What is Transpiration?

Transpiration is the process through which plants absorb water from the soil and release it into the atmosphere through their leaves.

How Does Transpiration Work?

Water is absorbed by the plant's roots and transported to the leaves through the xylem. Once in the leaves, water evaporates and exits the plant through small openings called stomata.

Factors Affecting Transpiration

• Temperature: Higher temperatures lead to increased transpiration rates.
• Humidity: Lower humidity levels result in higher transpiration rates.
• Wind: Increased air movement can enhance transpiration.
• Light: Intense light can stimulate stomatal opening, increasing transpiration.

Functions of Transpiration

Transpiration helps to transport water and nutrients from the roots to the rest of the plant. It also cools the plant and maintains its structure and turgidity.

Transpiration and the Water Cycle

Transpiration plays a significant role in the water cycle, as it contributes to the movement of water from the soil to the atmosphere. This water vapor eventually condenses to form clouds and precipitates as rain.

Importance of Transpiration

Transpiration is essential for the overall health and survival of plants. It helps in nutrient uptake, temperature regulation, and the maintenance of turgor pressure in plant cells.
