Cells have chloroplasts. The green chlorophyll traps light energy.

Cells have chloroplasts. The green chlorophyll traps light energy. This is the inside of a leaf. The top cells have many chloroplasts and no gaps. Air spaces let gases move around. Veins bring water to the cells. Thin, flat leaves catch light. They have a large surface area.
