Plant cells and animal cells: how they are alike and different

Grade 7 Science Worksheet

NameDate

Circle the best answer.

  1. It has no chloroplasts. Ari reads a cell card. Which conclusion is right?

    • A plant cell, because it has a cell wall and a large central vacuole
    • An animal cell, because it has no chloroplasts
    • An animal cell, because roots grow underground
    • A plant cell, but it cannot release energy from sugar without chloroplasts

  2. Bo reads a cell card. Which conclusion is right?

    • A plant cell, because it has mitochondria to use energy
    • Not a cell, because it has no cell wall
    • An animal cell, because it has a membrane but no wall or chloroplasts
    • A plant cell, because its membrane is a thin cell wall

  3. Read this first

    Microscope card (read about; the teacher prepared the slide)

    Cheek cells, stained blue. Flat cells with uneven, rounded edges, one dark dot in each cell, no thick outer line. Not to scale.

  4. Kira’s teacher shows a prepared slide through a microscope. Why do these cells have uneven, rounded shapes?

    • They have no edge around the cytoplasm
    • They are not true cells, because they have no cell wall
    • They have a soft cell wall that bends
    • They have a flexible membrane and no stiff cell wall

  5. Microscope card (read about; the teacher prepared the slide): a leaf of a water plant. Not to scale. Luz’s teacher shows a prepared slide through a microscope. Which two parts seen here show these are plant cells?

    • The cell walls and the chloroplasts
    • The mitochondria and the nucleus
    • The cell walls, which replace the membranes
    • The cell membrane and the cytoplasm

  6. “Student drawing of a leaf cell, not to scale, with each part named:” Milo drew a typical leaf cell and left out one part. Which part is missing?

    • Nothing: plant cells have no mitochondria
    • Nothing: the chloroplasts handle the cell’s energy
    • A second cell wall inside the membrane
    • Mitochondria

  7. Noah drew an animal cell and left out one part. Which part is missing?

    • A nucleus
    • A cell wall around the outside
    • A stiff wall to hold its shape
    • Chloroplasts

  8. Cell wall, cytoplasm, nucleus, mitochondria, chloroplasts, large central vacuole. Pia drew a typical leaf cell and left out one part. Which part is missing?

    • A cell membrane just inside the cell wall
    • Nothing: membranes belong in animal cells, not plant cells
    • A second nucleus
    • Nothing: the cell wall does the membrane’s job

  9. Cell theory card

    (1) All living things are made of one or more cells. (2) The cell is the basic living unit. (3) New cells come only from cells that already exist. Growth table (example data): Day 1, root 2 cm; Day 3, root 4 cm; Day 5, root 7 cm.

  10. Ren measures a bean seedling’s root, which grows longer each day. Where do the new root cells come from?

    • The old cells stretch longer; no new cells form
    • The soil turns into new root cells
    • Water in the root turns into cells
    • Existing root cells divide to make new ones

  11. Cell theory card

    (1) All living things are made of one or more cells. (2) The cell is the basic living unit. (3) New cells come only from cells that already exist. Note: the pond water holds a living thing made of just one cell.

  12. Tala’s class reads about a pond water sample. Which statement fits cell theory?

    • It formed from pond water and mud
    • It is alive, but it is not made of cells
    • It is alive, and its one cell does all of its life processes
    • It is too small to be alive, so it is not considered a living thing

  13. Cell theory card

    (1) All living things are made of one or more cells. (2) The cell is the basic living unit. (3) New cells come only from cells that already exist.

  14. Zee reads that a tadpole grows into a frog with many more cells. Where did the extra cells come from?

    • From its food turning straight into new cells
    • From its existing cells dividing again and again
    • From the pond water it swims in
    • Frogs are made of cells, but tadpoles are not

About this worksheet

Plant cells and animal cells. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can name the parts that plant and animal cells share (cell membrane, cytoplasm, nucleus, mitochondria) and the parts only plant cells have (cell wall, large central vacuole, and in green parts chloroplasts).
  • I can tell a plant cell from an animal cell from a drawing, a parts chart, a cell card or a microscope view, and say which part decides it.
  • I can use the three parts of cell theory to explain where new cells come from and what is made of cells.

Standard: MS-LS1-1, MS-LS1-2

Words to know

cell: The smallest unit of a living thing that is itself alive

cell membrane: The thin, flexible outer edge of a cell; in plants, just inside the wall

cell wall: A stiff layer outside the membrane of plant cells; it supports and shapes them

cytoplasm: The jelly-like inside of a cell, where its other parts sit

nucleus: The part that holds the cell's DNA and directs the cell

mitochondria: Parts that release energy from sugar; in plant and animal cells

chloroplasts: Green parts in some plant cells that make sugar using light

large central vacuole: A big sac in plant cells that stores water and keeps the cell firm

Common mistakes

Your child thought plant cells have no mitochondria, or get all their energy from chloroplasts. Try this: chloroplasts make sugar, and mitochondria in the same cell release its energy, day and night.

Your child thought a plant cell has a cell wall instead of a cell membrane. Ask your child to draw a box inside a box: the wall outside, the membrane just inside it.

Your child thought animal cells have a cell wall, or that the outer edge of an animal cell is a wall. Ask your child which cells keep a stiff, boxy shape and why.

Questions parents ask

What is the most common mistake with plant cells and animal cells: how they are alike and different?

Your child thought plant cells have no mitochondria, or get all their energy from chloroplasts. Try this: chloroplasts make sugar, and mitochondria in the same cell release its energy, day and night.
