strip will reduce the selectivity of the nutrients.
