Protist

Protists (IPA: /ˈproʊtɨst/), Greek protiston -a meaning the (most) first of all ones, are a diverse group of organisms, comprising those eukaryotes that cannot be classified in any of the other kingdoms as fungi, animals, or plants.

Protist A member of the protista kingdom. Includes but is not limited to: slime molds, water molds, all protozoans (ciliates(parameciums), zoomastigina, rhizopoda(amoebas), etc.) and plant like protists (clorophyta, golden algae, euglena, etc. ) ...

Protists are a heterogenous group of living things, comprising those eukaryotes which are neither animals, plants, or fungi. They are usually treated as a kingdom Protista or Protoctista, first introduced by Haeckel.

Protists without typical mitochondria Choanoflagellates The Protists What are protists?

Protista Eukaryotes are organisms with complex cells, in which the genetic material is organized into membrane-bound nuclei.

Protists exhibit a great deal of variation in their life histories (life cycles). They exhibit an alternation between diploid and haploid phases that is similar to the alternation of generations found in plants.

protist A member of the kingdom Protista, generally considered to include the protozoa and eukaryotic algae. Protista The kingdom whose members are characterized by being eukaryotic and unicellular or colonial. proto-oncogene. See oncogene.

A protist that lives primarily by ingesting food, an animal-like mode of nutrition. provirus Viral DNA that inserts into a host genome.

Some protists have specialized contractile vacuoles for eliminating excess water and food vacuoles that contain food within the cell. Chloroplasts The diagram below illustrates how energy from sunlight is used for the energy requirements of cells.

The kingdom Protista as it now stands includes the unicellular and a few simple multicellular eukaryotic organisms with no well defined tissues or organs.

Radiolaria. Protistan phylum, whose members are planktonic and secrete an often elaborate siliceous test Radula. A belt of teeth, found in gastropods and chitons. Used for feeding.

An organism whose cells possess a nucleus and other membrane-bound vesicles, including all members of the protist, fungi, plant and animal kingdoms; and excluding viruses, bacteria, and blue-green algae. See Prokaryote. Evolution.

Apicomplexa Division of Protista which includes many parasites such as Plasmodium vivax which causes malaria (api = bee or apic = apex‚ summit‚ tip)    Araceae a family of monocots whose flowers are in the form of a spathe and spadix ...

Mitochondrial genomes are small and gene-rich with a conserved complement of genes that are homologous among plants, protists, fungi, and animals.

In 1969 Whittaker proposed a "five kingdom" system in which three kingdoms were added to the animals and plants: Monera (bacteria), Protista, and Fungi. Whittaker defined the kingdoms by a number of special characteristics.

Eukaryotes include protists (single celled organisms like amoebas and diatoms and a few multicellular forms such as kelp), fungi (including mushrooms and yeast), plants and animals.

Hair-like structure attached to a cell, used for locomotion in many protists and prokaryotes.

Many organisms - plants, fungi, protists, bacteria, etc. - accumulate metals when grown in a solution of them, either as part of their defence mechanism against the poisonous effect of those compounds, ...

- the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP. Pigeonpea ...

Ciliates: This group of protists is most like animals in their behaviour and complexity. The Paramecium is the representative of the Ciliates.

contractile vacuole An organelle that pumps excess water out of many freshwater protist cells. cork cambium A cylinder of meristematic tissue in plants that produces cork cells to replace the epidermis during secondary growth.

Protist cell - kingdom containing organisms with eukaryotic cells that are unicellular and multicellular and reproduce sexually and asexually ...
