CAIE A Level Biology 9700 · Classification, biodiversity and conservation
A new unicellular organism, Novella marina, has been discovered in coastal waters. It has a nucleus, chloroplasts, a cell wall made of cellulose, and reproduces by binary fission.
Describe how biologists would determine the species identity of Novella marina and classify it using the taxonomic hierarchy from domain to species. In your description, refer to the species concepts and the characteristic features of the kingdom to which it belongs.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Describe means: Say what happens or what something is like, in order and with detail. You are not being asked why. If there is data, quote it: name the trend, then give figures with units at the points where it changes.
