Detailed explanation-1: -False. Hint: Plants perform photosynthesis in leaves to make their own food. They require carbon dioxide, water and sunlight to perform this process.
Detailed explanation-2: -While plants can absorb water through their leaves, it is not a very efficient way for plants to take up water. If water condenses on the leaf during high humidity, such as fog, then plants can take in some of that surface water. The bulk of water uptake by most plants is via the roots.
Detailed explanation-3: -Plants, like animals, take in oxygen and give out carbon dioxide during respiration. Only during photosynthesis, plants take in carbon dioxide and release oxygen as a byproduct.
Detailed explanation-4: -The correct option is A True. Transpiration: It is a biological process of water loss in the form of water vapor from the stomatal openings on the aerial parts of the plant. It does not occur at night because the stomata remain closed during the night.
Detailed explanation-5: -(e) False. Transpiration is the loss of water from the aerial parts of the plant.
