Plants use light energy to put together carbon dioxide and water to make their own food
Leaves help plants live. NOt only do the carry on photosynthesis but they breathe. How does a leaf breathe?
The leaves have tiny holes on them that allow water vapor and gases to escape from the plant and allow carbon dioxide to enter the plant. As the sun heats a leaf, it causes water to become a gas, or water vapor.
