Exempel på unicellular

• In particular, a unicellular organism corrects direction of its own motion reacting to changes in the environment.

• Sponges have no nervous systems at all and hence no individuality in the sense that ordinary unicellular and multicellular organisms are individuals.

• Bacteria are frequently said to be typical unicellular organisms.

• Three papers review important areas in unicellular complexity.

• On the basis of their dimensions and morphological considerations, the sphaeromorph acritarchs are interpreted as probably representing the resistant, reproductive cysts of unicellular protists.

• Unicellular organisms may respond by using complex taxis.

• Permanent gross leakage, which may result from imbibitional stress, inevitably leads to cell death in unicellular organisms.

• All zones are produced by filamentous fungi (mycobionts) and unicellular green algae (phycobionts), which together form a symbiotic lichen association.

• 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.

• A multicellular organism must, and a unicellular organism may, sometimes grow.

• Molecular trees show that the transition of unicellular eukaryotes to multicellularity occurred multiple times in distinct lineages.

• 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.

• 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.

• 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.

• Sporangiospores (4-11 m diam) are produced in the sporangium and are unicellular, ovoid and brown.
