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 8
A scientist observes a group of cells under a microscope. Some cells have long extensions, while others are round and flat. What process has likely occurred?
A student claims that all cells in a plant leaf are identical. Is this correct? Explain your answer.
Describe one example of a specialized cell and its function.
Describe the difference between a stem cell and a specialized cell.

A researcher observes that when a certain gene is mutated, blood cells fail to develop properly in an animal. What does this suggest about the role of genes in cell differentiation?
A scientist is studying two groups of cells from the same organism. Group A cells can develop into any cell type, while Group B cells can only become muscle or nerve cells. What is the main difference between Group A and Group B 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 makes skin (4) A cell that only makes blood
Which of the following best explains why nerve cells are long and thin? (1) To store energy (2) To carry signals over long distances (3) To divide quickly (4) To absorb nutrients
Which of the following is a reason why cell differentiation is important for healing wounds? (1) It creates new stem cells (2) It allows specialized cells to replace damaged ones (3) It stops cell division (4) It removes all cells from the area
Which of the following is a result of cell differentiation? (1) All cells look the same (2) Cells perform different jobs (3) Cells stop dividing (4) Cells lose their DNA
