Question

How are protists different from bacteria and archaea?

Answer 1

Hint: Here we have to discuss the protagonist's detail. Then we discuss their difference from the bacteria and archaea. Either of two groups comes within each living organism: eukaryotes or prokaryotes. Cellular composition defines which category corresponds to an organism. Finally we conclude the required answer.

Complete answer:
First we should know about eukaryotes and prokaryotes to answer this question.
Eukaryotes are animals whose cells are surrounded by a plasma membrane, having a nucleus and other organelles.

Organelles are inner structures responsible for a multitude of functions, such as the creation of energy and the synthesis of proteins.
Instead, a little circle of extra genetic material, floating out in the cytoplasm, the fluid that covers the cell, is contained in the nucleoid, an area with no membrane, or even as a plasmid.

Prokaryotic cells, measuring about \[{\text{0}}{{.5 - 1\mu m}}\] in diameter, appear to be thin, basic cells.

Protists are eukaryotes composed of single or several cells, whereas single cell prokaryotes are bacteria and archaea. Bacteria are present everywhere, but only in damp areas can protists be found.
Protists are the most common species that are very hard to identify as some of them have features like trees, animals or fungi.

They are more advanced than bacteria, so they display a greater degree of distinction in the cell structure.
Compared with bacteria, protists are more complicated.

Note: The biggest difference between bacteria and archaea from Protista seems to be in their cellular structures.
Bacteria are believed to be prokaryotes, meaning that they do not possess a nucleus or even other organelles attached to the membrane.
Prokaryotes constitute unicellular species that lack structures attached to the membrane, the nucleus of which is the most notable.
