Question

Transpiration provides the driving force for the movement of water from the soil to the highest leaves of plants. Transpiration is also linked to other processes in plants, including photosynthesis and the transport of mineral nutrients. Which of the following statements correctly describe(s) a relationship between transpiration and other processes in plants? Select all that apply. A. To minimize water loss during dry conditions, most plants must also restrict their ability to carry out photosynthesis. B. Open stomata provide a low-resistance pathway for CO2 to enter and for water to exit the leaf. C. The large surface area exposed to air inside the leaf maximizes the plant's ability to absorb C02 while minimizing water loss through transpiration. D. In most plants, the highest rate of transpiration occurs when the rate of photosynthesis is also highest. E. Water is pulled from the roots to the leaves by transpiration, whereas mineral nutrients diffuse from the roots to the leaves. F. Transpiration is important in cooling leaves on warm, sunny days.

Answer 1

A. To minimize water loss during dry conditions, most plants must also restrict their ability to carry out photosynthesis.

B. Open stomata provide a low-resistance pathway for CO2 to enter and for water to exit the leaf.

F. Transpiration is important in cooling leaves on warm, sunny days.

Step-by-step explanation:

Transpiration is a process of movement of water through the plant. The excess water is evaporated out from the aerial parts of the plants such as stems, leaves, and flowers.

A. To minimize water loss during dry conditions, most plants must also restrict their ability to carry out photosynthesis. : During dry conditions, the plant restricts the transpiration process by restricting the photosynthesis because in photosynthesis the water is required for synthesis of food.

B. Open stomata provide a low-resistance pathway for CO2 to enter and for water to exit the leaf.:

The stomata are the small pores on the surface of leaves which allows the gaseous exchange and loss of water. The stomata allows the entry of carbon dioxide by a low resistance pathway for obtaining as a reactant for photosynthesis.

F. Transpiration is important in cooling leaves on warm, sunny days.: The rate of transpiration becomes fast when the day is warm as the heat energy is absorbed by the plant and liberate out water to keep the leaves cool.

Answer 2

1. To minimize water loss during dry conditions, most plants must also restrict their ability to carry out photosynthesis.

2. Open stomata provide a low-resistance pathway for CO2 to enter and for water to exit the leaf.

3. In most plants, the highest rate of transpiration occurs when the rate of photosynthesis is also highest.

4. Transpiration is important in cooling leaves on warm, sunny days.

Step-by-step explanation:

Transpiration is the loss of water through evaporation and occurs via stomata of leaves. Stomata also serve as the site for the entry of CO2 for photosynthesis. Pants open the stomata to take CO2 in for photosynthesis and loose water by the process of transpiration. Therefore, a high rate of photosynthesis causes a higher rate of water loss through transpiration.

Plants found in a dry habitat close their stomata to reduce the water loss by transpiration which in turn also reduces their rate of photosynthesis. C4 and CAM pathways are adaptations of plants towards minimizing the water loss while keeping the rate of photosynthesis higher. Transpiration is required for plants to cool down their surface during hot summer days. The evaporating water absorbs the heat from the surface of leaves and the surface is cooled down.
