Leaf Structure & Evolution Digital Atlas of Ancient Life
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.

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.

Definition of a Leaf 2. Parts of a Leaf 3. Types. Definition of a Leaf: The leaf is a flattened, lateral outgrowth of the stem in the branch, developing from a node and having a bud in its axil. It is normally green in colour and manuยญfactures food for the whole plant.

Figure 9.3. 2: Cross section of a hydrophytic leaf. Observe a prepared slide of a hydrophyte, such as Nymphaea, commonly called a water lily. Note the thin epidermal layer and the absence of stomata in the lower epidermis. In the spongy mesophyll, there are large pockets where air can be trapped.

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.

What is photosynthesis? Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

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.

Plant Leaves and Leaf Anatomy
Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf.Some leaves are attached to the plant stem by a petiole.Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Small green appendages usually found at the base of the petiole are known as stipules.Most leaves have a midrib, which travels the length.

Whorled Leaf Arrangement; In angiosperm anatomy, a leaf can be identified by where it emerges from the node. In a node, a leaf emerges below the axillary bud. Figure \(\PageIndex{1}\): A diagram of a node. Each node is comprised of a leaf (on the bottom) and an axillary bud (on the top, located in the axil where the petiole meets the stem).

Parts of a Leaf Diagram 1. Petiole It is the stalk that connects a leaf to the stem of the plant, it is made of complex conducting tissues called vascular tissues. Functions Providing support to the leaf and keeps it erect Transporting water and nutrients absorbed by the roots to the leaves

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.
