Study of internal structure of plants is called anatomy. 0000007008 00000 n 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. It consists of a flattened portion, called the blade, that is attached to the plant by a structure called the petiole. The outer surface of the leaf has a thin waxy covering called the cuticle (A), this layer's primary function is to prevent water loss within the leaf. v.1. Leaves may be simple, with a single leaf blade, or compound, with several leaflets. Longitudinal and transversal sections of mature leaf blades Leaves with a single undivided blade are called simple, those with two or more leaflets are called compound.

Thus in these plants C 4 pathway occurs. Rubber trees are easily recognizable for being woody, medium to large-sized plants, having a typical deciduous behavior, and especially because they produce latex. dimorphic chloroplast. leaf anatomy, for the coordination of water status and water flow across scales in plants, and for stomatal regulation, which may be influenced by microscale variations in leaf water potential (Buckley, 2005; Mott, 2007). Leaf morphology Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. 0000024706 00000 n [7�u�۽�_k��f&_ln�zS��v����$�3[[%���y9S�P���|� Q�E�D��L�K\z\p{\��|�'?��ܞ&" Leaves are collectively referred to as foliage, as in "autumn foliage". Two epidermal layers are present, one each on upper and lower surfaces. Mesophyll can then be divided into two layers, the palisade layer (D) and the spongy layer (F).
