The correct answer is a and c.Explanation:Transpiration is the phenomenon of the loss of water in the form of vapor from the living tissues of aerial parts of the plant. Water lost is pure water solutes.The process of transpiration is carried out by the special structures found in the leaves of plants called stomata. It occurs mainly through stomata.It is both a physical and physiological process.Water molecules in the plant tissues are removed from the aerial parts of the plants during transpiration. Plants only use a small portion of the water they absorb for growth and development. The rest is eliminated in the form of transpiration.The rate of transpiration depends on several external factors like humidity, temperature, sunlight, atmospheric pressure, and wind speed. The water released by transpiration is carried away faster as the wind blows faster. As a result, the rate of transpiration increases as the wind speed increases.A leaf with a larger surface area will have a higher transpiration rate than one with a smaller surface area. As a result, an increase in leaf area leads to an increase in transpiration rate.Additional InformationMinimum transpiration is found in succulent xerophytes.Maximum transpiration occurs in mesophytes.
