  • How do plants make their own food by photosynthesis?

  • In addition to this plants need sunlight for photosynthesis to occur and there is no sunlight in the night so a plant can use aerobic respiration to produce oxygen and get energy.On the other hand humans can actively hunt for food so we do not need 2 chemical reaction to have energy. Plants make their own food by photosynthesis.

  • What resources do plants use to produce energy?

  • Plants use these resources they have produced from photosynthesis and respiration to grow, flower, seed, or produce fruit which is another form of plant seed. What would happen to the world if plants could not produce energy?

  • Why do plants respire all the time?

  • Plants respire all the time because their cells need energy to stay alive, but plants can only photosynthesize when they are in the light. The diagrams summarizes what this means for the overall release of carbon dioxide or oxygen from plants.

  • How can a plant use glucose to increase biomass?

  • The plant can use glucose to increase it biomass. i.e. to grow. Photosynthesis happens in the green bits of every plant but mainly in the leaves. Chlorophyll absorbs sunlight and uses its energy to convert carbon dioxide and water into glucose. Oxygen is also produced.
