Solution:

Carbon dioxide is still present when a plant is kept in the dark and properly ventilated. A sufficient amount of water can be provided to the plant to ensure its life. The seed, however, would eventually die due to deficiency of nourishment. on top of that, a green plant will not be able to carry out the process of photosynthesis. So, even if the plant gets proper ventilation and is provided with nutritional supplements, it will be of no use and the plant will eventually die.
