• A. Skin
• B. Heart
• C. Stem
• D. Red blood

Answer: (C)

Verified step by step guidance

1. Understand the context of the problem: The question is asking about a type of cell that develops during the germinal period and has the potential to grow new organs or tissues.
2. Identify the germinal period: This is the first two weeks of prenatal development after conception, characterized by rapid cell division and the beginning of cell differentiation.
3. Recognize the role of stem cells: Stem cells are undifferentiated cells that have the potential to develop into different cell types in the body. They are crucial during early development and for regenerative medicine.
4. Differentiate between the options: Skin, heart, and red blood cells are specialized cells that do not have the same potential for differentiation as stem cells.
5. Conclude that stem cells are the correct answer: They are the only type of cell listed that can develop into various cell types and are involved in early development during the germinal period.
