Nucleus and internal structer
The simplest life form that lacks a nucleus is a prokaryote. Prokaryotes are single-celled organisms that do not have a true nucleus, but instead have a nucleoid region where their genetic material is located. Examples of prokaryotes include bacteria and archaea.
These single celled organisms are called prokaryotes.
An organism with a cell that lacks a true nucleus is a prokaryote. Prokaryotes are single-celled organisms that have genetic material floating freely in the cytoplasm, rather than enclosed within a membrane-bound nucleus. Bacteria and archaea are examples of prokaryotes.
rhodospirillum rubrum are bacteria, meaning that they are prokaryotes. As a rule of thumb, most single-celled organisms are prokaryotes.
Prokaryotes, such as bacteria and archaea, lack a true membrane-bound nucleus. Their genetic material is located in a region called the nucleoid, which is not enclosed by a nuclear membrane.
An organism with a cell that lacks a true nucleus is called a prokaryote. Prokaryotic cells have genetic material that is not enclosed within a membrane-bound nucleus. Examples of prokaryotes include bacteria and archaea.
Bacteria lacks a nucleus but have a fully developed DNA, thus they can be considered full cells. Virus also lack a nucleus, but they have not a fully developed DNA. Even virus having RNA only exist. For this reason virus are somehow in between cells and simple multiple molecular systems.
the terms for prokaryotes are: no nucleus, no membrane organelles, unicelluar, && Eubacteria...
yes prokaryotes have prokaryotes
Bacteria do not have a true nucleus or other membrane-bound organelles inside their cells, which defines them as prokaryotes. The prefix "pro-" in prokaryote means "before" or "lacking," indicating the absence of a true nucleus.
This most significant thing that a prokaryotic cell lacks is a nucleus.
Eukaryotic cells have two types of endoplasmic reticulum: Smooth ER (SER); Rough ER (RER).
