Teaching the Kid: Photosynthesis and Respiration

What Is Photosynthesis For Kids Facts & Information


Apart from the food they manufacture, plants also need carbon, hydrogen and oxygen to survive. Water absorbed from the soil provides the hydrogen and oxygen. During photosynthesis, carbon and water are used to synthesize food. They also need nitrate to make amino acids (Amino acid an ingredient for making protein). In addition to that, they need magnesium to make chlorophyll.

In this lesson, we shall learn more about how plants manufacture food (photosynthesis), and learn more about the conditions that must be present for this to happen.

The simple story of photosynthesis and cellular respiration

Every living creature needs food or energy to survive. Some depend on others for food and energy, whiles others can produce their own food.

Plants make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise.

Photosynthesis and respiration go hand in hand. The result of photosynthesis is glucose, which is stored as chemical energy in the plant cells.
This stored chemical energy comes from the conversion of inorganic carbon (carbon dioxide) into organic carbon. Respiration releases the stored chemical energy.

Many fish have gills but some fish, all amphibians, reptiles, birds and mammals have lungs. The development of lungs in higher vertebrates is an important adaptation for the dry terrestrial environment. Compared to gills and the respiratory systems of invertebrates, lungs provide a larger surface-to-volume ratio.
