Which is a reason for humans being in Kingdom Animalia?
Think it through first, then pick an option.
- a complex tissue system
- b simple tissue system
- c autotrophic
- d prokaryotic
Answer and explanation
Correct answer: a complex tissue system
The book says humans are Animalia because of eukaryotic cells, multicellularity, heterotrophy and a complex tissue system.
Why the other options are wrong
- b simple tissue system: Humans have a complex tissue system, not a simple one.
- c autotrophic: Humans are heterotrophs; with no plastids they cannot make food.
- d prokaryotic: Human cells are eukaryotic; prokaryotic cells belong to Monera.
