Solution
The correct option is A True
Plants require nitrates and other such minerals for growth. The concentration of nitrates is usually higher within the plant roots than it is in the soil surrounding it. The plant cannot depend on diffusion as the nitrates would diffuse outward of root cell and move into the soil. Hence, the cells need to use energy to actively transport nitrates across the cell membrane, against the concentration gradient, to ensure that it reaches other parts of the plant.
