Which cell parts are in plant cells, animal cells or both?

Cells, genetics and evolution

CCSS NGSS.MS-LS1-1CCSS NGSS.MS-LS1-2England: KS3 Biology: Cells and organisation

Objective and success criteria

Students will: Which cell parts are in plant cells, animal cells or both?.

  • I can answer questions on today's skill on my own, without help.
  • I can explain each step and say why it works.
  • I can check my answer and spot a mistake.

Before and after

Needs first: Plant and animal cells

Leads to: the next skill in this area.

Materials: Microscope images or slides, Cell diagrams, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).

Warm-up · 4 min

  • Quick retrieval from earlier learning (Plant and animal cells). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. Which part of a cell contains chlorophyll? (cell wall / chloroplasts / cell membrane / mitochondria) → chloroplastsPrompt: Think about which parts are only in plant cells.
  2. Cells: which statement is NOT true? (Plant cells have a cell wall but animal cells do not. / Animal cells have a cell wall. / Chloroplasts are found in plant cells, not animal cells. / Both plant and animal cells have a nucleus, cytoplasm and a cell membrane.) → Animal cells have a cell wall.Prompt: Do plant cells respire?
  3. Which part of a cell releases energy from glucose? (chloroplasts / cell membrane / cell wall / mitochondria) → mitochondriaPrompt: Think about which parts are only in plant cells.

Hook · 3 min

  • Show a microscope image of cells and ask what students think they are looking at.
  • Share the objective: Which cell parts are in plant cells, animal cells or both?. Read the success criteria together.

I do: model it · 7 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: Where is this found: cell membrane?
  • Step 1: Nucleus, cell membrane, cytoplasm, mitochondria and ribosomes are in both.
  • Step 2: So the answer is: both plant and animal cells
  • Answer: both plant and animal cells
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 6 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. Where is this found: cell wall? (plant cells only / both plant and animal cells) → plant cells onlyPrompt: Plant cells have everything animal cells have, plus some extras.
  2. A cell sample has a nucleus, cell membrane and mitochondria, but no cell wall. It is most likely from… (an onion skin / a leaf / an animal, such as a cheek swab / a moss plant) → an animal, such as a cheek swabPrompt: Which type of cell never has a cell wall?

You do: independent practice · 7 min

  • Students work on the student sheet. Circulate and check the first two answers of every student early.
  • Students who finish: write a question of their own for a partner, with the answer.

The 6 questions are on the student sheet below, with answers in the key.

Exit ticket · 3 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. Why do animal cells not need a cell wall? (Animals are supported by skeletons and their cells need to be flexible / Animal cells have chloroplasts instead / Walls would stop all substances entering / Animal cells are too small for walls) → Animals are supported by skeletons and their cells need to be flexiblePrompt: What supports an animal's body?
  2. Where is this found: cell membrane? (plant cells only / both plant and animal cells) → both plant and animal cellsPrompt: Plant cells have everything animal cells have, plus some extras.

Watch out for

  • Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
  • Remembering facts without the reason: ask "why?" and "what is the evidence?"

Support and stretch

Support

  • Review first: Plant and animal cells.
  • Use concrete materials: microscope images or slides.
  • Give the first step of each question, or a partly worked example to finish.
  • Pair with a confident partner for the guided practice.

Stretch

  • Explain a common mistake in writing and how to fix it.
  • Write a word problem that uses today's skill, then solve a partner's.
