Active transport is usually associated with accumulating high concentrations of molecules that the cell needs, such as ions, glucose and amino acids. Examples of active transport include the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plants.
<span>The rate of diffusion of a substance depends on four factors which are: temperature, concentration gradients, diffusion distance and the diffusion and host material. The rate of diffusion is affected by differences in concentration gradient; the higher the difference in concentration gradient, the higher the diffusion rate. Thus, small concentration gradient will not increase the rate of diffusion. The correct option is A.</span><span />
