QR Challenge: Cell Growth & Reproduction Quiz

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

Questions / Answers (teacher reference)

Question	Answer
1. What type of reproduction (sexual or asexual) results in offspring that are genetically identical to the parent	asexual
2. What type of asexual reproduction do bacteria perform	binary fission
3. Cells go through a period of stages where they grow and reproduce called	cell cycle
4. The protein that controls the cell cycle is called	cyclin
5. DNA forms this structure as cells go through division (hint: it's shaped like an X)	chromosome
6. The center section of a chromosome is called	centromere
7. Process where the cell's DNA is copied then the nucleus divides is called	mitosis
8. Phase of mitosis where the nuclear membrane breaks down, spindle fibers form, and chromosomes appear	prophase
9. Phase of mitosis where the chromosomes are lined up in the middle of the cell	metaphase
10. Phase of mitosis where the chromosomes are split into sister chromatids	anaphase
11. Phase of mitosis where the nuclear membrane reforms, chromatids condense, and a cleavage furrow forms	telophase
12. Cell cycle stage that occurs after mitosis when the cell's cytoplasm splits in two	cytokinesis
13. Condition that can occur when cells keep replicating and growing uncontrolled	cancer
14. Meiosis produces sex cells called __________and___________	sperm and egg
15. How many cells are produced at the end of meiosis	4
16. Cells that contain 2 sets of chromosomes are called	diploid
17. Cells that contain 1 set of chromosomes are called	haploid
18. True or False: Meiosis produces haploid cells	true
19. What are two ways that meiosis produces cells that are genetically different from each other	crossing over, random line up, segregation
20. Pairs of chromosomes that have the same size, same shape, and carry the genes for the same traits	homologous chromosomes
21. Process where a sperm cell enters an egg cell	fertilization
22. Process where different genes are turned on or off to determine what a cell's function will be	differentiation
