Lesson Details
Key learning points
- All organisms (including animals, plants, fungi and micro-organisms) are made up of one or more living cells.
- All cells have some structures in common (cell membrane and cytoplasm) and have a three-dimensional shape.
- Chemical reactions essential to life occur in cytoplasm; the cell membrane regulates the cell’s internal environment.
- Many animals and plants are multicellular; they are made up of many cells organised to form tissues and organs.
- Micro-organisms such as bacteria are unicellular – they are made of just one cell.
Common misconception
Pupils may think that all animals and plant are multicellular and that all unicellular organisms are bacteria.
Lesson explicitly addresses this misconception and the questions in Task A are designed to expose the misconception.
Keywords
