In the case of plants, photosynthesis and cellular respiration are reactions that complement each other. In fact, it could be said that in both cases it is the same process, but in the opposite direction. Difference b/w Photosynthesis and Cellular Respiration
In this sense, we know that you need more information to complete your task; although it is also possible that you are simply curious about this topic. The important thing is that whatever the case, if you continue reading you will find the answers you are looking for about the difference between cellular respiration and photosynthesis.
PHOTOSYNTHESIS Difference b/w Photosynthesis and Cellular Respiration
It is a photoautotrophic process by which plants feed on and convert carbon dioxide into organic compounds and oxygen.
Photosynthesis requires sunlight to take place. Ultraviolet rays excite electrons when they come into contact with chlorophyll, thus causing a separation of oxygen molecules from carbon dioxide. when it happens they become a source of food.
Photosynthesis takes place in the chloroplasts and organelles of plant cells.
In case you still had doubts, yes, silvers also breathe and they do so thanks to their leaves. In addition to feeding, plants need to breathe and in them the process of respiration results in the opposite of photosynthesis: glucose and oxygen are converted into carbon dioxide and water.
Unlike photosynthesis, cellular respiration does not require the constant presence of sunlight, in addition, it occurs all the time; while photosynthesis occurs every so often.
Another difference between photosynthesis and cellular respiration is that the former is an endothermic reaction, while the latter is exothermic. Likewise, for cellular respiration to occur, the presence of catalysts is not necessary; as in the case of photosynthesis where the reaction only occurs in the presence of chlorophyll.
Finally, cellular respiration takes place in the cytoplasm and mitochondria of cells.
Key differences between photosynthesis and cellular respiration
- Photosynthesis releases oxygen and other organic compounds, while cellular respiration releases carbon dioxide and water.
- The first one is an endothermic process (requires energy), while the second one is an exothermic process (releases energy).
- Photosynthesis does not happen all the time, whereas cellular respiration does.
- For photosynthesis to occur, the presence of a catalyst (chlorophyll) is necessary, while in the process of cellular respiration, catalysts are not necessary.
