Photosynthesis is a process that helps green plants synthesize their food. A cascade of events and chemical reactions take place in a specified sequential order. Choose an event that does not take place in photosynthesis.
Options
AAbsorption of light energy by chlorophyll
BReduction of carbon dioxide to carbohydrate
COxidation of carbon to carbon dioxide
DSplitting of water

Correct Answer
COxidation of carbon to carbon dioxide
Model Answer
About Photosynthesis
Photosynthesis is the process used by green plants and a few organisms that use sunlight, carbon dioxide and water to prepare their food.
Chloroplasts are specialized organelles in which photosynthesis takes place. Because it has its own DNA and genes, this organelle can make its own proteins.
The stroma, the fluid, and the stack of thylakoids known as grana make up chloroplasts.
Chlorophyll a, chlorophyll b, and carotenoids are three important pigments in the chloroplast that absorb light energy.
The process of Photosynthesis is composed of following step
Absorption of light energy by chlorophyll.
Conversion of light energy into chemical energy
Splitting of water molecules into hydrogen and oxygen.
Reduction of carbon dioxide to form carbohydrate. Hence correct answer is Option C.
These steps need not take place one after another immediately. For example; desert plants take up carbon dioxide at night to make an intermediate. During daytime. they make carbohydrate. After photosynthesis, carbohydrate is converted into starch and starch is stored in different plant organs.
