Domain Bacteria Cell Type
These lucas eventually evolved into three different cell types each representing a domain.
Domain bacteria cell type. One proposes that the diploid or 2n nature of the eukaryotic genome occurred after the fusion of two haploid or 1n prokaryotic cells. The prokaryotic organisms that were formerly known as bacteria were then divided into two of these domains bacteria and archaea. Archaea bacteria and eukarya.
For example they do not have intracellular organelles and they have circular dna. These lucas eventually evolved into three different cell types each representing a domain. Photoautotrophic species have chloro phyll but not chloro plasts which are organelles that are separated form the surrounding cytoplasm by their own membranes.
However they are fundamentally distinct and their separation is based on the genetic evidence for their ancient and separate evolutionary lineages as well as fundamental differences in their chemistry and physiology. Cocci are spherical prokaryotic cells that are usually found in clusters or colonies. Lack organelles such as centrioles eukaryotic flagella cilia mitochondria and chloroplasts.
Bacteria and archaea are superficially similar. The three domains are the archaea the bacteria and the eukarya. The three domains are the archaea the bacteria and the eukarya.
They are grouped into five main categories. This phylum contains the largest group of bacteria and includes e coli salmonella heliobacter pylori and vibrio. Microorganisms are found in each of the three domains of life.
Bacteria have a unique cell wall composition and rrna type. Some bacteria have a unique type of rotating flagellum. There are many shapes that bacteria can come in but three of the main ones are cocci bacilli and spirochete.
