Why Do Plants Need Sunlight to Live?
Plants need sunlight to complete photosynthesis, which is the process by which plants convert water, carbon dioxide and light to oxygen and energy. This energy is in the form of sugar. In addition to providing nutrition for the plant, photosynthesis creates oxygen that humans and other animals need to breathe. It also indirectly provides nutrition to any animals that feed on the plant. Does this Spark an idea?

Chloroplasts are where the main work of photosynthesis occurs. Chloroplasts contain the following structures: outer and inner membranes, stroma and thylakoids. Thylakoids contain chlorophyll.
Mesophyll Cells

A plant's chloroplasts are inside the mesophyll cells. Mesophyll cells are usually inside the leaf. The epidermal cells coat the top and bottom of the leaf and protect the mesophyll cells.

Why Are Plants Green?
-
Plants are green because during photosynthesis the chloroplasts cannot absorb the green light that comes from the sun, though they absorb blue and red light. The green light is reflected back and makes the plant appear green.
