What was the first multicellular organism?
The earliest fossils of multicellular organisms include the contested Grypania spiralis and the fossils of the black shales of the Palaeoproterozoic Francevillian Group Fossil B Formation in Gabon (Gabonionta). The Doushantuo Formation has yielded 600 million year old microfossils with evidence of multicellular traits.
How do systems work in a multicellular organism?
Key points. Humans—and other complex multicellular organisms—have systems of organs that work together , carrying out processes that keep us alive. The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
What keeps multicellular organisms alive?
For any multicellular organism to survive, different cells must work together . ... In animals, skin cells provide protec- tion, nerve cells carry signals, and muscle cells produce movement. Cells of the same type are organized into a group of cells that work together.

What are Class 9 multicellular organisms?
(II) Multicellular organisms- These are the organisms that contain more than one cell . Animals, plants, and most of the fungi are multicellular. These organisms arise by cell division or aggregation of many single cells. Examples of some Multicellular Organisms: Humans, Horse, Trees, Dogs, Cows, Chicken, Cats.
Are bacteria multicellular?
Highlights. Many bacteria have a multicellular phase of their lifecycle , which fall into three broad categories based on shape and mechanism of formation. A number of pressures may have selected for multicellularity, including physicochemical stress, nutrient scarcity, predation, and environmental variability.
