Most plants cannot live without CO2 because it is required for photosynthesis. The rare exceptions would be parasitic plants, such as Indian pipe and Rafflesia, that lack chlorophyll and cannot conduct photosynthesis. However, such parasitic plants obtain their energy from photosynthetic plants, which do require CO2. It is also possible to grow mutant plants that lack chlorophyll, such as albino corn, by feeding them a sugar solution. Albino plants do not require carbon dioxide when supplied sugar.
