FAQs on Do All Organisms Respire Video Lecture - Crash Course for Class 6

1. What is respiration in organisms?
Ans.Respiration is a biological process through which organisms convert food into energy. It involves the intake of oxygen and the release of carbon dioxide. This process is essential for growth, reproduction, and maintaining the overall functioning of cells.
2. Do all organisms respire in the same way?
Ans.No, not all organisms respire in the same way. While most animals and plants use aerobic respiration, which requires oxygen, some organisms like bacteria and yeast can perform anaerobic respiration, which does not need oxygen and produces less energy.
3. Why is respiration important for organisms?
Ans.Respiration is crucial because it provides energy needed for various life processes, such as movement, growth, and repair of tissues. Without respiration, organisms would not be able to sustain their life functions.
4. Can plants respire?
Ans.Yes, plants do respire. They respire both during the day and night. During the day, they perform photosynthesis, which produces oxygen, but they also take in oxygen for respiration to release energy for their growth and development.
5. What are the by-products of respiration?
Ans.The main by-products of respiration are carbon dioxide and water. In aerobic respiration, glucose is broken down with the help of oxygen to release energy, while in anaerobic respiration, different by-products like alcohol or lactic acid may be produced, depending on the organism.
