Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Energy is also transformed from one type to another. Describe what happens to these four substances, light energy, and chemical energy during photosynthesis. Then write a simple equation for the substances and another for energy, using words and arrows to illustrate these changes.

During photosynthesis, plants use light energy from the sun to transform water and carbon dioxide into glucose (a sugar) and oxygen. This process takes place in the chloroplasts of plant cells and is critical to the survival of both plants and many other organisms that rely on plants as a food source.

The light energy from the sun is captured by chlorophyll, a pigment in the chloroplasts. This energy is used to split water molecules into oxygen and hydrogen ions. The oxygen is released into the atmosphere, while the hydrogen ions are used to power the production of ATP, a form of chemical energy that the plant can use.

At the same time, carbon dioxide from the atmosphere is taken in by the plant and combined with the hydrogen ions to produce glucose, a type of sugar that can be stored for later use.

The overall chemical equation for photosynthesis can be written as:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

This equation shows that six molecules of carbon dioxide and six molecules of water are combined using light energy to produce one molecule of glucose and six molecules of oxygen.

In summary, during photosynthesis, light energy is converted into chemical energy in the form of glucose, using water and carbon dioxide as raw materials. Oxygen is also produced and released into the atmosphere as a byproduct of this process.
