| Indeed, plankton photosynthesise and even though they only represent less than one percent of the planet's biomass, they absorb almost as much carbon dioxide and produce as much oxygen as all terrestrial vegetation. |
| As CO2 becomes more available, other things being equal, they will photosynthesise more. |
| 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. |
| Carbon is taken out of the atmosphere by trees as they photosynthesise. |
| 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. |
| Neighbouring plants can suffer, however, the shade cast by the creeper killing other vegetation by limiting their ability to photosynthesise. |
