Plants are organism who are autotroph, which means that they are able to produce food independently.
The process of making food which plants require to live is called photosynthesis.
Photo means light, and synthesis means to create. Below is the equation:
sunlight
6 CO2 + 12 H20 ——————> C6H12O6 + 6 O2 + 6 H2O
chlorophyll
So without sunlight, plants are unable to synthesize glucose, which is vital to keep them alive.
Answerer 3

photosynthesis is the mechanism by which plants prepare their own food to grow and live.
so they cannot survive without light.
Answerer 4
Is necessary so that the plant can photosynthesize and produce essential biomolecules.
