4. Row 1, Col 1 What are chromosomes made of? Chromosomes are made of strands of DNA.

5. 1,2 What is a gamete? (Give 2 examples for a bonus 50 each.) A gamete is a sex cell. Examples: egg and sperm.

6. 1,3 What is the name for the process where matter passes in and out of a cell? Osmosis.

7. 1,4 What is the name of the type of cell produced by meiosis. (Bonus 100: What usually is their purpose?) Haploid cells. They are usually reproductive cells.

8. 2,1 Describe the difference between positive and negative mutations. Positive mutations help the individual survive and reproduce. Negative mutations hinder the individual.

9. 2,2 Name an animal that reproduces asexually. (50 bonus for each extra animal.) Sponges, hydras and starfish can reproduce asexually.

10. 2,3 What is contained in the nucleus? Chromosomes.

11. 2,4 Which form of cell division is represented by this image? How do you know? (Bonus 100) Meiosis (2 divisions happen to result in 4 cells.)

12. 3,1 Name 3 things that your genes control. (100 each for a max of 500) Gender, Eye colour, hair colour, height, skin colour, facial structure

13. 3,2 What kind of reproduction is being shown by these pictures? External fertilization.

14. 3,3 What is an organelle? Give 2 examples of organelles that would be found in an animal cell. Organelles are parts of a cell that perform a specific function. Examples would be the nucleus, cell wall, cytoplast, cell membrane, vacuoles and chloroplast.

15. 3,4 What is the purpose of mitosis? To grow tissue and replace dead cells.

16. 4,1 What is a gene? A gene is a section of DNA which controls a characteristic.

17. 4,2 Name 4 organisms that reproduce by spores. (100 each) Algae, moss, ferns, puffballs, mushrooms.

18. 4,3 What is a chloroplast? (Bonus 100: What kind of cell has one?) A chloroplast is the part of a cell that performs photosynthesis. Only plant cells have chloroplasts.

19. 4,4 Suppose you start with one cell. If mitosis happens 3 times and then meiosis happens once, how many cells you have at the end? 32 (1 x 2 x 2 x 2 x 4 = 32.)

20. 5,1 Describe the process by which two parents with brown eyes can have a child with blue eyes. If both parents have a brown eye gene and a blue eye gene, then they will both have brown eyes since the blue eye gene is recessive. If they both pass on the blue eye gen to a child, the child will have blue eyes.

21. 5,2 What do the following things have in common? Wind, poop, insects and hummingbirds. They are methods of dispersal for pollen, seeds and spores.

22. 5,3 Point to the following in this diagram of a cell: 1. Nucleus 2. Cell membrane 3. Cytoplasm What kind of cell is this and how do you know? It is an animal cell because it has no chloroplast or cell wall. It is also round.

23. 5,4 Meiosis produces cells called haploid cells. Describe 2 key features of haploid cells. Haploid cells have only half the number of chromosomes (23 instead of 46.) Their chromosomes are a mix of features from the original 46.
