- Mesophyll
- Stoma
- Stalk
- Vein
Explanation
The tissue found between the upper and lower epidermis of a leaf is known as the mesophyll.
In most plants, the mesophyll is composed of two distinct layers:
Palisade mesophyll:
Located just below the upper epidermis, this layer consists of tightly packed, column-shaped cells that are rich in chloroplasts.
It is the primary site of photosynthesis.
Spongy mesophyll:
Located below the palisade layer, this tissue has irregularly shaped cells with large air spaces between them.
These spaces allow for the circulation of carbon dioxide, oxygen, and water vapor.
