What is photosynthesis and Cellular respiration in a paragraph?

Photosynthesis is a process in which plants use water , carbon dioxide and minerals  to create their food ( that is oxygen and energy-rich organic compounds) . Through this process oxygen is released into the air.

An example  is how plants convert sugar and energy from water, air and sunlight into energy to grow.

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. It is a set of metabolic reactions and processes that take place in the cells of organisms. This process involves glucose and oxygen reacting to form carbon dioxide and water.
