When scientists assessed the ability of corn and tobacco to take up zinc from the environment, they found that different plant parts accumulated differing amounts of zinc. In both cases, which plant part accumulated the most zinc? Group of answer choices

A. cobs or pods

B. stem

C. seeds

D. leaves

Option D, leaves

Explanation:

The maximum concentration of zinc is accumulated both in the leaves and stem of corn and tobacco plants. But comparatively it is higher in the leaves than in the stem.

Zinc is a micro nutrient as it is required only in a small amount and it is found that plants will lesser zinc concentration dry out easily.

Also the relation between the zinc absorbed is linear to the accumulation of zinc in the leaves. Hence, the higher the zinc absorbed in the corn and tobacco plants, the higher is the zinc accumulating in the leaves.

Hence, option D is correct
