In plants,the epidermis layer functions like a covering of skin to protect the leaf,while vascular bundles carry water and nutrients through the leaf.The palisade mesophyll layer is responsible for most of the photosynthesis that occurs,while the spongy mesophyll layer underneath it aids in the exchange of gases (CO₂ and O₂)and water vapor.In which leaf tissues would one expect to find the highest density of chloroplasts?

Question

Quizplus · Accepted Answer

The Palisade mesophyll layer is responsible for most of the photosynthesis that occurs in a leaf, which means that it contains the highest density of chloroplasts. Chloroplasts are the organelles that carry out photosynthesis, so it makes sense that the layer responsible for photosynthesis would contain the highest density of chloroplasts.
