Practice question
Question
Two cells show the following features:
Cell X is relatively small, multiplies rapidly, contains naked genetic material and lacks membrane-bound organelles other than ribosomes.
Cell Y has an organised nucleus, extensive cytoplasmic compartmentalisation and complex cytoskeletal and locomotory structures.
Which conclusion is best supported?
Explanation
Small size, rapid multiplication, naked DNA and absence of membrane-bound organelles identify X as prokaryotic. An organised nucleus and extensive compartmentalisation identify Y as eukaryotic. Eukaryotes include protists, plants, animals and fungi.
