Each of these organelles performs a specialized function in the cell. Organisms that are not eukaryotes are called prokaryotes. Prokaryotes are exclusively unicellular organisms and are characterized by a lack of membrane-bound organelles, such as the nucleus, that are found in eukaryotes. Kingdom ...
There are three domains of living things: Archaea, Bacteria, and Eukarya. The domain Eukarya includes all organisms that have nuclei in their cells. Within Eukarya, there are four kingdoms: Protista, Fungi, Plantae, and Animalia. All organisms in each kingdom have certain traits in common. So...
orarchaeonon Earth. These organisms may be classified in various ways. One of the ways is by basing upon the number ofcellsthat make it up. The two major groups are thesingle-celled(e.g.bacteria,archaea, andprotists) and themulticellular(animals and plants). Organisms can also be classifie...
Also referred to as Sac Fungi, phylum Ascomycota is the largest phylum (makes up about 75 percent) of the Kingdom Fungi with well over 60,000 species of organisms. Organisms that are grouped under this phylum are collectively known as ascomycetes including yeast (single celled organisms) and...
Before the introduction of the current highest rank called domain in 1990 by Carl Woese, Otto Kandler, and Mark Wheelis, kingdom occupied the highest rank in all the taxonomic classification systems; applying ubiquitously for all types of organisms like plants, animals, fungi, bacteria, archaea,...

A zygote is the first diploid eukaryotic cell that resulted from the fusion of haploid gametes (sperm and an ovum) during sexual reproduction.It is the initial stage of an embryo from which a multicellular organism develops. It is also seen in unicellular organisms, where instead of becoming em...
Eukaryotic cells are cells which contains a nucleus enclosed within the nuclear membrane. Protozoa, fungi, plants, and animals are the few eukaryotic organisms.
In this lesson, see the definition of a phylum and how phylum classification is organized. Understand some reasons why organisms are put into...
Ananimal(plural: animals) refers to any of the eukaryotic multicellularorganismsof the biological kingdom Animalia. Animals of this kingdom are generally characterized to be heterotrophic, motile, having specialized sensory organs, lacking acell wall, and growing from ablastuladuring embryonic development...
