Grade 7 Science Worksheet - Challenge Me

NameDate

Circle the best answer.

  1. Bo lists an amoeba, a paramecium, a soil bacterium and an alga cell. Which one belongs in a different kingdom?

    • The alga cell, as it is green
    • The amoeba, as it moves
    • The soil bacterium
    • The paramecium

  2. Esme lists a mold, a yeast, a mushroom and a sponge. Which one belongs in a different kingdom?

    • The sponge
    • The mushroom, as it is like a plant
    • The yeast, as it is one cell
    • The mold

  3. Kira says a one-celled organism that swims must be an animal. Agree or disagree?

    • Agree: anything that moves is an animal
    • Agree: swimming makes it an animal
    • Disagree: animals have many cells
    • Disagree: it must be a plant

  4. Luz says viruses are the smallest kind of bacteria. Agree or disagree?

    • Agree: both are one cell
    • Disagree: viruses are not cells
    • Agree: they are tiny bacteria
    • Disagree: viruses are protists

  5. Which single trait separates plants from fungi, Milo?

    • Whether it has a cell wall
    • Whether it has many cells
    • Whether it stays in one place
    • Whether it makes its own food

  6. Which single trait separates bacteria from protists, Noah?

    • Whether the cell has a nucleus
    • Whether it moves
    • Whether it is one cell
    • Whether it lives in water

  7. Which single trait separates animals from fungi, Pia?

    • Whether the cells have walls
    • Whether it has many cells
    • Whether it moves
    • Whether it makes its own food

  8. A new find is many-celled, has cellulose walls, is green and makes food from sunlight. Which kingdom fits, Ren?

    • Animals
    • Fungi, as it has walls
    • Protists, as it is green
    • Plants

  9. A new find is one cell with a nucleus and no wall, and it takes in food. Which kingdom fits, Tala?

    • Bacteria, as it is one cell
    • Animals, as it takes in food
    • Fungi
    • Protists

  10. A particle has genetic material in a protein coat and can copy itself only inside a host cell. Where does it belong, Zee?

    • Bacteria, as it is so small
    • Plants

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.
