Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
What are eukaryotes simple definition?
- The Protists. Protists are one-celled eukaryotes.
- The Fungi. Fungi can have one cell or many cells.
- The Plants. All of the roughly 250,000 species of plants -- from simple mosses to complex flowering plants -- belong to the eukaryotes.
- The Animals.
What organisms are eukaryotic?
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. They are classified under the kingdom Eukaryota. They can maintain different environments in a single cell that allows them to carry out various metabolic reactions.

Which are eukaryotic cells?
Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
What does eukaryotic mean in Greek?
Eukaryotes (/juːˈkærioʊts, -əts/) are organisms whose cells have a nucleus enclosed within a nuclear envelope. They belong to the group of organisms Eukaryota or Eukarya; their name comes from the Greek εὖ (eu, "well" or "good") and κάρυον (karyon, "nut" or "kernel").
What does prokaryotic and eukaryotic?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
What is meant by prokaryotic?
prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes.

Which statement listed below is true about endosymbiosis?
The statements that are TRUE regarding the endosymbiosis theory are the endosymbiosis theory tells us how the eukaryotic cell first arose and that strong evidence in support of the theory is that the DNA of chloroplasts and mitochondria is very closely related to DNA sequences from 2 different groups of bacteria.
Which life cycle relies on a sole multicellular diploid stage that produces haploid gametes?
There are three main categories of sexual life cycles. In a diploid-dominant life cycle, the multicellular diploid stage is the most obvious life stage, and the only haploid cells are the gametes. Humans and most animals have this type of life cycle.
Where does the word "prokaryote" come from?
Prokaryote comes from the Greek word for prenucleus (meaning primitive nuclear material containing cell).
