Prokaryote or eukaryote?
This organism consists of a single jail cell with several flagella. Is information technology a prokaryote, such equally a bacterium? Actually, it's larger than a prokaryotic cell, and it also has a nucleus. Therefore, this organism belongs to the domain Eukarya, the domain that includes humans. This particular eukaryote is 1 of the smallest, simplest organisms in the domain, chosen a protist. It's scientific name is Giardia lamblia. As a human parasite, information technology tin can make us sick.

Kingdom Protista
Protists are a group of all the eukaryotes that are not fungi, animals, or plants. Equally a result, information technology is a very various group of organisms. The eukaryotes that make upward this kingdom, Kingdom Protista, practise not have much in mutual besides a relatively simple organization. Protists tin look very different from each other. Some are tiny and unicellular, like an amoeba, and some are large and multicellular, like seaweed. However, multicellular protists practice not have highly specialized tissues or organs. This simple cellular-level organization distinguishes protists from other eukaryotes, such as fungi, animals, and plants. At that place are idea to exist between 60,000 and 200,000 protist species, and many have yet to exist identified. 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. Other protists are responsible for a range of serious homo diseases, such as malaria and sleeping sickness.
The term protista was first used by Ernst Haeckel in 1866. Protists were traditionally placed into one of several groups based on similarities to a plant, beast, or fungus: the fauna-likeprotozoa, the plant-similar protophyta (mostly algae), and the fungus-like slime molds and h2o molds. These traditional subdivisions, which were largely based on not-scientific characteristics, have been replaced by classifications based on phylogenetics (evolutionary relatedness amidst organisms). However, the older terms are still used every bit informal names to describe the full general characteristics of various protists.
Protists range from unmarried-celled amoebas to multicellular seaweed. Protists may be similar to animals, plants, or fungi.
Summary
- Kingdom Protista includes all eukaryotes that are not animals, plants, or fungi.
- Kingdom Protista is very diverse. It consists of both single-celled and multicellular organisms.
Review
- What are protists?
- How are unicellular protists and multicellular protists like?
- How are protists classified? What are the master categories of protists?
