Article shared by : The leaf both morphologically and anatomically is the most variable plant organ. They have been grouped as โfoliage leaves, cataphylls, hypsophylls and cotyledons. Of these the foliage leaves are the principal photosynthetic organs.

(i) Auriculate or Semiamplexicaul: In this type of leaf base, the sheathing leaf base only partially encloses the stem (Fig. 4.2 E). (ii) Amplexicaul: This type of leaf base completely encloses the stem, e.g., Sonchus (Fig. 4.2-1) Polygonum etc. 3. Decurrent Leaf Base: ADVERTISEMENTS:

The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Both layers of the mesophyll contain many chloroplasts. Figure 30.10. 1: Mesophyll: (a) (top) The central.

The midrib contains the main vein (primary vein) of the leaf as well as supportive ground tissue (collenchyma or sclerenchyma). Figure 3.4.1. 1: A typical eudicot leaf. Many leaves consist of a stalk-like petiole and a wide, flat blade (lamina). The midrib extends from the petiole to the leaf tip and contains the main vein.

A Guide to Understand Leaf with Diagram Photosynthesis is the process that generates food for the plant, and leaves play a significant role in the process. They convert photon energy into chemical energy. The structure of the leaf contributes to the process. It also participates in the transportation of water and nutrients.

Thus, the leaf of a firmoss ( Huperzia, a type of lycophyte and not a true moss) has a different evolutionary origin than the leaf of a tree fern, which has a different evolutionary origin than the leaf of a cycad (a gymnosperm). Leaves that have separate evolutionary origins.

Like the stem, the leaf contains vascular bundles composed of xylem and phloem (Figure 3.4.2.6 โ 7 3.4.2. 6 โ 7 ). When a typical stem vascular bundle (which has xylem internal to the phloem) enters the leaf, xylem usually faces upwards, whereas phloem faces downwards. The conducting cells of the xylem (tracheids and vessel elements.

The anatomy of a leaf has everything to do with achieving the balance between photosynthesis and transpiration in the environment in which the plant grows. Plants that grow in moist areas can grow large, flat leaves to absorb sunlight like solar panels because sunlight is likely more limiting than water. Plants in dry areas must prevent water.

Figure 30.8.1 30.8. 1: Parts of a leaf: A leaf may seem simple in appearance, but it is a highly-efficient structure. Petioles, stipules, veins, and a midrib are all essential structures of a leaf. Within each leaf, the vascular tissue forms veins. The arrangement of veins in a leaf is called the venation pattern.

How do they work? An microphotograph of a stoma shows the two guard cells which regulate its opening and closure to limit water loss, excrete oxygen, and absorb carbon dioxide. The openings or pores in stomata are formed by two specialized sclerenchymal cells, the guard cells ( Figure above ).
