What does the sun have to do with photosynthesis?

Answer 1

In photosynthesis, the plant takes in water through the roots and carbon dioxide through the leaves. in order to convert carbon dioxide and water into glucose, the plant needs energy from the sun, or sunlight. the Chlorophyll captures the light energy for the plant.

Answer 2

Photosynthesis is the process by which plants and other autotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts. So, plants take in carbon dioxide and release oxygen, and the other way around for humans. So, don't "kill" plants (well, some would say especially trees)! (en.wiktionary.org/wiki/photosynthesis for definition)
well they are not needed by pants they are needed by plants because it is their food processing.

Answer 3

Photosynthesis is often the basis of the food chain. It is a plant's method of making food/energy for itself, which means the plants rely only on sun and CO2 for their energy source, which make them an ideal candidate for the start of a system of other organisms getting their energy resource from another organism, ie a plant.

Answer 4

Of course it does.

You can look at the photosynthesis equation at first:

6CO2 + 6H2O -> C6H12O6 + 6O2

The water is first split into H2 and O, the O is first released as a waste product in the photosystem II (using light spectrum 680). Then the hydrogen is used as a electron carrer, carried to the primary acceptor, go through the ETC producing some ATP since doing this process does require some energy like any other cellular process does. Anyway, then the Hydrogen electron is brought down to the Photosystem I, using light P700 then carry that electron to the primary acceptor, then that is carried by FADH (simply a carrier) then brought to the NADP, which is reduced down to NADPH, which is used to carry hydrogen to the Calvin Cycle to make sugar in the light-independent reaction.

So the water splits into Oxygen as a waste product and use Hydrogen to make sugar, glucose, you can tell it from the equation that we're making a molecule with Carbon, hydrogen and oxygen with carbon dioxide and something that has hydrogen in it.

Therefore, yes, Photosynthesis is very dependent on water.

Answer 5

Water is essential for photosynthesis.

In the presence of light:

Carbon dioxide + water ---> sugar + oxygen

Answer 6

Photosynthesis is the process plants use to create energy which they use from carbon dioxide and the sun.

Answer 7

Chloroplasts are sites of photosynthesis.It takes place in chloroplast.

Answer 8

it gives it food
