Question

Why do green plants need sunlight to perform photosynthesis?

Answer 1

Plants make their own food by combining a gas called carbon dioxide, which they get from the air, with water from the soil. This process is called photosynthesis. To power the process, the plant uses the energy of sunlight. A green pigment in the leaves called chlorophyll traps the Sun's energy.

Answer 2

Plants need sunlight for a process that we call photosynthesis.That chlorophyll absorbs the sunlight and excites electrons, and the electron is what is used to create the sugars or food for the plant. Some plants don't contain chlorophyll
