    • What are the two unique properties of stem cells?
      Self-renewal and differentiation
    • Self-renewal refers to the ability of stem cells to undergo cell division while maintaining their undifferentiated state
    • Differentiation is the process of stem cells changing into specialized cells with specific functions.
    • Match the stem cell type with its differentiation potential:
      Totipotent ↔️ Any cell in the organism
      Pluripotent ↔️ Any cell in the embryo
      Multipotent ↔️ Limited range of cell types
    • What is an example of a totipotent cell?
      Zygote
    • Pluripotent cells can differentiate into any cell in the embryo, but not extra-embryonic cells.
    • Multipotent stem cells can differentiate into any cell type within the embryo.
      False
    • Which type of stem cell can form extra-embryonic tissues like the placenta?
      Totipotent
    • Order the stem cell types based on their differentiation potential from highest to lowest:
      1️⃣ Totipotent
      2️⃣ Pluripotent
      3️⃣ Multipotent
    • What is an example of a pluripotent cell?
      Inner cell mass of blastocyst
    • A totipotent cell can differentiate into any cell type in the organism.
    • Multipotent stem cells can differentiate into a limited range of cell types within a tissue or organ.
    • Why are totipotent cells considered the most versatile stem cells?
      They can form any cell type
    • Pluripotent cells can form extra-embryonic tissues like the placenta.
      False
    • What is an example of a multipotent cell?
      Hematopoietic stem cell
    • Pluripotent cells cannot form extra-embryonic tissues.
    • Match the stem cell type with its example:
      Totipotent ↔️ Zygote
      Pluripotent ↔️ Inner cell mass
      Multipotent ↔️ Hematopoietic stem cell
    • Order the roles of stem cells in tissue repair:
      1️⃣ Replace damaged cells
      2️⃣ Form new tissues
      3️⃣ Regenerate organs
    • What are the two key properties of stem cells that enable their role in development and tissue repair?
      Self-renewal and differentiation
    • During development, stem cells give rise to various cell types that form tissues and organs.
    • Stem cells in tissue repair help replace damaged or lost cells.
    • Match the role of stem cells with its description:
      Development ↔️ Stem cells differentiate into various cell types to form tissues and organs
      Tissue Repair ↔️ Stem cells replace damaged or lost cells to restore tissue function
    • What type of stem cells differentiate into blood cells to replace those lost due to injury or disease?
      Hematopoietic stem cells
    • Stem cell research raises several ethical considerations.
    • Why is the use of embryonic stem cells controversial in research?
      Destruction of embryos
    • Steps to ensure ethical standards in stem cell research
      1️⃣ Ethical oversight
      2️⃣ High ethical standards
      3️⃣ Respect for human dignity
      4️⃣ Protection of individuals from harm
    • Match the ethical consideration with its description:
      Source of Embryonic Stem Cells ↔️ The destruction of embryos to obtain embryonic stem cells is controversial.
      Potential Misuse ↔️ Stem cells could be used for non-medical enhancements, raising fairness concerns.
      Informed Consent ↔️ Patients must be fully informed about risks and benefits.
    • What are stem cells defined as in multicellular organisms?
      Undifferentiated cells
    • Self-renewal refers to the ability of stem cells to undergo cell division while maintaining their undifferentiated state.
    • What is the process called by which stem cells change into specialized cells with specific functions?
      Differentiation
    • Hematopoietic stem cells in bone marrow can differentiate into red blood cells, white blood cells, and platelets.
    • Match the stem cell type with its differentiation potential:
      Totipotent ↔️ Can differentiate into any cell in the organism
      Pluripotent ↔️ Can differentiate into any cell in the embryo
      Multipotent ↔️ Can differentiate into a limited range of cell types
    • Totipotent cells are the most versatile and can become any cell type in the organism.
    • Pluripotent cells can form extra-embryonic tissues like the placenta.
      False
    • What is an example of multipotent stem cells in the body?
      Hematopoietic stem cells
    • Totipotent cells are capable of becoming any cell type, including extra-embryonic tissues like the placenta
    • Pluripotent cells can form extra-embryonic tissues.
      False
    • Multipotent cells can differentiate into a limited set of cell types within a specific tissue
    • Which type of stem cell can differentiate into any cell in the organism, including extra-embryonic cells?
      Totipotent
    • Pluripotent cells can differentiate into any cell in the embryo
