Parts of a Leaf YouTube
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.

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.

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?

A leaf is made of many layers that are sandwiched between two layers of tough skin cells (called the epidermis). The epidermis also secretes a waxy substance called the cuticle. These layers protect the leaf from insects, bacteria, and other pests. Among the epidermal cells are pairs of sausage-shaped guard cells.

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.

Plant Leaves and Leaf Anatomy
There's more to a leaf than meets the eye. Can you identify the functions of each of the labeled structures in the diagram? A leaf consists of several different kinds of specialized tissues that work together to make food by photosynthesis. The major tissues are mesophyll, veins, and epidermis. Mesophyll makes up most of the leaf's interior.

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.

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.
