How do the structures or lack of structures of an onion cell and Elodea cell compare to where they are each found?

Onion cells are typically found in the storage tissues of the onion bulb, which results in a lack of chloroplasts and a more compact structure suited for nutrient storage. In contrast, Elodea cells, found in aquatic environments, possess chloroplasts for photosynthesis, giving them a more elongated and flexible structure to maximize light absorption. The presence of a rigid cell wall in both cell types provides structural support, but the differences reflect their adapted functions in their respective environments.
