What happens to a plant if rate of respiration becomes more than the rate of photosynthesis?

Answer 1

supposedly if plants carried out photosynthesis and respiration at the same rate, then the plant would have no excess sugars (energy)to last them the night... remembering that photosynthesis would only work in daylight hours. Thus, the plant would starve to death basically every night and there would be no life on the earth. All the plant eaters would die making the meat eaters die with them and then there would be no CO2, which is required in photosynthesis... yeah it would be chaotic.

i would do a little more research if i were you to make sure im right :)

Answer 2

The process of photosynthesis itself is the production of "plant food", so without food, a plant will die, as the primary effect. Then every living thing that feed off plants and bacteria would starve. Every predator that feeds off those animals would also die--a massive chain reaction of death. Basically, almost everything would perish. The only living things that would be left are the very few that can do chemosynthesis and do not rely on light to obtain their energy.

Although photosynthesis is the source of free atmospheric oxygen, virtually all multicellular life would have perished long before the oxygen was gradually depleted.

If photosynthesis stopped, the energy from the warm earth would likely give small life (mainly bacteria) the ability to survive. And it is likely that these would evolve mutations through generations that allow them to photosynthesize, just as that ability had evolved several billion years ago.

Recently (2010), a multicellular organism was discovered that lives without oxygen.

Not everything would die, and indeed, evolution (the change in genetic composition over time) would continue even if life didn't require photosynthesis any longer. Since photosynthesis is so efficient, given that the sun shines on the earth, it would likely arise again due to genetic principles.

Answer 3

When the rate of photosynthesis is higher than the rate of respiration, the excess carbohydrates produced are converted into starch and stored in plants, as is the case of potato plant. In case of oilseeds, the excess carbohydrates are converted to lipids and stored in the embryos.

Answer 4

no, because it depends on the weather, like humidity and etc.

Answer 5

There will be shortage of oxygen and the Animal kingdom will suffer.

Answer 6

The plant's fine - until it runs out of stored "food".

Answer 7

It is not only possible, but essential.

Answer 8

You would have turned into a plant.
