Plants need sunlight because plants use the Sun to make food. Chlorophyll helps plants collect the sunlight. Chlorophyll is made up of even smaller parts called Chloroplasts. Chloroplasts have a green color to them. Leaves have Chloroplast because they help the plant or tree collect sunlight and turn it into sugar. That process is called photosynthesis. Chloroplasts are basically the tiny parts of cells that produce the plant’s food. Plants also need Carbon dioxide, water, and nutrients to survive. The plant makes Oxygen gas and sugar as the food! Plants have evolved a way to feed themesleves!
