| Neighbouring plants can suffer, however, the shade cast by the creeper killing other vegetation by limiting their ability to photosynthesise. |
| As CO2 becomes more available, other things being equal, they will photosynthesise more. |
| When the fruit ripen, the plant turns greenish and obtains the ability to photosynthesise. |
| The minuscule zooplankton feed on ocean algae which, like all plants, use carbon dioxide to photosynthesise. |
| The weeds photosynthesise by releasing oxygen into the water during the day and taking it back in at night. |
| 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. |
