Life consists of three domains; Archaea, Bacteria and Eukarya. Of these domains, Archaea and Bacteria consist exclusively of single celled organisms. Additionally, one of the four kingdoms of Eukarya, i.e. Protista, consists of single celled organisms.So single celled organisms could be referred to as Archaea, Bacteria and Protista.
The statement which best compares a multicellular organism to a single-celled organism is their functions. While multicellular organisms use organ systems to perform life functions, single-celled organisms do not use organs for the life functions.
Single-celled organisms are also called unicellular organisms, as they consist of only one cell that performs all the necessary functions of life.
Life on Earth began about 3.8 billion years ago, initially with single-celled prokaryotic cells, such as bacteria.
amoeba are a single celled life form, a single celled organism and measured to be around 0.25 mm!
An amoeba defines life through its ability to grow, reproduce, respond to stimuli, and maintain homeostasis. These single-celled organisms also exhibit movement, metabolism, and the ability to adapt to their environment, which are characteristics of life.
The first forms of life were single-celled amoeba - these rapidly evolved into many multicellular organisms eventually giving rise to the human race.
what is a single celled organism that can carry on all its life
Parmamecium has a definite shape and slides through water while Amoeba is a single celled organism that has no definite shape and consisting of a mass of protoplasm containing one or more nuclei surrounded by a flexible out membrane.

AmoebaIf it is in ponds it is found moving about around the weeds and stones. Some species are found in the damping soil. Amoeba is a protist, so it is a microscopic in size , measuring 0.25 millimeters. It is a single celled life formIt Is also a single celled organism.

A single celled animal is an animal that only has one cell, Eg: amoeba, Paramecium, Euglena, Chlamydomonas. Single celled animals have one cell that does all of its life processes, such as ingestion, movement, excretion, reproduction. A multi-celled animal is an animal that has many cells that each perform a specific function of life. These animals have a group of cells that digest, another group reporduces, another group controls movement, etc. If you look in the Wikipedia, it offers good information as well. Hope this helps :-)

there are many functions of the amebaif you type ameba into the search engin you shall get the answerThaanks :DAn amoeba is a single celled life form that has an irregular shape. Its function is to break down the bacteria that comes from plants that decompose.
