Can photosynthesis occur under water

Answer 1

Yes! Because water is used to make glucose (by photosynthesis) a shortage of water could and would directly affect the process of photosynthesis. When there is no water, the guard cells close the stomata in order to conserve water, this action shuts of the plants supply of carbon dioxide, slowing the rate of photosynthesis, and if not given water the plant will run out of simple sugars and starch and die.

Answer 2

No it cannot. The formula for photosynthesis requires water in order for oxygen to be created.

The formula is:

6 CO2 + 6 H2O →C6H12O6 + 6 O2

That's 6 carbon dioxide+ 6 oxygen creates sugar and 6 free Oxygen. Without water the formula could not succeed.

Answer 3

Yes, although only when the water is clear and shallow enough for sunlight to travel through the water to plants like algae helping them survive. However, some algea species are able to live further down and photosynthesize. Rhodophyta, red algea, is able to photosynthesize because of a pigment called phycoerythrin which allows them to absorb more blue light wavelengths. The fact that it can absorb blue light is important these shorter wavelengths are able to penetrate into the water further.

Answer 4

Photosynthesis can occur in shallow and clear water that sunlight can get through. It can also occur on the surface of water.

Answer 5

Photosynthesis does not require Oxygen. Oxygen is produced by photosynthesis.

Photosynthesis need Carbon dioxide. It cannot occur without CO2
