What is the definition of transpiration?

• Transpiration is the process of nutrient absorption in roots.

• Transpiration is the process of water movement through a plant and its evaporation from aerial parts, primarily from the leaves.

• Transpiration refers to the photosynthesis process in plants.

• Transpiration is the movement of carbon dioxide into the plant.

How does transpiration help in cooling plants?

• Transpiration cools plants by releasing water vapor, which absorbs heat during evaporation.

• Transpiration increases soil moisture, which cools the roots.

• Transpiration helps plants absorb more sunlight, leading to cooling.

• Transpiration releases carbon dioxide, which lowers plant temperature.

What role does sunlight play in transpiration?

• Sunlight absorbs water from the soil for plants.

• Sunlight cools the leaves, reducing water loss.

• Sunlight increases the amount of nutrients in the soil.

• Sunlight drives the evaporation of water from plant leaves, enabling transpiration.

Name one factor that increases the rate of transpiration.

• Higher temperature

• Low humidity

• Increased soil moisture

• Reduced light intensity

How does humidity affect transpiration rates?

• Humidity does not influence plant water loss.

• Low humidity has no effect on transpiration rates.

• High humidity decreases transpiration rates, while low humidity increases them.

• High humidity increases transpiration rates.

What is the relationship between temperature and transpiration?

• Higher temperatures typically increase the rate of transpiration.

• Higher humidity decreases transpiration rates.

• Lower temperatures increase transpiration rates.

• Transpiration is unaffected by temperature changes.

Why is transpiration important for nutrient transport in plants?

• Transpiration primarily helps in photosynthesis by absorbing sunlight.

• Transpiration reduces water loss and prevents plant wilting.

• Transpiration is mainly responsible for gas exchange in leaves.

• Transpiration is crucial for nutrient transport as it generates the necessary pressure to move water and nutrients from roots to leaves.

How do wind conditions influence transpiration?

• Wind decreases transpiration by trapping moisture around leaves.

• Wind increases transpiration by enhancing water vapor removal from leaves.

• Wind has no effect on transpiration rates in plants.

• Wind only influences transpiration during the night.

What part of the plant is primarily responsible for transpiration?

• Leaves

• Roots

• Flowers

• Stems

How does soil moisture affect transpiration?

• Soil moisture directly influences the rate of transpiration in plants.

• Soil moisture has no effect on transpiration rates.

• Higher soil moisture decreases transpiration in all plants.

• Transpiration is solely dependent on temperature, not soil moisture.
