Functions of Leaf
Below mentioned are few functions performed by leaves of a plant-
- Photosynthesis:
- Leaves capture sunlight to convert carbon dioxide and water into glucose and oxygen in chloroplasts, sustaining life on Earth.
- Transpiration:
- Leaves regulate plant water balance by evaporating water from their surfaces, creating negative pressure in xylem vessels to pull water and nutrients from roots.
- Guttation:
- Excess water is removed from leaf edges as water drops when stomata are closed.
- Gas Exchange:
- Stomata openings regulate gas exchange, allowing carbon dioxide in for photosynthesis and releasing oxygen, essential for plant metabolism and atmospheric balance.
- Storage:
- Succulent plant leaves store water and nutrients, aiding survival in arid environments and regions with water scarcity.
- Protection:
- Specialized structures like trichomes and thorns defend against physical damage by herbivores and pathogens, enhancing plant survival in various ecological niches.
Diagram of Leaf and Label its Parts
The leaf diagram shows the structure of a leaf, including the blade, veins, and petiole, helping us understand how plants exchange gases and nutrients. Plants play a crucial role as they provide oxygen and shelter, and are a food source for the life on Earth.
The leaf diagram class 6 and class 10 provide a basic understanding of the structure of leaves and plants. The leaf diagram with labels shows different parts which helps us learn about processes like photosynthesis and transpiration.
