Plant can respire in :a)Darkb)Lightc)Both in light and darkd)MorningCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Respiration is constitutive process that occurs in all tissues. Unlike photosynthesis that can happen only in the presence of sunlight, respiration in plant occurs all time. So, the answer is - both light and dark.

Answer

Plant Respiration

Plant respiration is the process by which plants take in oxygen and release carbon dioxide, just like animals do. It is an essential process for the survival of plants as it provides them with the energy they need to carry out various metabolic activities. Unlike animals, however, plants also undergo photosynthesis, which is the process by which they convert sunlight into energy.

Respiration in the Dark

Plants are capable of respiration even in the absence of light. In fact, respiration is an ongoing process in plants that occurs 24 hours a day. During respiration, plants absorb oxygen and release carbon dioxide. This process takes place in the mitochondria of plant cells. The energy produced through respiration is used for various metabolic activities, such as growth, repair, and reproduction.

Respiration in the Light

Plants also respire in the presence of light. However, during photosynthesis, plants produce more oxygen than they consume. This surplus oxygen is released into the atmosphere through tiny pores on the leaves called stomata. At the same time, carbon dioxide is taken in through the stomata for photosynthesis. While photosynthesis primarily occurs during the day, respiration continues to take place simultaneously.

Respiration in Light and Dark

Plants carry out respiration both in the light and in the dark. During the day, respiration occurs alongside photosynthesis, with the plant taking in oxygen and releasing carbon dioxide. This is because photosynthesis provides the plant with energy in the form of glucose, which is then broken down through respiration to release energy for other cellular processes.

In the absence of light, plants continue to respire. However, since photosynthesis cannot take place without light, the plant does not produce glucose. Instead, it relies on stored energy reserves, such as starch, which are broken down through respiration to release energy.

Conclusion

Plants respire in both light and dark conditions. Respiration is a continuous process that provides plants with the energy they need for growth and other metabolic activities. While photosynthesis occurs mainly during the day and produces surplus oxygen, respiration ensures a constant supply of energy for the plant's survival.
