4 Identify What are the starting materials and products of photosynthesis and cellular
respiration?

Detail is given below.

Explanation:

Photosynthesis:

Reactants =   Carbon dioxide + water + energy

Products =    glucose + oxygen

Chemical equation:

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

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Cellular respiration:

Reactants =  Glucose + oxygen

Products =  carbon dioxide + water + 38ATP

Chemical equation:

Glucose + oxygen → carbon dioxide + water + 38ATP

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
