Apex: tip of the leaf • Margin: edge of the leaf • Veins: carry food/water throughout leaf; act as a structure support • Midrib: thick, large single vein along the midline of the leaf • Base: bottom of the leaf • Petiole: the stalk that joins a leaf to the stem; leafstalk • Stipule: the small, leaf-like appendage to a …
What are the 5 main parts of a leaf?

What are the 8 layers of a leaf?
2 8. List the layers of the leaf starting at the upper cuticle all the way to the lower cuticle. Cuticle, upper epidermis, palisade mesophyll, spongy mesophyll, lower epidermis, cuticle. or to storage areas in the plant.
What is the basic structure of a leaf?
Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.
What are the 10 internal parts of the leaf?
The anatomy or internal structure of dicot leaves can be understood on the basis of the following structures:
- Upper Epidermis.
- Mesophyll. a. Palisade Tissue. b. Spongy Tissue.
- Vascular Tissue.
- Midrib.
- Lower Epidermis.
What are the different parts of 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 are the names of the layers in a leaf?
A cross section through the blade of a typical dicot leaf reveals 4 distinct tissue layers.
- Upper epidermis. This is a single layer of cells containing few or no chloroplasts.
- Palisade layer.
- Spongy layer.
- Lower epidermis.
What are the functions of the parts of a leaf?
The mesophyll is found between the upper and lower epidermis; it aids in gas exchange and photosynthesis via chloroplasts. The xylem transports water and minerals to the leaves; the phloem transports the photosynthetic products to the other parts of the plant.
What are the different parts of a leaf explain with diagram?
The different parts of a leaf are as follows: (i) Petiole : The leaf is attached to the stem by means of a short stalk called petiole. (ii) Lamina : The flat green, expanded portion of the leaf is called leaf-blade or lamina. (iii) Leaf base: The end of the lamina joining the petiole is called leaf base.
