What is the morphology of a leaf?

What is the morphology of a leaf?

Generally, leaf base, petiole, and lamina, together form the main parts of a leaf. Leaf Base: This is the part where a leaf attaches to the stem. Leaf base has two small leaf-like structure called stipules. In plants like paddy, wheat, and other monocotyledons, this leaf base is wide and masks the stem.

What is the external structure of a leaf?

Leaf Structure and Function. The outermost layer of the leaf is the epidermis. It consists of the upper and lower epidermis, which are present on either side of the leaf. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis).

What are the external features of plant?

Plants have external parts that help them grow, survive and reproduce. These parts include the stem, leaves, flower, fruits and roots.

What are storage leaves?

Leaves of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or storage of water, such as the storage leaves found in bulbs.

What is the function of the leaf in plant morphology?

Leaf function The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

What is the external function of a leaf?

Functions of a Leaf Photosynthesis: This is the most important function of a leaf. They contain chloroplasts which have the pigment chlorophyll that is responsible for helping in photosynthesis. The prepared food is transported to the other parts of the plant via phloem tissue.

How is the external structure of a leaf adapted for photosynthesis?

Leaves have a large surface area so more light hits them. The upper epidermis of the leaf is transparent, allowing light to enter the leaf. The palisade cells contain many chloroplasts which allow light to be converted into energy by the leaf.

What are the external parts of a leaf and their functions?

Epidermis: It is the outermost layer and secretes a waxy substance called the cuticle. The cuticle helps retain water inside the leaf cells. The epidermis houses the guard cells which regulate the movement of water into and outside the cell. Guard cells do so by controlling the size of the pores also called stomata.

What is the external structure of plants?

External plant structures such as leaves, stems, roots, flowers, fruits, and seeds are known as plant organs. These structures can be divided into two groups: sexual reproductive and vegetative.
