Cell Differentiation starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cell Differentiation.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A researcher is studying a population of cells that can give rise to all cell types in the body but not extraembryonic tissues. What type of stem cells are these?
A scientist observes that certain cells in a developing embryo begin to express muscle-specific proteins. What process is occurring in these cells?
Describe how external signals can influence the pathway of cell differentiation.
Describe how induced pluripotent stem cells (iPSCs) are created.
Describe the difference between totipotent, pluripotent, and multipotent stem cells.
Describe the process by which a zygote develops into a multicellular organism with specialized cells.

Which of the following best describes a stem cell? (1) A cell that can divide and become any type of cell (2) A cell that cannot divide (3) A cell that only forms muscle tissue (4) A cell that is already specialized
Which of the following best explains why muscle cells and nerve cells look and function differently? (1) They have different DNA (2) They express different sets of genes (3) They are exposed to different temperatures (4) They have different numbers of chromosomes
Which of the following is a key difference between embryonic stem cells and adult stem cells? (1) Only embryonic stem cells can differentiate (2) Adult stem cells are pluripotent, embryonic are multipotent (3) Embryonic stem cells can become any cell type, adult stem cells are more limited (4) Adult stem cells are found only in embryos

Fill in the blank: In animals, most cell differentiation occurs during ________ development.
Fill in the blank: In humans, the fertilized egg is also known as a ________.
Fill in the blank: In plants, regions where cells remain undifferentiated and continue to divide are called ________.
True or False: All cells in a multicellular organism have the same DNA.
True or False: All differentiated cells can revert to a stem cell state under normal conditions.
True or False: Differentiated cells can usually divide to produce more of the same type of cell.
True or False: Differentiation can be influenced by both internal and external factors.
