FAQs on Detailed Overview: Respiration in Plants Video Lecture - Biology for JAMB

1. What is respiration in plants?

Ans. Respiration in plants is the process by which they convert stored energy into usable forms. It involves the breakdown of glucose molecules to release energy, which is then used for various cellular activities.

2. How do plants obtain oxygen for respiration?

Ans. Plants obtain oxygen for respiration through tiny pores called stomata, which are present on the surface of leaves and stems. These stomata allow the exchange of gases between the plant and the environment, enabling the intake of oxygen.

3. What is the role of mitochondria in plant respiration?

Ans. Mitochondria are the powerhouses of plant cells and play a crucial role in respiration. They are responsible for carrying out the chemical reactions that convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate).

4. How does the rate of respiration in plants vary with temperature?

Ans. The rate of respiration in plants generally increases with an increase in temperature. Warmer temperatures provide more energy for the enzymatic reactions involved in respiration, leading to a higher rate of glucose breakdown and energy release.

5. Can plants respire without sunlight?

Ans. Yes, plants can respire without sunlight. While photosynthesis, which produces glucose, requires sunlight, respiration can occur in the absence of light. Respiration is an essential process for plants to release energy even during periods of darkness or when light is unavailable.
