Lesson details
Key learning points
- Unicellular organisms are made of a single living cell.
- Multicellular organisms are made of more than one cell (sometimes millions), and different cells take on different jobs.
- In multicellular organisms, cells join together to form tissues with specific jobs.
- An organ is a group of tissues working together to do a specific job, and organs work together in an organ system.
- Unicellular organisms have different structures that have adaptations to help them function and stay alive.
Keywords
Unicellular - A unicellular organism is a living thing that is just one cell.
Multicellular - Multicellular organisms are made of lots of different types of cells.
Tissue - A tissue is a group of similar cells in the same place with the same job.
Organ - An organ is made up of a group of different tissues that work together to carry out a specific job.
Adaptation - An adaptation is a feature that helps an organism to function and survive.
Common misconception
There are only two types of cell: plant and animal.
The lesson explores the cells of unicellular organisms and some of their adaptations.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
