Lesson Details
Key learning points
- Growth is part of the life cycle of all living organisms.
- Multicellular organisms grow by making new cells.
- Multicellular organisms need to repair tissue through cell division.
- All new cells are made when existing cells copy their genetic material and then divide in two.
Common misconception
Multicellular organisms reproduce by cell division like unicellular organisms.
Multicellular organisms use cell division for reproduction. A non-example will be used to show reproduction is not part of reproduction in multicellular organisms.
Keywords
Growth - Multicellular organisms grow by increasing the number of cells they have; this involves cell division.
Unicellular - An organism that consists of only one cell.
Multicellular - An organism made up of many cells.
Cell division - The process by which cells replicate to produce two genetically identical cells.
