Which part of the plant is green in color?

The part of the plant that is green in color is the leaf. Leaves are green because they contain a substance called chlorophyll. This green pigment helps the plant make food using sunlight, water, and carbon dioxide. This process is called photosynthesis. Leaves are often called the “kitchen of the plant” because food is prepared inside them. Apart from making food, leaves also help the plant to breathe by taking in carbon dioxide and releasing oxygen. Some leaves are small, some are big, and they come in many shapes, but almost all are green due to chlorophyll.
