Definitions for "Mesophyll"
Mesophyll is the internal tissue of a plant leaf, excluding the vascular bundles. All mesophyll cells contain chloroplasts, for photosynthesis, which lie close to the edge of the cell to gain maximum light and gas supply. Mesophyll tissue also contains numerous intercellular spaces, which communicate with the atmosphere outside the leaf via stomata.
The photosynthetic layer of leaves between epidermal layers.
