   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 two kingdoms both have cell walls and many cells, Ari?

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

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

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

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

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

   A fuzzy growth on a fallen leaf has many cells and chitin walls, and it absorbs food from the leaf. Which kingdom fits, Kira?

   • Animals
   • Plants, as it grows on a leaf
   • Protists
   • Fungi
7. 6.

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

   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?

   • Each of them
   • The yeast
   • The amoeba
   • The soil bacterium
10. 9.

    Living things are made of cells and grow and use energy on their own. Why are viruses not placed in any kingdom, Ren?

    • They are too small bacteria
    • They are a sixth kingdom of cells
    • They are part of the plant kingdom
    • They are not cells
11. 10.

    Tala compares a bacterium and a virus. Which statement is right?

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