The spongy mesophyll consists of air spaces that aid in the diffusion of gases. palisade mesophyll spongy mesophyll lower epidermis lower cuticle. These cells have a lot of chloroplasts in them, which is why they're the main sites of photosynthesis in the leaf (since chloroplasts conduct photosynthesis). Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, converting the energy in light to the chemical energy of carbohydrates. At the level of the veins, the clusters of palisade cells were fewer, usually providing an inadequate sample. Together, the palisade layer and the spongy layer make up the mesophyll.

Furthermore, palisade … Stomata are tiny pores that permit gases and other materials to enter into and move out of the leaf. In this regard, what is the function of Palisade Mesophyll? Palisade and spongy mesophyll cells are sub-tissues that have different morphologies and physiologies. Cell-type-specific transcription factors are key to deducing the distinct functions of specialized cells from gene expression profiles. Below the midrib bundle is a zone of collenchyma. Together, the palisade layer and the spongy layer make up the mesophyll. The palisade layer is found below the upper epidermis. 2.
