Question

The water lost during transpiration is a side effect of the plant’s exchange of gases. However, the plant derives some benefit from this water loss in the form of _____. aa. increased turgor and increased growth b. increased growth and metabolic c. heating evaporative cooling and metabolic d. heating evaporative cooling and mineral transport

Answer 1

Answer:

The correct answer is

d. heating evaporative cooling and mineral transport

Explanation:

Plants transpire to expel excess heat energy by a process known as evaporative cooling. As the water involved in transpiration evaporates, heat energy is transferred from the plant system into the surrounding environment cooling down the plant.

During transpiration, the stomata of the plant are open allowing the outward flow of the evaporated water and also the open stomata enable the plant to absorb carbon dioxide (CO2) from the atmosphere. The carbon dioxide is required in photosynthesis for the formation glucose while producing oxygen as well.

The water also transports nutrients dissolved in it as it is being transported to the leafs for evaporation. These nutrients are thus delivered tm all parts of the plant.
