Diffusion doesn’t require energy. Why do plants expend energy in active transport to transport minerals into root hairs? a) Minerals are strongly attracted to soil particles. b) Mineral concentrations in the soil are too high for diffusion. c) Minerals are too large for diffusion. d) Mineral concentrations in the soil are too low for diffusion.

a) Minerals are strongly attracted to soil particles.
b) Mineral concentrations in the soil are too high for diffusion.
c) Minerals are too large for diffusion.
d) Mineral concentrations in the soil are too low for diffusion.
Answer
Mineral concentrations in the soil are too low for diffusion.
Explanation: Active transport is used because minerals in the soil are at lower concentrations compared to the plant’s internal environment, making diffusion insufficient for uptake.
