Plants also have stem cells, but they work differently from animal stem cells:
| Feature | Animal Stem Cells | Plant Meristems |
|---|---|---|
| Location | Scattered in specific tissues | Growing tips (apical) and cambium (lateral) |
| Differentiation | Often irreversible | More flexible - can dedifferentiate |
| Totipotency | Lost after early embryonic stage | Many plant cells remain totipotent throughout life |
| Growth pattern | Determinate (stops at maturity) | Indeterminate (continuous growth) |
This diagram covers Plant Stem Cells: Meristems within Stem Cells and Cell Differentiation for GCSE Biology. Stem cell types, differentiation processes, therapeutic applications, embryonic vs adult stem cells, and ethical considerations It is section 6 of 17 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
Practice questions for Stem Cells and Cell Differentiation
What is a stem cell?
Explain how sperm cells are adapted for their function.
Quick recall flashcards
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.
What is a stem cell?
An undifferentiated cell that can divide to produce more stem cells (self-renewal) or differentiate into specialized cell types.
