In plan roots, the casparian strip____?

QUESTION 22 In plant roots, the Casparian strip O provides energy for the active transport of minerals into the stele from the cortex OB. ensures that all water and dissolved substances must pass through a cell membrane before entering the vascular calendar Ocensures that all minerals are absorbed from the soil in equal amounts D.aids in the uptake of nutrients from the soil

Answer 1

Answer 22) B ensure what all water and dissolved substances must pass through a cell membrane before entering the vascular calender.

Casparain strips are present inside the inner layer (endodermis) of the plant root, it is usually one cell layered throughout and it prevents excessive amount of soil solution to be uptaken from the soil at once and hence ensures that it must pass through a cell membrane before it enters into the vasculature of the plant.
