Volvox How does your organism get nutrients
The ability for eukaryotes to carry out photosynthesis was made possible by one or more symbiotic associations between heterotrophic eukaryotes and photosynthetic prokaryotes (or their descendents). There were several primary symbioses between eukaryotes and blue green algae. In one lineage, the photosynthetic organism lost much of its genetic independence and became functionally and genetically integrated as chloroplasts within the host cell. Modern chloroplasts, also called plastids, are bounded by two or more membranes, and most usually lie free in the cytoplasm, but in some cases they may be located within a fold of the nuclear envelope, or may be associated with the cytoplasm and residual nucleus of a eukaryotic endosybiont. The descendents of some of these primary plastids have gone on to form further associations. At least two types of protists (chloroarachniophytes and cryptomonads) have acquired 'plastids' by forming symbioses with eukaryotic algae. This are referred to as secondary symbioses.

In general, plants require nitrogen in the form of soil nitrates which their roots can absorb.
Cyanobacteria are the only organisms able to perform both oxygenic (oxygen-generating) photosynthesis and

There are several interesting facts about the members of green algae, out of which a few are enlisted below:
There are about 7000 species of green algae, which can be found in both fresh or saltwater and also in damp places.
They are considered as the group from which the higher plants evolved on the basis of certain characteristics, and the compounds found in the pigments used for photosynthesis.
Out of all green algae, the members of the order are considered as the closest relatives of higher plants.
Almost all of them contain chloroplast, within which the pigments chlorophyll 'a' and 'b' can be found.
