You know that all living organisms respire in order to release energy from glucose and make it available in the form of adenosine triphosphate for chemical, osmotic and other work.

Plants are no exception. They need to respire virtually all the time in order to supply their energy needs. They are not able to use the adenosine triphosphate generated in photosynthesis for these purposes.

Plants respire in the normal way using glycolysis, Krebs cycle, oxidative phosphorylation etc

Often, the respiration is masked by the fact that photosynthesis produces oxygen faster than respiration takes it up and photosynthesis uses carbon dioxide faster than respiration produces it. It is only in the dark that the full effects of respiration become apparent when photosynthesis is brought to a halt.

Plants respire to break down sugars produced during photosynthesis to release energy for metabolism and growth. This process involves taking in oxygen and giving off carbon dioxide, similar to respiration in animals.

Do both animals and plants respire?

Yes, both animals and plants respire to release energy stored in food. Animals breathe in oxygen and exhale carbon dioxide through a process called cellular respiration. Plants use photosynthesis to convert sunlight into energy, and also respire by taking in oxygen and releasing carbon dioxide.


Do plant cells respire?

Yes, plant cells do respire. Cellular respiration in plants involves the breakdown of glucose to release energy, which is used for various cellular activities. While plants also undergo photosynthesis to produce their own food, they still need to respire to obtain energy from the stored sugars.


Names of some plants which respire anaerobically?

Some examples of plants that can respire anaerobically include rice plants, mangrove trees, and water lilies. These plants have adaptations to survive in waterlogged or flooded environments where oxygen availability is limited.


When plants respire do they take up oxygen from their roots or from the stomata in their leaves or both?

Plants primarily take up oxygen through their stomata in the leaves during respiration. Oxygen is required for the breakdown of glucose to release energy. While roots also respire, it is mainly to break down nutrients and not primarily for oxygen uptake.


Do plants respire and how?

Great question! Not as we do, with lungs. which is an active process, but they do breathe by a passive process. Both plants and animals carry on a process called respiration which occurs on a cellular level and involves an exchange of oxygen and carbon dioxide. Plants mostly do this in their leaves, which in some ways are similar to our skin (which, incidentally, is the largest organ in our bodies). The process by which all respiration takes place is called diffusion - plants 'breathe' through their leaves - the really cool thing is that they 'exhale' - ready? oxygen...which is why we want trees - because they breathe by 'inhaling' carbon dioxide and 'exhaling' oxygen for us to use in our bodies to do our own respiration.BTW - Animals breathe differently than plants. We do it in two places, in our lungs - as most people are aware - and also in our body tissues. Our lungs take in oxygen (that came from the plants respiration) and we put it in our blood, and at the same time release the carbon dioxide from the blood and put it into the atmosphere so the plants can use it. In addition, we also have a second type of breathing that occurs in all our bodies called tissue respiration. In our tissues, we take the oxygen from the blood and put it in the tissues, and at the same time take the carbon dioxide from the tissues and put it in the blood to be taken to the lungs.

The waste gas produced by plants as they respire is oxygen. This is why plants are very important to the earth. Without plants, there probably would not be enough oxygen in the air for all to breathe.
