The internal tissues of the leaf are covered on the upper surface by the upper epidermis. Stomata are also usually absent or few except in special cases. Plant Organs - Leaf. Leaf mass per unit area (LMA) and internal leaf anatomy often affect net gas exchange because of their effects on internal CO 2 conductance to the site of carboxylation, internal shading, competition for CO 2 among carboxylation sites, nitrogen concentration and its partitioning. 0000003640 00000 n Anatomy of leaf is the detailed study of internal structure of a leaf, usually revealed by its dissection. The word mesophyll is greek and means "middle" (meso) "leaf" (phyllon). Plants have cells as the basic unit, cells are organised into tissues and in turn the tissues are organised into organs.

The leaves and stem together form the shoot. Leaves are classified into mainly two types based on their structure, dorsiventral, and isobilateral. The blade has many layers that not only help the plant move but also help it store materials and byproducts of photosynthesis. A leaf (plural leaves) is the principal lateral appendage of the vascular plant stem, usually borne above ground and specialized for photosynthesis. ]M��i 2.
