FULL ANSWEROcean plants are prepared for the influx of salt, as their cell membrane permits the salt in, gathering it in the vacuole of the cell. Then salt concentration can go up even higher than that of the surrounding water, and the cells do not go through plasmolysis. There is just one gene that makes the difference between causing plasmolysis and accepting the salt, and scientists have experimented with fresh water plants by adding that gene to their makeup. After that adjustment, the new plants were tolerant of salt water.In freshwater plants, though, the membrane holds the salt out, while the water comes into the cell. Unfortunately, this is harmful for the cell wall, which is what causes the plant to start to die. There is no way to reverse plasmolysis once it begins, so knowing which water to use is crucial for the health of plants.Hope it helps

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
