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

1.
Using the chart, which kingdom has many cells, no cell wall and takes in food, Ari?
- Animals
- Bacteria
- Plants
- Fungi
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
3.
Using the chart, which kingdom is one cell with no nucleus, Esme?
- Bacteria
- Protists, as they are one cell too
- Fungi
- Plants
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
- Bacteria, as it is one cell
- Animals
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
6.
Do the cells of an oak tree have cell walls, Noah?
- Yes, made of chitin
- No, like animal cells
- Yes, made of cellulose
7.
Soil bacteria are single cells. Does a bacterium have a nucleus, Pia?
- No
- Yes, two of them
- Yes, like a protist
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
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
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

About this worksheet

Sorting living things into kingdoms. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can sort an organism into one of five kingdoms from three traits: cells, cell wall and food.
I can tell fungi from plants, protists from bacteria, and animals from one-celled movers.
I can explain why a virus is not placed in any kingdom.

Standard: supports MS-LS1-1

Words to know

kingdom: A large group of living things that share key traits

cell wall: A stiff layer outside the membrane of some cells

nucleus: The part of a cell that holds its DNA, in a membrane

fungi: Mushrooms, molds and yeasts: they absorb food and have chitin walls

protist: A living thing, mostly one cell, with a nucleus, not a plant, animal or fungus

virus: Genetic material in a protein coat; not a cell

Common mistakes

Your child sorted a fungus, like a mushroom, as a plant. Fungi can't make their own food, and their cell walls are made of chitin.

Your child thought anything that moves is an animal. Many one-celled protists and bacteria move too.

Your child mixed up bacteria and protists. Both can be one cell, but bacteria have no nucleus and protists do.

Questions parents ask

What is the most common mistake with sorting living things into kingdoms?

Your child sorted a fungus, like a mushroom, as a plant. Fungi can't make their own food, and their cell walls are made of chitin.
