| Some orchids, such as Neottia and Corallorhiza, lack chlorophyll, so are unable to photosynthesise. |
| This means that even during the Arctic winter, some algae can continue to photosynthesise using the very weak light of the polar night. |
| Carbon is taken out of the atmosphere by trees as they photosynthesise. |
| The minuscule zooplankton feed on ocean algae which, like all plants, use carbon dioxide to photosynthesise. |
| Some C4 plants, for example, absorb CO2 and photosynthesise it at either end of special elongated cells, instead of separating the functions out into two different types of cell. |
| The attraction of algae would seem to lie in the possibility that, since they photosynthesise, they could be engineered to contain the whole sunlight-to-fuel process in one genetically engineered package. |
