ANATOMY

Detailed explanation-1: -This is because with the increase in lights, the rate of water absorption, and the resulting turgidity of the two guard cells increases. This forms the boundary of each stoma and brings about the opening of the stomates, which increases the transpiration rate.

Detailed explanation-2: -Water stress, high temperatures, and high carbon dioxide concentration causes stomata to close.

Detailed explanation-3: -Increased humidity has a reduces transpiration. The lower the humidity the easier it is for the plant to release water. The type of plant is also a factor in how much a plant will transpire. For example plants grow in arid hot areas such as the desert will transpire less as they aim to conserve water.

Detailed explanation-4: -Photosynthesis occurs during the day and thus stomata are open to supply the carbon dioxide required for the process. The stomatal openings remain closed at night as photosynthesis is not conducted without sunlight. They are closed to prevent water loss via the stomatal pores.

Detailed explanation-5: -Transpiration is the process of evaporation of water through aerial parts of the plant. The rate is high when the soil is wet and the air is dry. More items
