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 11

Describe one example of cell differentiation in animals.
Describe the difference between embryonic stem cells and adult stem cells.
Describe the role of transcription factors in cell differentiation.
Explain how gene expression leads to cell differentiation.
