Answer 7

Yes.

Plankton range in size from tiny microbes (1 micrometre [0.000039 inch] or less) to jellyfish whose gelatinous bell can reach up to 2 metres in width and whose tentacles can extend over 15 metres.

i would say no. plankton have yoru typical makeup, i.e. brain, skin, bones/exoskeleton. that sort of thing. jellyfish are invertebrates and lack a backbone which would place them in a different sub category I'd think.
