Leaf Structure and Function

A leaf is a flattened, photosynthetic structure of vascular plants, primarily composed of a blade and petiole, that facilitates gas exchange and light absorption for the process of photosynthesis. Its structure, including chloroplasts, stomata, and vascular tissues, supports its functions in energy production, transpiration, and nutrient transport.

Overview

Leaves are essential organs of plants, primarily responsible for photosynthesis, where they convert sunlight into energy. They consist of various structures, including the blade, petiole, and veins, each serving specific functions that contribute to the plant's overall health and growth. Through pro...

Key Terms

Photosynthesis
The process by which green plants use sunlight to synthesize foods from carbon dioxide and water.

Example: Plants convert sunlight into energy through photosynthesis.

Stomata
Tiny openings on the leaf surface that allow for gas exchange.

Example: Stomata open to let in carbon dioxide for photosynthesis.

Chlorophyll
The green pigment in plants that absorbs light energy for photosynthesis.

Example: Chlorophyll gives leaves their green color.

Transpiration
The process of water vapor loss from plant leaves.

Example: Transpiration helps cool the plant and maintain nutrient flow.

Veins
The vascular structures in leaves that transport water and nutrients.

Example: Veins help distribute water throughout the leaf.

Blade
The flat part of the leaf that captures sunlight.

Example: The blade of the leaf is where most photosynthesis occurs.
