🌱 Stem Cells & Regeneration
Explore the fascinating world of stem cells—the body's "blank slate" cells that can divide indefinitely and transform into specialized cell types. This quiz examines the unique properties of stem cells, the differences between embryonic and adult stem cells, and how scientists are harnessing their regenerative potential to treat diseases and repair damaged tissues. Perfect for Grade 8 students diving deep into cellular biology. **What you'll learn:** - How stem cells differ from regular cells in structure and function - Why embryonic and adult stem cells have different regenerative capabilities - Real-world medical applications of stem cell therapy - Current challenges and ethical considerations in stem cell research
