Most algae are unicellular.

Sporangiospores (4-11 m diam) are produced in the sporangium and are unicellular, ovoid and brown.
An early impression of previously determined flows suggests that in an essentially unicellular oscillatory flow, the thermals originate symmetrically from the centre of the upper and lower boundaries.
Although the variances were high, there was some indication that unicellular bacteria numbers were not closely correlated with soil type but that filamentous bacteria and fungi could have been.
While the river does not support complex metazoan life (although rotifers and insect larvae have been observed), unicellular eukaryotes are abundant and more diverse than prokaryotes.
Molecular trees show that the transition of unicellular eukaryotes to multicellularity occurred multiple times in distinct lineages.
A multicellular organism must, and a unicellular organism may, sometimes grow.
It is suggested that their original role in evolution probably was to promote cell growth and division of unicellular organisms by turning over cell-wall -1,3glucans.
All zones are produced by filamentous fungi (mycobionts) and unicellular green algae (phycobionts), which together form a symbiotic lichen association.
