Question

what is photosynthesis???​

Answer 1

$\huge \bold \blue{answer}$

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

$\sf{\underline{\overline{\pink{Photosynthesis :}}}}$

• $\bold{Photosynthesis}$ is the process by which living plant cells which contains chlorophyll, produce food substances like glucose and starch from carbon dioxide and water by using light energy.

• It provides food for all living beings including animals and humans.

• It provides us oxygen to breathe in by releasing oxygen into the atmosphere.

$\bold{Photosynthesis\: can\: occur \:in\: two\: phases :}$

1. Light Reaction :

• $\bold{Light\: reaction}$ traps the energy by using chlorophyll and use that energy in splitting water molecules into hydrogen and oxygen which is called photolysis.

2. Dark Reaction :

• $\bold{Dark\: reaction}$ transfer the hydrogen from NADPH through a series of chemical reactions to combine with carbon dioxide to produce glucose by using energy from ATP.

$\sf{\underline{\overline{\purple{Types \: of \: photosynthesis :}}}}$

$\bold{There\: are\: two\: types\: of\: photosynthetic\: processes:}$

1. Oxygenic photosynthesis :

• $\bold{Oxygenic\: photosynthesis}$ is a non-cyclic photosynthetic electron chain where the initial electron donor is water and, as a consequence, molecular oxygen is liberated as a byproduct.

2. Anoxygenic photosynthesis :

• $\bold{Anoxygenic\: photosynthesis}$ is the phototrophic process where light energy is captured and converted to ATP, without the production of oxygen; water is, therefore, not used as an electron donor.
