What happens inside a leaf?
|
A leaf has tiny holes on its underside. Through these holes it takes up carbon dioxide, which is present in the air. Water, sucked up by the plant's roots, is also sent to the leaf. In the leaf the carbon dioxide and the water are combined together to make sugar. The energy to drive this process is provided by sunlight. | | A leaf is a factory that manufactures sugar. |
