The largest known unicellular organisms known are the Xenophyophores. At up to 20 centimeters in diameter, Syringammina fragilissima is one of the largest of these. They are deep sea dwelling bottom feeders. For more information, see the related link.
The smallest creature in the world is either a virus, if you count microbes that or a fairy fly.A fairy fly is actually a bee but does not sting us.It is under 0.5mm long! If you count smaller-than-microbes,people say an atom is the smallest. this is .not true. atoms are made up of the nucleus, and the electrons. the electrons are made up of even smaller particles called quarks(nothing to do with ducks). However, the quarks are made of smaller particles unknown to man. even though the electrons are made up of quarks, they are made up of gluons as well. these gluons are an elemental element. this means they are not made up of anything else. By the way, a virus is, in fact, alive. here's what it does for a living.......... virus enters cell. it programs the cell to use all it's energy to make more viruses. cell dies. all microbes move onto next victim. virus enters cell. it programs the cell to use all it's energy to make more viruses. cell dies. all microbes move onto next victim. virus enters cell. it programs the cell to use all it's energy to make more viruses. cell dies. all microbes move onto next victim. virus enters cell.........well there you go. special two in one question!!!
Bacteria.
It is so small that you cant even see it.
Ostreococcus is the smallest independent eukaryote with an average size of 0.8 µm.
It is bacteria
One-celled amoeba
an amoeba.
Both of them are living creatures, and both of them contains cell and respire, the blood circulate in their bodies.
the smallest cell that is life is the prokaryotic cell
Are maggots unicellular?
unicellular
A single celled organism is called unicellular.
Unicellular creatures. OR AMOEBA'S which are one celled animals.
unicellular creatures
Unicellular
Multicellular and unicellular are different because multicellular have more than one cell but a unicellular has only one cell.
Both of them are living creatures, and both of them contains cell and respire, the blood circulate in their bodies.
Unicellular algae is the smallest plant in a tropical rainforest
Unicellular... Umm... I think so
Bacteria are the smallest living creatures. Viruses are smaller but generally not considered living creatures.
cell is the smallest level of organization in a unicellular organism
FU
the smallest cell that is life is the prokaryotic cell
the smallest flying animal is the bee hummingbird
