Question

Photosynthesis is a
a oxidation process
b reduction process
c both a and b
d. none​

Answer 1

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. 

Answer 2

Answer:

Photosynthesis involves the reduction of carbon dioxide into sugars and the oxidation of water into molecular oxygen. The reverse reaction, respiration, oxidizes sugars to produce carbon dioxide and water.

Oxidation: 4 H2O(l) + Mn2+(aq) → MnO−; 4(aq) + 8 H+(aq) + 5 e−

Reduction: 2 e− + 6 H+ + BiO−; 3(s) → Bi3+(aq) + 3 H2O(l)

THEREFORE BOTH A AND B
