Vedclass · Answer

(C) In plants,the short-distance transport of substances such as gases,water,minerals,hormones,and nutrients occurs through two primary mechanisms:$1$. Diffusion: This is a passive process where molecules move from a region of higher concentration to a region of lower concentration.$2$. Cytoplasmic streaming: This is the movement of the fluid substance (cytoplasm) within a plant cell,which is often supplemented by active transport to move substances across membranes against the concentration gradient.Therefore,both diffusion and cytoplasmic streaming (supplemented by active transport) are involved in short-distance transport.
