Are protists eukaryotic or prokaryotic or both?
eukaryotic
Protists are a taxonomically inhomogeneous group of mostly unicellular eukaryotic microorganisms.
Are all protist prokaryotic?
Are protists prokaryotes? Protists consist of both unicellular and multicellular organisms which have a nucleus and membrane-bound organelles. Therefore, protists are eukaryotic, rather than prokaryotic.
Are protists the first prokaryotes?
Introduction. According to the endosymbiotic theory and it’s evidence, scientists propose that the earliest protists evolved from prokaryotes (single-celled organisms) based on available evidence.
Are all organisms prokaryotic or eukaryotic?
Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus….Prokaryotic cell.

Are all protists eukaryotes?
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

Is Protista eukaryote?
Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues. They could be viewed as those eukaryotes that cannot be classified as one of the other cell types. They include the one-celled animal-like protozoa, one-celled algae, slime molds and water molds.
What were the first eukaryotes?
The first eukaryotes were protists. They came into existence with the rise in the oxygen level of the atmosphere.
Which organisms are always eukaryotes?
Eukaryotes may be unicellular or multicellular and include plants, animals, fungi, and protists are all made up of eukaryotic cells.
How are protists and prokaryotes different?
Despite the two being quite similar, they also possess key distinguishing features. For instance, the primary difference is that prokaryotes are strictly unicellular organisms, meanwhile protists are able to assume a variety of both multicellular and unicellular forms.
Are all protists eukaryotic?
Are protists the first eukaryotes?
Summary. Scientists think that protists are the oldest eukaryotes. Protists most likely evolved from prokaryotic cells, as explained by the endosymbiotic theory. This theory is well-supported by evidence.
Are all protists unicellular?
Protists can 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 do not have highly specialized tissues or organs.
Are all unicellular eukaryotes protists?
Protists are eukaryotes as they possess a nucleus and other membrane-bound organelles (structures that perform a specific job). At one time, simple organisms such as amoebas and single-celled algae were classified together in a single taxonomic category: the kingdom Protista.
Are protists prokaryotic or eukaryotic quizlet?
What is the difference between protists and prokaryotes? the major difference is that protists are eukaryotes while bacteria and archea are both prokaryotes. this means that prokaryotes do not have a nucleus, and contain circular DNA.
Is Protista multicellular or unicellular?
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.
Why are protists unicellular?
A Protist is a unicellular, eukaryotic organism. This means that they are made up of one cell and that cell contains a membrane bound nucleus with other specialized organelles. Protists are a part of the kingdom Protista, which includes organisms such as algae and various protozoans.
Why are protists considered eukaryotes?
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
What animals are protists?
Flagella – These types of protists have a tail at the back of their cell body.
Are bacteria and viruses prokaryotics or eukaryotes?
Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
How are protists different from prokaryotes?
Prokaryotes are usually single-celled organisms. They have plasma membrane surrounding the cell but no membrane bound organelles such as the mitochondria, nucleus or Golgi bodies. Protists are all eukaryotes and therefore all have cell organelles, most of them are single-celled but multi-celled form exists.
