1. Why don’t cells just keep growing bigger and bigger? Nutrients need to diffuse in and that would be too slow with a large cell 2. When during the cell cycle is a cell's DNA replicated? S Phase

3. The structure labeled A in Figure 10-2 is called the Centromere 4. The structures labeled B in Figure 10-2 are called Sister Chromaids 5. During which phase(s) of mitosis are structures like the one shown in Figure 10-2 visible? Prophase 6. The first phase of mitosis is called Prophase 7. During which phase of mitosis do the chromosomes line up along the middle of the dividing cell? Metaphase 8. What are the phases of mitosis in their proper sequence? Prophase – Metaphase – Anaphase - Telophase 9. What is the role of the spindle during mitosis? Separate homologous chromosomes and sister chromatids 10. One difference between cell division in plant cells and in animal cells is that during cytokenesis plant cells have A cell plate 11. During normal mitotic cell division (mitosis), a parent cell having four chromosomes will produce two daughter cells, each containing 4 chromosomes 12. True/False - Homologous chromosomes may have one chromosome for hair color and another for eye color. False – they contain the same genes 13. If an organism’s diploid number is 12, its haploid number is 6

14. Gametes have how many chromosomes compared to body cells? 1/2 15. Gametes are produced by the process of meiosis 16. Chromosomes form tetrads during Prophase I 17. Unlike mitosis, meiosis results in the formation of Gametes (haploid cells) USING SCIENCE SKILLS Figure 11-6

18. Which letter represents the phase where tetrads line up at the equator of the cell in figure 11-6? B 19. Which of the following stages in Figure 11-6 are 2N? A, B C 20. Which phase in figure 11-6 is Metaphase II? F 21. Organisms that cannot make their own food and must obtain energy from the foods they eat are called Autotrophs 22. The Calvin cycle is another name for Light Independant reactions

23. Cellular respiration releases energy by breaking down glucose 24. Which of these processes takes place in the cytoplasm of a cell? glycolysis 25. Which organelle makes proteins using coded instructions that come from the nucleus? ribosomes 26. List and describe the main events of the cell cycle. Illustrate your description with a diagram of the cell cycle. Interphase – Mitosis (PMAT) - cytokinesis

27. Which cells have to divide through meiosis and explain why? Gametes so that they can become haploid

28. When you look at a group of cells under a microscope most cells appear to be in interphase. Explain why. Because interphase is the longest phase

29. When does crossing over happen in meiosis? Why is it important for this to occur? Prophase I – it makes all gametes unique
