   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.

   • Plants and animals
   • Animals and fungi
   • Bacteria and animals
3. 2.

   Using the chart, what do bacteria and protists have in common, Bo?

   • Both have chitin walls
   • Most are a single cell
   • Both have a nucleus
   • Neither has a nucleus
4. 3.

   Using the chart, which trait do fungi and animals share, Esme?

   • Neither makes its own food
   • Both have cell walls
   • Both make food from sunlight
   • Both are a single cell
5. 4.

   A pond organism is one cell with a nucleus. It has green chloroplasts and swims. Which kingdom fits, Jun?

   • Bacteria
   • Plants, as it is green
   • Protists
   • Animals, as it swims
6. 5.

   A sample has tiny single cells with no nucleus that swim with tails. Which kingdom fits, Luz?

   • Bacteria
   • Animals, as they swim

   Pia sorts one-celled organisms: an amoeba (has a nucleus), a soil bacterium (no nucleus) and a yeast (has a nucleus, chitin wall). Which is a protist?

   • The amoeba
   • The yeast

    • The bacterium is a cell; the virus is not
    • Neither has genetic material
    • The virus is a cell; the bacterium is not
    • Both are cells
11. 10.

    Which property of life does a virus lack on its own, Zee?

    • It can't split in two like other cells
    • It has no shape
    • It has no size
    • It can't copy itself outside a host cell
