| The weeds photosynthesise by releasing oxygen into the water during the day and taking it back in at night. |
|
| The minuscule zooplankton feed on ocean algae which, like all plants, use carbon dioxide 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. |
|
| 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 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. |
|
| 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. |
|
| In carnivorous plants, the leaf is not just used to photosynthesise, but also as a trap. |
|
| Neighbouring plants can suffer, however, the shade cast by the creeper killing other vegetation by limiting their ability to photosynthesise. |
|
| Carbon is taken out of the atmosphere by trees as they photosynthesise. |
|
| Some orchids, such as Neottia and Corallorhiza, lack chlorophyll, so are unable 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. |
|
| Each bit of debris was, in effect, a tiny ecosystem. As with many ecosystems, the bottom of the food chain was occupied by things that photosynthesise. |
|
| There's insufficient light for them to photosynthesise so they may be dormant. |
|
| For a plant to grow, it must photosynthesise more than it respires. |
|
| The roots are often green and help the plant photosynthesise. |
|
| I think that it's got something to do with the fact that eating so much plant material makes you half plant, and you need the sun to photosynthesise. |
|
| Ideally, you won't mow the lawn again until around May so the leaves of the crocus have had time to photosynthesise and gather enough energy for next year's display. |
|
| Mr Booty said if the flag-leaf does not have the chlorophyll, it cannot photosynthesise sunlight to produce the carbohydrates needed for grain fill. |
|
| They add that the MR253 variety may have a lower susceptibility to intense lights, considering that it needs less nitrogen than other rice varieties to photosynthesise. |
