Answer 1

Unicellular organisms have only 1 cell.

Eg:- Amoeba, paramecium, etc

Multicellular organisms have more than 1 cell.

Eg:-Hydra, human

Answer 2

Answer:

Explanation:

Unicellular Organisms:

Unicellular creatures, as the name indicates, are made up of a single cell. They are the most ancient form of life, with fossil records reaching back to around 3.8 billion years. Unicellular creatures include bacteria, amoeba, Paramecium, archaea, protozoa, unicellular algae, and unicellular fungus. Because these unicellular creatures are generally undetectable to the human eye, they are sometimes known as microscopic organisms. The majority of unicellular creatures are also prokaryotes.

Some of the examples of unicellular organisms are:

• Amoeba

• Euglena

• Paramecium

• Plasmodium

• Nostoc, Salmonella ( Prokaryotic unicellular organisms)

• Protozoans, Fungi, Algae ( Eukaryotic unicellular organisms).

Multicellular Organisms:

Multicellular organisms are creatures that are made up of more than one cell. Eukaryotes are nearly invariably multicellular creatures. Bacteria, on the other hand, may develop enormous interconnected structures such as colonies or biofilms, but they are not multicellular creatures.

Some of the examples of multicellular organisms are:

• All vertebrates and invertebrates

• All angiosperms, gymnosperms and higher land plants.
