Its function is fundamental because various processes take place such as breathing, chlorophyll assimilation (or photosynthesis), gas exchange (by the stomas), absorption of sunlight, and transpiration.

The leaf has openings located mainly in the epidermis on the underside of the leaf called stomas, flanked by reniform cells and the occlusive cells that are sawn and opened according to external environmental conditions.

Sometimes, the leaf’s base dilates into a sheath, and it comes to wrap the stem in a greater or lesser proportion. When the leaf is stalkless, it is called sessile or sitting.

The upper face or bundle is bright green and soft to the touch, while the lower front or back is paler and sometimes rough.

The green color of the leaf blade of almost all leaves is due to chlorophyll, a pigment that plants use to make the sugars called carbohydrates from water and carbon dioxide.

Not all leaves are green; many contain other pigments that mask the green of chlorophyll and some lack chlorophyll in all or parts of the leaf blade.

The coloring that the leaves acquire in autumn is almost always due to the decomposition of the chlorophyll, which exposes these other pigments.

The leaves have very varied forms, which are classified according to whether they have a single leaf per petiole, then called single leaves.

If they have several limbs, they are called compound leaves. These categories, in turn, are subdivided according to the shape of the leaf blade, the structure of the border, and the type of ribbing.

They are also classified by apex, base, margin, arrangement, shape, etc.
