Question

How are the three domains of life-related to each other?

Answer 1

The three domains of life are bacteria domain, archaea domain, and eukarya domain which is important for the life on earth and the environment, ecosystem, climate, food chain, and many more factors which are dependent on these three domains as these organisms are interrelated to each other.

Complete answer:
This classification of three domains is done based on the type of cell of the organism as bacteria cells are the type of cells that do not contain a nucleus, archaea cells are the type of cells that do not contain a nucleus but they compose different cell wall from the bacteria and eukarya are the type of cells that contain a nucleus.

Archaea and bacteria cells have many similarities between them as they both are single-celled organisms and are of small size and these domains contain species that reproduce asexually and are composed of prokaryotic cells and archaea live in hot springs type extreme environment but bacteria do not live in this environment.

As the eukarya domain has a nucleus so this posse’s different space among two domains and the species included in this domain have their genetic material in the DNA and this domain includes kingdoms like Plantae, Fungi, Animalia, and Protista.

Note: This paradigm of three domains is proposed by Woese, kandler, and wheelis and according to the 16s RNA system this is the tree that is divided into three domains of life. The current accepted model is that the origin of the eukaryotic cells are based on archeal cell and bacterial cells fused into a single which gave rise to the eukaryotic species.
