Plant cell against animal cell 8

  • A detective tells the two cells apart from three clues Clue one: a cell wall outside the membrane. Clue two: green chloroplasts. Clue three: one large vacuole. All three mean a plant cell. Both suspects have a nucleus with the instructions, a membrane that decides what crosses, mitochondria for energy and ribosomes that build proteins.
  • A plant cell and an animal cell trade homes for a day Both: a nucleus that holds the instructions, a membrane that decides what crosses, mitochondria that supply the energy, ribosomes that build proteins. Plant cell only: a stiff cell wall, chloroplasts and one large vacuole.
  • A sleepover where each cell shows the other around Animal cell's tour: nucleus with the instructions, membrane that decides what crosses, mitochondria for energy, ribosomes building proteins. Plant cell's tour: all of those, then the cell wall, the chloroplasts and the large vacuole.
  • A talent show: one makes its own sugar, one cannot Plant cell: chloroplasts make sugar from light. Animal cell: has none and must take food in. Both: mitochondria turn food into usable energy, the nucleus holds the instructions, ribosomes build proteins, the membrane decides what crosses.
  • Moving day: what is in each cell's boxes Both unpack: a nucleus with the instructions, a membrane that decides what crosses, mitochondria for energy, ribosomes to build proteins. The plant cell unpacks three more: a cell wall, chloroplasts and a large vacuole full of water.
  • Pen pals: a leaf cell writes to a cheek cell Leaf cell: 'I have a wall, chloroplasts and a big vacuole.' Cheek cell: 'I have none of those.' Both: 'My nucleus holds the instructions, my membrane decides what crosses, my mitochondria supply the energy, my ribosomes build proteins.'
  • Sports day: the plant cell stands firm, the other bends Plant cell: a cell wall and a full vacuole keep it firm. Animal cell: a membrane with no wall. Both teams: a nucleus holding the instructions, a membrane deciding what crosses, mitochondria supplying the energy, ribosomes building proteins.
  • Two neighbors argue over who needs a wall Plant cell: has a cell wall outside its membrane, for support. Animal cell: has the membrane alone. Both: the membrane decides what crosses, the nucleus holds the instructions, mitochondria supply the energy, ribosomes build proteins.

How it works

These cell story ideas are premises for the assignment to write a story about a cell. Each casts the parts as characters or places and gives every part its real job, in the order the story meets it.

Read the full guide

Four parts every story needs

Each idea names at least these four with their jobs. The nucleus holds the instructions. The cell membrane decides what crosses into and out of the cell. The mitochondria supply the energy the cell uses. The ribosomes build proteins. Some ideas add the Golgi body, which packages proteins, or the lysosomes, which break down worn-out parts.

Pick the kind of story

The cell as a place turns the whole cell into a city, a ship or a kitchen. A day in the life follows one part. Something goes wrong stops one job and shows what depends on it. Plant cell against animal cell adds the wall, the chloroplasts and the large vacuole.

  • Underline each part's name the first time it appears, with its job in the same sentence.
  • A story about something going wrong shows a job most clearly: stop it and write what happens next.

Questions and answers

How do you write a story about a cell?

Turn the cell into a place or a cast of characters and give every part its real job. Start with a problem, such as a big delivery or a strike at the power stations, and let each part act in turn.

What can a cell be compared to in a story?

A city, a school, a sailing ship, a restaurant kitchen, a castle, a space station, a factory or an airport. In each, something guards the edge, something holds the instructions, something supplies the energy and something builds.

What are the main parts of a cell and their jobs?

The nucleus holds the genetic instructions. The cell membrane controls what enters and leaves. Mitochondria supply most of the cell's usable energy. Ribosomes build proteins. The Golgi body packages proteins, and lysosomes break down worn-out parts.

How is a plant cell different from an animal cell?

A plant cell has a cell wall outside its membrane, chloroplasts that make sugar from light, and one large vacuole. An animal cell has no cell wall and no chloroplasts. Both have a nucleus, a membrane, mitochondria and ribosomes.
