What phylum is plankton in?

Answer 1

* I. Kingdom Monera: cells simple and unspecialised; single cells, some in groups or chains. * ** A. Bacteria: single cells in chains or groups; autotrophic and heterotrophic; aerobic and anaerobic; important as a food source and in decomposition. ** B. Cyanobacteria: blue-green algae; autotrophic single cells in chains or groups; produce som red blooms in the sea; phytoplankton. * II. Kingdom Protista: grouping of microscopic and mostly single-celled organisms; autotrophs (algae) and heterotrophs (protozoa). * ** A Phylum Chrysophyta: golden-brown algae; yellow to golden autotrophic single cells in groups or chains; contributing to deep-sea sediments; phytoplankton. ** B Phylum Pyrrophyta: fire algae; single cells with flagella, producing most red tides; bioluminescence common; usually considered phytoplankton. ** *** 1. Class Dinophyceae: dinoflagellates ** C Phylum Sarcodina: radiolarians, foraminiferans, zooplankton. ** D. Phylum Ciliophora: ciliates; zooplankton * III. Kingdom Plantae: plants, primarily nonmotile, multicellular photosynthetic autotrophs. * ** A: Division Phaeophyta: brown algae; ** *** Sargassum: maintains a planktonic habit in the Sargasso Sea. * IV Kingdom Animalia: animals; multicellular heterotrophs with specialised cells, tissues and organ systems; zooplankton (holoplankton= 'whole' always plankton). For temporary members of the zooplankton (meroplankton= larvae of sessile organisms), see Meroplankton below. * ** A Phylum Coelenterata or Cnidaria: radially symmetrical with tentacles and stinging cells. ** *** 1. Class Hydrozoa: jellyfish as one stage in the life cycle, including such colonial forms as the Portuguese man-of-war. *** 2. Class Scyphozoa: jellyfish ** B Phylum Ctenophora: comb jellies, translucent, moving with cilia; often bioluminescent. ** C Phylum Chaetognatha: arrowworms, free-swimming carnivorous worms. ** D Phylum Mollusca: mollusks, the snail-like pteropods. ** E Phylum Arthropoda: animals with paired, jointed appendages and hard outer skeletons ** *** 1. Class Crustacea: copepods and euphausiids. ** F Phylum Chordata: animals including vertebrates with dorsal nerve cord and gill slits at some stage in development. ** *** 1. Subphylum Urochordata: saclike adults with 'tadpole' larvae; salps. * Meroplankton: larval forms from the phyla Annelida (dsegmented worms), Mollusca(shellfish and snails), Echinodermata (starfish and sea urchins) and Chordata (fish).

Answer 2

Plankton can belong to various phyla, including Arthropoda, Chordata, and Cnidaria. They encompass a diverse group of organisms that are found in both freshwater and marine environments.

Answer 3

No. There is not an individual phylum for plankton. Plankton are drifting organism that inhabit the Pelagic Zone, and belong to the kingdoms Animalia, Archaea, Bacteria, and Plantae.
