Answer:
Not much difference it will make to the plant.
I assume here that the polythene is transparent, so that sufficient sunlight will reach the plant for optimal level of photosynthesis.
Under such condition, the rate of photosynthesis will be more than the rate of respiration. Therefore, at the end of the study period the concentration of CO2 will go down and concentration of oxygen will go up in the enclosed air. There will be net organic carbon accumulation in the plant body. And the temperature of the enclosed air will go up.
