Vedclass · Answer

(B) Green plants cannot perform photosynthesis in complete darkness because light energy is essential for the light-dependent reactions of photosynthesis.Photosynthesis requires light to convert $CO_2$ and $H_2O$ into glucose and oxygen.To maintain its survival in the dark,the plant can be provided with organic nutrients (like glucose or sucrose) through the soil or by external application,as it cannot synthesize its own food.However,it will eventually die if kept in the dark for a prolonged period due to the lack of light-dependent metabolic processes.

If a green plant is kept in the dark with proper ventilation,can this plant carry out photosynthesis? Can anything be given as a supplement to maintain its growth or survival?
