   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, what do bacteria and protists have in common, Bo?

   • Most are a single cell
   • Neither has a nucleus
   • Both have chitin walls
   • Both have a nucleus
3. 2.

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

   • Neither makes its own food
   • Both have cell walls
   • Both are a single cell
   • Both make food from sunlight
4. 3.

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

   • Protists
   • Animals, as it swims
   • Bacteria
   • Plants, as it is green
5. 4.

   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
   • Fungi
   • Protists
   • Plants, as it grows on a leaf
6. 5.

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

   • Fungi
   • Bacteria
   • Protists, as they are one cell
   • Animals, as they swim
7. 6.

   Milo sorts a list: moss, yeast, sunflower, mold, fern. Which ones are fungi?

   • Sunflower and fern
   • Yeast and mold
   • Yeast, mold and moss
   • Moss and mold
8. 7.

   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 yeast
   • The amoeba
   • The soil bacterium
   • Each of them
9. 8.

   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 a sixth kingdom of cells
   • They are too small bacteria
   • They are part of the plant kingdom
   • They are not cells
10. 9.

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

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