What are the two main types of plant tissues involved in photosynthesis?

The two main types of plant tissues involved in photosynthesis are palisade mesophyll and spongy mesophyll. Palisade mesophyll cells are rich in chloroplasts and are responsible for capturing light energy and conducting photosynthesis. Spongy mesophyll cells also contain chloroplasts and are involved in gas exchange and support for the process of photosynthesis.
