2. What are the classifications of organisms?

The general classification level of organisms: Kingdom, Phylum, Class, Order, Family, Genus, Species. The specific classification level of organisms: Superkingdom, Kingdom, Phylum, Subphylum, Superclass, Class, Subclass, Superorder, Order, Subborder, Superfamily (-oidae), Family (-idae), Subfamily (-inae), Genus, Subgenus, Species, Subspecies. Organisms are composed of prokaryotes and eukaryotes, that is, animals, plants, and microorganisms, and their characteristic is that they can carry out metabolism. Plants include algae, mosses, ferns, seed plants (herbs belong to seed plants), and microorganisms; Animals include mammals, amphibians, marine animals, and microorganisms; Microorganisms include fungi, bacteria, mycoplasma, chlamydia, rickettsia, spirochetes, actinomycetes, and viruses. The basic substances and main structures of living things (except viruses) The basic substances in biological cells are: water, nutrients, mitochondria, nucleic acids, and plants also have chlorophyll. The main structures of biological cells are: cell membrane, cell nucleus, cytoplasm, and plants also have cell walls, chloroplasts, and vacuoles (blastocysts).

Jellyfish belongs to the phylum Cnidaria, class Scyphozoa, order Rhizostomidae, family Rhizostomidae, genus Acarina.

Shellfish belong to the phylum Mollusca, and different shellfish belong to three different classes in the phylum Mollusca - Gastropoda, Bivalvia, and Cephalopoda. Gastropoda usually have a spiral shell, but the shell's shape varies a lot. Bivalvia, also known as Bivalvia or Axepoda, is the class with the most species and the greatest economic value among all classes in the phylum Mollusca. It is characterized by having a shell on each side of the body (some species such as abalone have one shell)

Grade 5, Grade 8 Biology (Classification of Plants)

Plants do not have these major distinctions, only animals do.
