The soft tissue (green parenchyma) inside a leaf, between the lower epidermis and the upper, chiefly concerned in photosynthesis.
The tissues of a leaf that are located in between the layers of epidermis and carry on photosynthesis, consisting of the palisade layer and the spongy parenchyma . Most mesophyll cells contain chloroplasts.
The definition of mesophyll is the soft tissue inside a leaf.
An example of mesophyll is the tissue in the leaf that plays an important role in photosynthesis.
The photosynthetic tissue of a leaf, located between the upper and lower epidermis.
The only pathways for the gases which thus pass between the cells of the mesophyll and the outside air are the stomata.
In fleshy leaves which contain a great bulk of tissue in relation to their chlorophyll content, the central mesophyll contains little or no chlorophyll and acts as waterstorage tissue.
In the leafy shoot this function is mainly localized in the cortical tissue of the leaves, known as mesophyll, Mesophyli.
The cells of these sheaths are often distinguished from the rest of the mesophyll by containing little or no chlorophyll.
These bodies, known technically as chioroplaIts, are found embedded in the protoplasm of the cells of the mesophyll of foliage leaves, of certain of the cells of some of the leaves of the flower, and of the cortex of the young twigs and petioles.
