Answer:
The correct answer is -
1. photosynthesis and cellular respiration
2. glucose and cellular respiration
3. O2
4. C6H12O6
5. CO2
6. H2O
Explanation:
For the survival and growth of a plant, there are several functions and structure are essential but two most important parts are photosynthesis that provides food and glucose for the plant and its nourishment and other is cellular respiration which is required to convert glucose into ATP a form of energy.
In animals, photosynthesis is not possible so they depend on the plants and other sources for glucose and another important process for growth and survival is cellular respiration.
The chemical formula of oxygen, glucose, carbon dioxide, and water is as follow:
3. O2 - oxygen
4. C6H12O6 - glucose
5. CO2 - carbon dioxide
6. H2O - water
