   Comparison chart

   kingdom	cells	cell wall	food
   plants	many cells	yes (cellulose)	make their own by photosynthesis
   animals	many cells	no	take in food
   fungi	mostly many cells (yeasts one)	yes (chitin)	break food down outside the body and absorb it
   protists	mostly one cell	some	some make food and some take it in
   bacteria	one cell with no nucleus	most	some make food and most absorb it

2. 1.

   Using the chart, which kingdom has many cells, no cell wall and takes in food, Ari?

   • Animals
   • Bacteria
   • Plants
   • Fungi
3. 2.

   Using the chart, which kingdom has cell walls of chitin and absorbs its food, Bo?

   • Fungi
   • Animals
   • Protists
   • Plants, as they have walls too
4. 3.

   Using the chart, which kingdom is one cell with no nucleus, Esme?

   • Bacteria
   • Protists, as they are one cell too
   • Fungi
   • Plants
5. 4.

   Yeast makes Kira's bread dough rise. Yeast is a single cell with a chitin wall that absorbs sugar. Which kingdom is it in?

   • Fungi, as a one-celled fungus
   • Plants

   • Animals
6. 5.

   Under a microscope, Luz sees a one-celled pond creature with a nucleus swimming with a whip-like tail. Which kingdom is it in?

   • Bacteria, as it is one cell
   • Plants
   • Protists
   • Animals, as it swims

8. 7.

   Soil bacteria are single cells. Does a bacterium have a nucleus, Pia?

   • No

9. 8.

   Ren reads about viruses in a science book. Is a virus a cell?

   • Yes: a very small bacterium
   • Yes: a tiny plant
   • Yes: a kind of protist
   • No: it is not a cell
10. 9.

    How can a virus make more viruses, Tala?

    • By laying eggs
    • Only inside a host cell
    • By making food from sunlight
    • By splitting in two, like bacteria
11. 10.

    Most viruses are too small for a classroom microscope. What do scientists use to see them, Zee?

    • A telescope
    • A magnifying glass
    • A light microscope, like for bacteria
    • An electron microscope
