Multicellular and unicellular organisms
I can explain the differences between multicellular and unicellular organisms.
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.
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.
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.
