What phylum is plankton in?

Answer 1

Plankton is not classified under a single phylum, as it is a diverse group of organisms that can belong to various phyla. Plankton includes organisms such as diatoms (phylum Bacillariophyta), dinoflagellates (phylum Dinoflagellata), and copepods (phylum Arthropoda). These organisms can be further categorized into phytoplankton (plant-like) and zooplankton (animal-like) based on their primary source of nutrition.

Answer 2

* 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 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.

Answer 4

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.
