📋 What Are Stem Cells?
- Definition: Undifferentiated cells that can divide to produce more stem cells (self-renewal) or differentiate into specialized cell types
- Key characteristics:
- High capacity for cell division (self-renewal)
- Ability to differentiate into multiple cell types
- Ability to self-renew to maintain the stem cell pool
- Location: Found in embryos, adult tissues, and plant meristems
Quick Check: What are the TWO key properties of all stem cells?
1. Self-renewal — they can divide to produce more stem cells. 2. Differentiation — they can develop into one or more specialised cell types.

What does 'totipotent' mean?
The highest level of potency - cells can differentiate into any cell type in the organism plus extraembryonic tissues like the placenta. Example: fertilized egg.
