Stem Cells

• What are stem cells?

  Cells that can divide and differentiate
• What are the two key features of stem cells?

  They divide by mitosis and differentiate
• How do stem cells divide?

  By mitosis to form more cells
• How does the differentiation of stem cells contribute to human development?

  It allows formation of specialized cells from one cell
• What is the first cell formed after fertilization?

  A zygote
• What are embryonic stem cells capable of?

  They can differentiate into any cell type
• What happens to embryonic stem cells as development progresses?

  They differentiate into specialized cells
• What type of stem cells are found in adult organisms?

  Adult stem cells
• What is the limitation of adult stem cells compared to embryonic stem cells?

  They can only differentiate into a narrow range of cells
• Where are adult stem cells primarily found?

  In bone marrow
• Where are plant stem cells located?

  In meristem tissue
• What is the function of adult stem cells?

  To replace damaged cells
• What is the role of plant stem cells?

  To differentiate into all necessary plant cells
• How do plant stem cells differ from embryonic stem cells?

  Plant stem cells persist throughout the plant's life
• What are the types of stem cells discussed in the video?

  • Embryonic stem cells
  • Adult stem cells
  • Plant stem cells
• What are the key differences between embryonic and adult stem cells?

  • Embryonic stem cells can differentiate into any cell type.
  • Adult stem cells can only differentiate into a limited range of cells.
  • Embryonic stem cells are present early in development.
  • Adult stem cells are found in specific tissues like bone marrow.
• What types of cells can adult stem cells differentiate into?

  • Red blood cells
  • White blood cells
  • Platelets
• What types of cells can plant stem cells differentiate into?

  • Palisade cells
  • Phloem cells
  • Xylem cells
  • Root hair cells
