    • Archaea: no nucleus, no peptidoglycan, ether-linked lipids
    • Bacteria: no nucleus, which is enough to place it in Bacteria
    • Plantae: a cell like this belongs to the plant kingdom

  15. Ren reads a card for two model plants. Which statement follows from the card?

    • They share a class, so they must share an order too
    • They share a class, so they share the phylum, kingdom and domain too
    • They differ in order, so they cannot share a domain
    • They share a class, so they must share a genus too

    • Canidae, the family below class
    • Chordata, the phylum above class
    • Canis, the genus below class
    • Plantae, a kingdom that holds both
  18. “Tree (real groups, not to scale):” Zee reads a nested tree. What is the smallest named group on it that holds both the dog and the garden pea?
