What are Stem Cells? Dif Betw Embryonic & Adult Stem Cells

• What are stem cells?

  Stem cells are undifferentiated cells that can divide and differentiate into specialized cells.
• Why are stem cells important?

  They can divide to form more cells and differentiate into specialized cells.
• What are the two key features of stem cells?


  • Ability to divide by mitosis to form more cells
  • Ability to differentiate into specialized cells
• What is the process called when a sperm cell fertilizes an egg cell?


  This process is called fertilization, forming a zygote.
• What is a zygote?

  A zygote is a single cell formed when a sperm cell fertilizes an egg cell.
• What are embryonic stem cells?

  Embryonic stem cells are cells that can differentiate into any type of cell in the body.
• How do embryonic stem cells differ from adult stem cells?

  Embryonic stem cells can differentiate into any type of cell, while adult stem cells can only differentiate into a narrow range of cells.
• Where are adult stem cells found?

  Adult stem cells are found in bone marrow.
• What types of cells can adult stem cells differentiate into?


  Adult stem cells can differentiate into different types of blood cells, such as red blood cells, white blood cells, and platelets.
• What is the role of adult stem cells in the body?

  Adult stem cells can replace damaged cells to maintain health but do not form new tissues.
• Where are plant stem cells found?

  Plant stem cells are found in meristematic tissue.
• What is the function of plant stem cells?


  Plant stem cells differentiate into all the cells and tissues that the plant needs for growth.
• What types of cells can plant stem cells differentiate into?

  Plant stem cells can differentiate into palisade cells, phloem, xylem cells, and root hair cells.
• How long do plant stem cells persist?

  Plant stem cells persist for the plant's entire life.
• What are the differences between embryonic stem cells and plant stem cells?

  • Embryonic stem cells can differentiate into any type of cell; plant stem cells differentiate into specific plant cells.
  • Embryonic stem cells disappear after development; plant stem cells persist throughout the plant's life.
