What are the main structural differences between a potato and elodea?

A. Elodea has tuber structures, while potatoes have leaves.
B. Potatoes have chloroplasts, unlike elodea.
C. Elodea is a root vegetable, while potatoes are aquatic plants.
D. Elodea has cells with chloroplasts, but potatoes do not.

Answer :

Final answer:

The key structural difference between a potato and Elodea is that Elodea cells contain chloroplasts for photosynthesis, whereas a potato, as a tuber, contains amyloplasts for starch storage but does not have chloroplasts. So the correct option is d. Elodea has cells with chloroplasts, but potatoes do not

Explanation:

The main structural differences between a potato and Elodea are related to their respective plant structures and cellular components. A potato, part of an herbaceous plant, is a tuber, which is a type of below-ground modified stem adapted for starch storage. It has parenchyma cells containing amyloplasts (starch-storing plastids) but does not have chloroplasts, as it is not involved in photosynthesis. In contrast, Elodea is an aquatic plant with cells that contain numerous chloroplasts for photosynthesis.

The chloroplasts give Elodea its green color and are involved in harvesting light to make food for the plant, whereas potato tubers are involved in storing nutrients and have 'eyes' which are embryonic branches that can sprout into new plants.
