The palisaded cells are tightly packed, and they help in photosynthesis. On the other side, the spongy parenchyma contains air spaces. These air spaces allow gaseous exchange between the leaf and the outside environment. Both these layers contain many chloroplasts.

Web24 nov. 2024 · Mesophyll cells are the photosynthetic cells in the leaves of plants. They are responsible for absorbing carbon dioxide (CO2) from the air and converting it into organic matter, such as glucose. CO2 enters the leaves through tiny pores called stomata. Once inside the mesophyll cells, CO2 is used in the Calvin Cycle to produce glucose.

WebMelvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway.
