Question

How many eukaryotic domains are there?

Answer 1

Hint: Organisms whose cells have a nucleus enclosed in a nuclear envelope are known as eukaryotes. The eukaryotic domain constitutes one of the three domains of life; prokaryotes-bacteria and archaea form the other two domains. Eukaryotes account for only a small part of living organisms; however, because they are usually much larger in size, it is estimated that their total global biomass is roughly equal to that of prokaryotes.

Complete answer:
The cells of eukaryotes are more complicated than the prokaryotic cells. They are large and have membrane-bound organelles such as nuclei, mitochondria, and chloroplasts. Eukaryotes can be single-celled or multicellular, and include multiple cells that form different types of tissues; in contrast, prokaryotes are usually single-celled. Most familiar eukaryotes are animals, plants, and fungi; other eukaryotes are sometimes called protists.
The eukaryotes represent a domain of life but there are multiple different kingdoms within this domain. The most common classification creates four kingdoms in this domain, which are: Protista, Fungi, Plantae, and Animalia. These domains are further divided into many smaller categories: phylum, class, order, family, genus, and species.
The most influential system is the “Whittaker” five-world structure, which recognizes Monera (prokaryotic) and four eukaryotic kingdoms: Animalia, Plantae, Fungi and Protista. Whittaker’s system is slightly modified and is presented as more realistic than the traditional division of life into animals and plants.

So, the answer to this question is Four.

Note:
The origin of eukaryotic cells is a milestone in the evolution of life, because eukaryotes include all complex cells and almost all multicellular organisms. Various methods have been used to find the first eukaryotes and their closest relatives. The Last Eukaryotic Common Ancestor (LECA) is the last hypothetical common ancestor of all eukaryotes, and it is likely to be a biological population.
