S3.1.4 For the adult
What each part does
What job does each part of a cell do?
What this chapter teaches
Each part of a cell has a job. The nucleus controls the cell. The membrane decides what goes in and out. The cell wall gives a plant cell its shape. Chloroplasts need light to make food, so roots have none.
Three questions to ask
There is no one right wording. Listen for the idea.
- What does the nucleus do? What does the cell membrane do?
- Why does a plant that has too little water go limp?
- Why do the cells in a root have no chloroplasts?
After the chapter, the learner can
- Explain the job of the nucleus, membrane and cell wall
- Explain why only green plant cells have chloroplasts
What they copy into their notebook
The nucleus controls the cell. The membrane decides what goes in and out. The cell wall gives a plant cell its shape. Chloroplasts use light to make food, so only green parts have them.
