The correct answer to the given question about One - celled organisms is option 3) 100X
An organism that only has one cell is referred to as a unicellular organism, or single-celled organism, as opposed to a multicellular organism, which has numerous cells. Prokaryotic and eukaryotic organisms are the two broad classifications of creatures. Bacteria and archaea are the two divisions of prokaryotes, which are all unicellular organisms. While most eukaryotes have several cells, some, like protozoa, single-celled algae, and single-celled fungi, have only one cell. With early protocells likely developing 3.8–4.0 billion years ago, unicellular creatures are regarded to be the oldest form of life. Prokaryotes can form colonies, but they are not specialized cells with distinct roles. These organisms coexist, and in order to survive, each cell must perform every function necessary for existence.
