What is the structure of a leaf and its function?

A large surface area helps the leaf to absorb as much sunlight as possible. Leaves are thin, minimising the distance for carbon dioxide to travel into leaf cells. A midrib provides strength throughout the leaf, keeping it upright and sturdy in the wind. Chlorophyll is the green pigment that absorbs sunlight.

What are the three main structures of a leaf?

Answer: The foliage leaf consists of three parts, namely leaf base, petiole and lamina. The leaf base is also called as hypopodium. The petiole part of the leaf is also called as mesopodium. The lamina part of the leaf is called as epipodium.

What are the five parts of a leaf?

Petiole, leaf base, lamina, leaf apex, and leaf margin are the external parts of a leaf.

What are the structures of a plant?

Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on).

What are the four functions of a leaf?


  • Photosynthesis.
  • transpiration.
  • guttation.
  • storage.

What are the different parts of a leaf explain with diagram?

Most leaves have two main parts: (1) the blade and (2) the petiole, or leafstalk. The leaves of some kinds of plants also have a third part, called the stipules. The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.

What is the structure and function of plants?

Plants have two major structural systems: the root system and the shoot system. Each of these structural systems has specific roles in the function and health of the plant. The root system brings in water and nutrients from the soil, grounding the plant in the same way our feet help us balance.

What are the 4 types of leaves?

There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant.

What are the four main parts of a leaf?

Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
