Kingdom Protoctista includes____________?

C. Protists

The Kingdom Protoctista includes a diverse group of single-celled organisms called protists. Protists are eukaryotic organisms, meaning they have a nucleus and other membrane-bound organelles, but they are not animals, plants, or fungi. The kingdom Protoctista includes a wide range of organisms, including algae, amoebas, and euglena. Protists play important roles in various ecosystems, serving as primary producers in aquatic environments and as decomposers that break down dead organic matter.

A. Fungi are a separate kingdom of eukaryotic organisms that are distinct from protists. Fungi are heterotrophic, meaning they obtain their nutrients by absorbing them from other organisms, and include mushrooms, yeasts, and molds.

B. Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. Prokaryotes include bacteria and archaea.

D. Plantae is the kingdom that includes all plants, from the simplest mosses to the most complex flowering plants. Plantae are multicellular organisms that are capable of producing their own food through photosynthesis.
