Plants form organic matter from water and carbon dioxide in the presence of sunlight and release oxygen, a process known as photosynthesis. The energy required to carry out chemical reactions in plants is obtained from sunlight. This energy is stored by sunlight by a green component called chlorophyll found in the leaves of plants. However, this energy can also damage plant leaves but plants protect themselves from heat damage by sunlight. Let's know more about Photosynthesis Quiz.
