kingdom protista 3 groups

There are 3 groups that we can use to organize Kingdom Protista: (these are not taxa but informal names) Animal-like (Protozoa) Plant-like (Algae, or Protophyta) Fungus-like (Slime Molds and Water Molds) protists; Each group is composed of multiple phyla based on their nutrition and motility. 1. subkingdom protozoa -heterotrophic 2. subkingdom algae -completely autotrophic NOT phyla. However, the boundaries of this kingdom are not well defined. Members of Protista are primarily aquatic. Among the brown algal protists, some forms may reach a length of 60 metres or more, although the normal range is 5 micrometres to 2 or 3 millimetres. The kingdom Protista (in the five kingdom system) contains mostly unicellular eukaryotes. Protists are both heterotrophs or autotrophs. No one even knows how many species there are, though estimates range between 65,000 to 200,000. Example: Algae- Spirogyra, Euglena, etc. The pant protists are autotrophs. 1.phylum Mastigophora 2. phylum Sarcodina 3. phylum Ciliophora 4. Animal and fungus-like protists are heterotrophs. Algae are a group of protists that comes closer to plants because they can perform photosynthesis. Example- … Protists are organisms in the kingdom Protista. Kingdom Protista. The protist then transports its cytoplasm into the pseudopod, thereby moving the entire cell. These organisms are eukaryotes, meaning they are made up of single or multiple cells which all contain a nucleus enclosed by a membrane. The Kingdom Protista includes an incredible diversity of different types of organisms, including algae, protozoans, and slime molds. 2 main groups in Kingdom Protista. This kingdom forms a link with the others dealing with plants, animals and fungi. Some parasitic forms and a few free-living algal protists may have a length of 1 … Phylum Sporozoa distinguished by methods of locomotion. All protists are not microscopic. The old Kingdom Protista, as I learned it long ago, thus contains some living groups that might serve as possible models for the early eukaryotes. Some groups have large species indeed; for example, among the brown algal protists some forms may reach a length of 60 metres (197 feet) or more. The biological kingdom Protista includes a group of unique life forms composed of eukaryotic cells which can be unicellular as well as multicellular. Characteristics of Kingdom Protista. There are 3 main groups of protista, each has its own characteristics and function. Protistan Groups. Eukaryotic and single-celled, also called unicellular organisms to come under this group. This taxonomic grouping is polyphyletic and based only on cellular structure and life styles not on any molecular evidence. The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or … Kingdom Protista Phyla Groups . Protists are classified into three major groups based on their type of nutrition. Introduction to Kingdom Protista . 4 phyla within subkingdom protozoa. Not all protists are microscopic. These are algae, slime molds, and protozoa. This taxonomic kingdom has been broken into many new kingdoms, reflecting new studies and techniques that help … This type of motion, called cytoplasmic streaming, is used by several diverse groups of protists as a means of locomotion or as a method to distribute nutrients and oxygen. Protozoa, or animal-like protists, are heterotrophs that ingest or absorb their food. We place all single-celled eukaryotes under Protista. Algae – Protists that perform photosynthesis.
