Likely, they were some sort of colony-organism, like Volvox today. Such organisms will exist as single cells for most of the time, but form colonies, aggregates of many thousands of cells, when under stress, for instance from predation or lack of food.
Yes! All multi-cellular organisms contain specialized cells. Specialization is the reason they become multi-cellular. Multi-cellular organisms are differentiated from other eukaria and prokaria in that, rather than living individually or in convenient colonies, they MUST be multi-cellular to survive.
Multi cellular organisms are more complicated than unicellular organisms.
yes
No, I am a multi-cellular organism.
multicellular organisms are made of multiple cells but uni cellular organisms have one multicellular organisms are made of multiple cells but uni cellular organisms have one cell multi cells humans, plant, dog uni cell are moss, fungus, mushrooms by shetroom
multi-cellular
Yes.
It can be strong
multi-cellular
they are multi-cellular organisms, primary consumers, and vertebrates
Bacteria are single-celled organisms, making them unicellular. They do not have a nucleus or other membrane-bound organelles like multi-cellular organisms do.
Bacteria are uni-cellular, meaning they are all single celled organisms.
