Question

Please answer these two​

Answer 1

Answer:

5. The carbon dioxide required for photosynthesis is taken through stomata. So, even if a plant keeps on taking in oxygen and releasing carbon dioxide during the day, it does not mean that no photosynthesis is happening in the plant. Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out.During daytime, photosynthesis produces oxygen and glucose faster than respiration consumes it. Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use.

6. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. When taken out of the water, gills (the respiratory organs of fishes) collapse due to which the fishes will not get oxygen further and later on this is the reason for why they die when taken out of the water.
