Question

Which of the following about plants is correct?
1. Respiration and photosynthesis proceed at the same rate
2. Photosynthesis proceeds at a much faster rate than respiration
3. Photosynthesis proceeds at a much slower rate than respiration
4. There is no connection between the respiration and photosynthesis

Answer 1

Correct Answer - Option 2 : Photosynthesis proceeds at a much faster rate than respiration

The correct answer is Photosynthesis proceeds at a much faster rate than respiration.

• In plants, photosynthesis proceeds at a much faster rate than respiration.
• Plants perform both respiration and photosynthesis.
• In respiration, plants use oxygen to convert food into energy.
• In photosynthesis, plants produce oxygen as a by-product.
• Still, plants give way more oxygen because the rate of photosynthesis is much faster than that of respiration.

• Photosynthesis
  • It is a process by which plants make food.
  • Chlorophyll, a pigment in green leaves absorbs sunlight.
  • Carbon dioxide + water + [light energy] → oxygen + glucose.
  • The chemical equation:-  6CO₂ + 6H₂O + [light energy] → 6O₂ + C₆H₁₂O₆.
  • It happens only in Sunlight.
• In many ways, respiration is the opposite of photosynthesis.
  • The respiration in plants involves using the glucose produced during photosynthesis plus oxygen to produce energy.
  • Equation of chemical reaction:- C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 32 ATP (energy).
  • It happens 24 hours a day.
