The correct answer is D. Entire plant’s surface.
Evaporation is the process by which water changes from a liquid to a gas or vapor. It is a natural process that occurs all around us, and it is essential for life on Earth.
Plants use evaporation to cool themselves down. When water evaporates from the leaves, it takes heat energy with it. This helps to keep the plant cool, even in hot weather.
Evaporation also helps plants to absorb nutrients from the soil. When water evaporates from the leaves, it pulls nutrients up from the roots. This helps the plant to grow and develop.
Evaporation is a vital process for plants. It helps them to cool down, absorb nutrients, and grow.
The other options are incorrect because they are not the entire plant’s surface.
- Option A: Root. The root is the part of the plant that absorbs water and nutrients from the soil. It does not participate in evaporation.
- Option B: Stem. The stem is the part of the plant that supports the leaves and flowers. It does not participate in evaporation.
- Option C: Leaf. The leaf is the part of the plant that absorbs sunlight and produces food. It is the main site of evaporation.
