Which of the following factors has the greatest influence on the rate of transpiration?

• Temperature
• Light intensity
• Air humidity
• Wind movement

Increasing the light intensity will decrease the rate of transpiration.

What is the primary mechanism that drives the movement of water from roots to leaves during transpiration?

• Cohesion-tension theory

What is the purpose of conducting a 'humid temperature' experiment in the study of transpiration?

• To study the effect of temperature on transpiration without the influence of humidity
• To study the effect of humidity on transpiration without the influence of temperature
• To study the combined effect of temperature and humidity on transpiration
• There is no such experiment in the study of transpiration

Increasing wind movement will decrease the rate of transpiration in plants.

What is the primary function of transpiration in plants?

• Water and nutrient transport

What is the purpose of using a 'potometer' in transpiration experiments?

• To measure the rate of transpiration
• To control the temperature
• To control the humidity
• To measure the photosynthetic rate

Increasing the humidity of the surrounding air will increase the rate of transpiration in plants.

What is the primary mechanism that enables the movement of water from roots to leaves during transpiration?

• Cohesion-tension theory

What happens to a plant if the rate of transpiration becomes excessively high?

• The plant will wilt
• The plant's growth will increase
• The plant will absorb more water and nutrients
• There will be no effect on the plant
