What are the advantages of being multicellular rather than unicellular?

• Prokaryotic cells can work together

• Unicellular eukaryotes can behave as a single organism

• Multicellularity means greater competitive advantage

• Multicellularity means specialization

How do prokaryotes work together?

• Individuals form colonies

• Individuals compete against each other for resources

• Colonies compete against individuals

• Individuals become multicellular

Unicellular __________ can behave as a single organism.

• Eukaryotes

• Prokaryotes

• Bacterium

• Animals

How does multicellularity provide a greater competitive advantage?

• Living as a large colony gives a unicellular organism an advantage over single celled organisms.

• Some unicellular eukaryotes spend some of their life cycle as singular independent cells.

• Most prokaryotic cells behave as individuals.

• Multicellularity makes all cells exactly the same.

How does multicellularity lead to specialization?

• Having multiple cells means that certain cells can be specialized for a specific task.

• All cells copy each other to become the same and work together.

• Each cell is completely different from the other.

• The cells compete for the best cell. Only the best cell survives.

Given that a newborn baby has about 2 trillion cells, how many times does the zygote (the original cell) have to divide to reach this?

• 1,000,0000

• 41

• 185

• 1,000,000,000
