   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

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

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

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

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

   • Both have cell walls
   • Neither makes its own food
   • Both make food from sunlight

   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 not cells
   • They are a sixth kingdom of cells
   • They are part of the plant kingdom

    • The virus is a cell; the bacterium is not
11. 10.

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