Protista

Protists belong to the kingdom of Protista. This kingdom contains unicellular organisms that are eukaryotes. These organisms may form colonies, but they may not form tissues.

Cells

The cell is very diverse.    If an object has no cell it is not alive and anything smaller than a cell is not alive because cells are the most basic units of life.  225 more words

Prokaryotes

What are prokaryotes (“pro-carry-oats”)? They are a type of cell. The other type of cell is a eukaryote (“you-carry-oat”). The difference between the two is that the latter has a nucleus, in which the DNA sits, whereas prokaryotes have no nucleus and their DNA floats around freely. 300 more words

Eukaryotes: A new timetable of evolution

The first single-celled organisms with a nucleus originated more than a billion years later than biogeochemical evidence had previously indicated.

Contaminated samples have evidently created some confusion in the timetable of life. 1,333 more words

The Origins of Eukaryotes: Metagenomic insight into early evolution

The origins of the eukaryotic cell is one of the big puzzles of cell biology. While it has been known for a long time that the eukaryotes are more closely related to the Archaea than to the Bacteria, the ancestor of the eukaryotes has remained elusive. 365 more words

Lokiarchaeota: Missing link for complex cells?

History has given us many puzzles to solve in the field of evolution. According to a recent study, scientists at the Department of Cell and Molecular Biology, Science for Life Laboratory, Uppsala University, Sweden, identified a new class of Archaea, a microorganism that is made up of simple cells like bacteria, called “Lokiarchaeota”, which was noted as a possible missing link between bacteria and their more complex cousins, eukaryotes. 543 more words
