Vedclass · Answer

(B) $\Rightarrow$ Plants require various transport mechanisms for the movement of ions,minerals,and organic substances because:$(i)$ Diffusion is a slow process and is only effective for short-distance transport.$(ii)$ Plants need to transport materials over long distances,such as from roots to leaves (upward) and from leaves to other parts (downward/lateral).$(iii)$ Diffusion cannot account for the bulk movement of substances required to meet the metabolic demands of a growing plant.$(iv)$ Therefore,specialized mechanisms like active transport and mass flow (translocation) are necessary to ensure the efficient distribution of nutrients and water throughout the plant body.

Various types of transport mechanisms are needed to fulfill the mineral requirements of a plant. Why are they not fulfilled by diffusion alone?
