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.

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.


Leaves Biology for Majors II

Like the stem, the leaf contains vascular bundles composed of xylem and phloem (Figure 3.4.2.6 − 7 3.4.2. 6 − 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.

Leaf Parts. Leaves are generally composed of a few main parts: the blade and the petiole. Figure 13.1.2 13.1. 2: A leaf is usually composed of a blade and a petiole. The blade is most frequently the flat, photosynthetic part. The petiole is a stem that attaches the leaf blade to the main stem of the plant.

Read the plant definitions below, then label the simple leaf morphology diagram below. axil - the angle between the upper side of the stem and a leaf or petiole. lamina - the blade of a leaf. leaf apex - the outer end of a leaf; the end that is opposite the petiole. midrib - the central rib of a leaf - it is usually continuous with the petiole.

Plant Leaves and Leaf Anatomy

leaf, in botany, any usually flattened green outgrowth from the stem of a vascular plant. As the primary sites of photosynthesis, leaves manufacture food for plants, which in turn ultimately nourish and sustain all land animals. Botanically, leaves are an integral part of the stem system.

Help your learners identify the various parts of a leaf with this handy activity. It includes a labelled poster, which could also be displayed on your classroom wall. Students use this to label their own blank leaf diagram. What are the parts of a leaf? - Blade - Tip - Petiole - Midrib - Vein - Margin - Stipules. How will this activity be useful?

1. What is the Leaf Cross Section? Leaves are the powerhouse of plants as they prepare food by the process of photosynthesis. In the presence of water and carbon dioxide, the chlorophyll present in the leaves converts the energy of the sunlight into sucrose and water. The structure of the leaves helps in the regulation of the whole process.

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 manu­factures food for the whole plant.

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.
