What is kingdom protista?

Question

what is it composed of?

Answer 1

Members of the Kingdom Protista are the simplest of the eukaryotes. Protists are an unusual group of organisms that were put together because they don't really seem to belong to any other group. Some protists perform photosynthesis like plants while others move around and act like animals, but protists are neither plants nor animals. They're not fungi either - even though some might like to "think" they are!

In some ways, the Kingdom Protista is home for the "leftover" organisms that couldn't be classified elsewhere. You might not think a tiny one-celled amoeba has much in common with a giant sea kelp, but they're both members of this kingdom.

Protists (IPA: /ˈproʊtɨst/), are a diverse group of eukaryotic microorganisms. Historically, protists were treated as the kingdom Protista but this group is no longer recognized in modern taxonomy. The protists do not have much in common besides a relatively simple organization -- either they are unicellular, or they are multicellular without specialized tissues. This simple cellular organization distinguishes the protists from other eukaryotes, such as fungi, animals and plants.

The term protista was first used by Ernst Haeckel in 1866. Protists were traditionally subdivided into several groups based on similarities to the "higher" kingdoms: the one-celled animal-like protozoa, the plant-like protophyta (mostly one-celled algae), and the fungus-like slime molds and water molds. Because these groups often overlap, they have been replaced by phylogenetic-based classifications. However, they are still useful as informal names for describing the morphology and ecology of protists.

Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton. Other protists, such as the Kinetoplastids and Apicomplexa are responsible for a range of serious human diseases, such as malaria and sleeping sickness.

Answer 2

basically single celled organisms such as a protozoa.
