Question

what is the importance of light in photosynthesis

Answer 1

Photosynthesis is the process in plants by which light energy is captured and stored in the plant for it to grow.

Answer 2

Importance Of Light In Photosynthesis

Answer 3

Hope my answer gave you an idea but it is only a rough answer not refined and corrected so please if you are not in a rash look at some biology text and make sure the information I gave you is accurate before you use it.

Photosynthesis is a process by which plants store light enegry in the form of chemical energy. Photosynthesis has two steps.

Light-dependent reaction and Dark reaction

Light Dependent reaction does on as follows:-

Forming a bond is an endothermic process

CO2+H2O=C6H12O6 is a typical example of endothermic process so plants need to supply energy for this process. The question is where do they get this energy.

This get's us back to our quantum lessons. When light energy strikes the leaves they excite electrons and the only fate of these electrons is to fall back to ground state and give off energy. Now our problem is solved, light excites electrons and supplies us with energy.and this energy is trapped by NAD+ and ADP forming NADH and ATP respectively-temporary storers of energy.

In the dark reaction this energy could be used to fix CO2 with hydrogen giving us glucose.

Answer 4

Without light, photosynthesis can't occur. The energy from incoming photons (light) is needed to excite electrons in a plant's chloroplasts to a high energy state: these high energy electrons then drive the rest of the process of photosynthesis.

Answer 5

Extremely important. Without light, no photosynthesis.

Light is made on photons. Reason for the first part of the word.

Synthesis describes a process of conversion.
Plants convert light into energy, that will become a source of food.

Answer 6

Photosynthesis: is the changing of co2 to sugars and oxygen, with out light it can not take place. Light is the key to the whole process.

Answer 7

Generally, it is currently believed that light shining on photoreceptors causes electrons to become "excited" to a higher energy level which sets off a chain of transportation of electrons which are used as catalysts in chemical reactions that produce sugars in the presence of CO2.

The photons drive the electron transport chain which produces ATP and NADPH. These are used in the calvin-benson cycle to fix CO2. D is the answer.

Answer 9

To supply energy.
