Photosynthesis is a process in which a plant uses energy from the sun, water, and carbon dioxide to produce sugar, and oxygen.
THE PROCESS OF PHOTOSYNTHESIS
Water is absorbed from the soil into the cells of root hairs. The water passes from the roots to the xylem vessels in the stem until it reaches the leaves.
Carbon dioxide is absorbed from the air through the leaves called stomata. The leaves also contain chloroplasts which hold chlorophyll. The sun’s energy is captured by the chlorophyll.
Plants take carbon dioxide, water, and light energy to make glucose and oxygen. They then give off some oxygen and use the sugar.
THE PROCESS OF CELLULAR RESPIRATION
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae.
DRAWINGS OF PHOTOSYNTHESIS
The roots take in water, and the leaves take in sunlight. The roots take water in from the ground, and the leaves absorb the light energy from the atmosphere.

We breathe in oxygen, and the oxygen circulates in our lungs it turns into carbon dioxide which we breathe out.
