Question

differentiate between unicellular and multicellular organisms ​

Answer 1

unicellular: organism with single cell

multicellular: organism with more than one cell

Answer 2

Answer:

Unicellular organisms :

They are simple, minute, single-celled organisms, made up of a single cell which existed about 3.8 million years ago. Bacteria, amoeba, Paramecium archaea, protozoa, unicellular algae, and unicellular fungi are the main groups of unicellular organisms. These unicellular organisms are mostly invisible to the naked eye, hence, they are also referred to as microscopic organisms. Most of the unicellular organisms are prokaryotes.

Unicellular Organisms Examples

Some of the examples of unicellular organisms are:

Amoeba

Paramecium

Plasmodium

Euglena

Nostoc, Salmonella ( Prokaryotic Unicellular organisms)

Protozoans, Fungi, Algae ( Eukaryotic Unicellular organisms)

Multicellular organisms :

Organisms which are composed of multiple cells are called multicellular organisms. These cells are attached to each other to procedure a multicellular organism. Most of these cells are visible to the naked eye. Organisms including, animals, birds, plants, humans are the main groups of a multicellular organism. Most of the multicellular organisms are eukaryotes.

Multicellular Organisms Examples

Some of the examples of multicellular organisms are listed below:

Animal – Hydra

Plant – Spirogyra

Cyanobacteria such as Chara (Multicellular prokaryotic organisms)

Species of gymnosperms and angiosperm plants (Multicellular eukaryotic organisms)
