  1. Chapter 1 Lesson 5 Food Making

  2. Words to Know • Photosynthesis- the process by which plants produce food. • Chlorophyll- the green matter in plants that traps light used to produce food.

  3. Food Making ingredients • Plants need three things to make food. • Carbon dioxide- which enters the plants through the stomates. • Water- which enters the plant through tubes from the roots to the stems into the leaves. • Light- which gets trapped in the leaves by chlorophyll

  4. The Food Making Process • 1. light is trapped by the chlorophyll in the leaf, and water is carried to the leaf by tubes. • 2. inside the leaf the light breaks down water into hydrogen and oxygen, and carbon dioxide enters through the stomates. • 3. the hydrogen and carbon dioxide combine to make food and the oxygen leaves through the stomates.
