protista

Also known as cells

A protist ( ) or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus. Protists do not form a natural group, or clade, but are a paraphyletic group encompassing the entire eukaryote tree of life, from which land plants, animals, and fungi evolved. They are primarily single-celled, exhibiting a wide range of forms such as amoebae, ciliates, thick-walled microalgae and, more commonly, flagellates. Several transitions to multicellularity have occurred among protists, from colonies with alternating cell types to giant slime molds, fungus-like organisms, and seaweeds w

AI overview

A protist is any single-celled or simple multicellular organism with a nucleus that isn't an animal, plant, or fungus, encompassing a diverse group of amoebae, algae, and other forms of microscopic life. Protists matter because they represent the evolutionary bridge from which animals, plants, and fungi all evolved, and they play important roles in aquatic ecosystems and food chains.

Protista ou Protoctista é um reino de organismos eucariontes (uma célula com núcleo). Inclui todos os eucariontes que não podem ser classificados como parte dos reinos Animalia (animais), Plantae (plantas) ou Fungi (fungos). Possui cerca de 20 mil espécies, sendo um grupo diversificado, heterogêneo, que evoluiu a partir de algas unicelulares. Em alguns casos essa origem torna-se bem clara, como no grupo de flagelados. Há registros fósseis de protozoários com carapaças (foraminíferos), que viveram há mais de 1,5 bilhões de anos, na Era Proterozoica. Grandes extensões do fundo dos mares apresentam espessas camadas de depósitos de carapaças de certas espécies de radiolários e foraminíferos.
