Question

answer the following questions
1. Write the chemical equations which represent the aerobic and anaerobic respiration,
2. How can we say that respiration and photosynthesis are complementary to each other?
3. How do the roots absorb oxygen from the soil?​

Answer 1

Answer:

1.Aerobic respiration takes place in the mitochondria and needs oxygen and glucose, and generates carbon dioxide, water, and energy. Thechemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water). Anaerobic respiration takes place in the cell cytoplasm and produces lactic acid.

2.Photosynthesis and cellularrespiration are complementary processes by which living things obtain needed substances. They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in differentways.

3.The roots of a plant take up air from the spaces between the soil particles. Root hairs are in contact with the air in the soil particles.Oxygen from the air in soil particles diffuse into root hair and reach all the cells of theroot where it is utilised in respiration.
