What are the three domains of living things?

Three domains of living things are :-

1- Archaea

2- Bacteria

3- Eukarya

Explanation: Domain system divide living things into three domains. Each of domain contain unique features.  Phylogenetic tree of life gives understanding about living things.

Features of these three domains are given below -

1. Archaea :- Archaea are prokaryotes. They live in extreme conditions as they live extreme salty conditions and they live in extreme temperature conditions.

2- Bacteria - Bacteria are prokaryotes. Cell wall is made up of peptidoglycane which is distinct from Archaea and Eukarya.

3-Eukarya - These are eukaryotes. Not all Eukarya contain cell wall.
