Differentiation, Growth & Cell-Cycle Control — Drills · Grade 10 Science
Chapter: Cell Division, Reproduction & DevelopmentWhat these drills covers
By the end of Differentiation, Growth & Cell-Cycle Control you should be able to:
- I can explain how similar genomes can support different cell functions.
- I can connect regulated cell division and differentiation with growth and repair.
2 questions, written answer, each with a worked explanation.
Vocabulary used: differentiation, gene expression, checkpoint.
Problem 1
Name two kinds of evidence needed to study cell specialization.
Answer and explanation
Compare gene/protein expression and cell structure or function, ideally through development and under controlled conditions.
Problem 2
Explain why “all cells have the same DNA, so all cells must do the same job” fails.
Answer and explanation
Expression and regulatory conditions differ; DNA presence alone does not mean every gene is used in the same way.
