They are mainly unicellular but some are multicellular such as seaweed for example. Protists are a group of all the eukaryotes that are not fungi, animals, or plants. Kingdom Protista 2. 1. an organism whose cell(s) contains a nucleus and organelles. However, the boundaries of this kingdom are not well defined. Their mode of nutrition is highly diverse as well, ranging from photoautotrophs to heterotrophs to mixotrophs (a combination of the first two). Some species exhibit both autotrophic and heterotrophic nutrition. PLAY. Autotrophic or heterotrophic mode of nutrition. Kingdom protista 1. This kingdom belongs to the domain Eykarya. The main difference between Monera and Protista is that unicellular prokaryotes are classified into kingdom Monera whereas unicellular and multicellular eukaryotes, which are not either fungi, plants or animals, are classified into kingdom Protista. Protist Characteristics: Protists are so small that they do not need any special organs to exchange gases or excrete wastes. We place all single-celled eukaryotes under Protista. Few species are saprophytes i.e., they feed on dead and decaying organic matters. They break down plant fibres such as dead leaves and wood and allow the nutrients to release into the soil. KINGDOM PROTISTA. The term Protista was first used by Ernst Haeckel in the year 1886.

Kingdom Protista contains the protists, or all the organisms that do not fit into the other kingdoms of life. For classification, the protists are divided into three groups: animal-like protists, plant-like protists, and fungi-like protists. Nutrition- include both heterotrophic and autotrophic. A protist is a group of eukaryotic organisms which are not classified as either an animal, plant or fungus. The Endosymbiosis Hypothesis suggests that the first protist cell was formed by a symbiosis among several prokaryotes (bacteria). II. Respiration in these organisms vary, few are obligate aerobes, while some are obligate anaerobes and facultative anaerobes. Kelp, or 'seaweed,' is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems. These cookies do not store any personal information.
