Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

According to scientists, the world is split into two kinds of organisms — prokaryotic vs. eukaryotic — which have two ...

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important ...

This is exactly what scientists suspect happened to form a whole new type of cell, the eukaryote, which thrived and subsequently diversified into the macroscopic array of life we see today, including ...

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary biologist Jeffrey Palmer of Indiana University, Bloomington, ...

Eukaryotic microorganisms, or protists, are essential ecological agents that populate various environments like aquatic and ...

Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings ...
