2 The organelle that makes ribosome

3 Nucleolus

4 Three organelles that plant cells would have that animal cells wouldn’t

5 Cell Wall Central Vacuole Chloroplast

6 The “highway system” of the cell

7 Endoplasmic reticulum

8 Genetic material (DNA) is found in this organelle

9 Nucleus

10 Reason why cells must divide

11 Nutrient supply across the cell membrane can not keep up with nutrient demand of a larger cell

12 What does DNA stands for? And What shape does DNA take?

13 Deoxyribonucleic acid Double Helix

14 The three parts that make up DNA and the small segments of DNA are called what? ______________________

15 Sugar, Phosphate and Bases Gene

16 Provide names to 4 bases found in DNA and indicate their pairing partners.

17 A (adenine), T (Thymine), C (Cytocine), G (guanine) A with T; C with G Note : if one of your DNA strands has the following sequence…. ATTAAGCA What would be the complimentary strand?

18 Most of the time DNA exists in the nucleus in the form of what ? ___________________

19 Chromatin

20 How is the message for a protein (to be made) carried from the nucleus to the ribosome?

21 The DNA message for a specific protein is copied into RNA which leaves through nuclear pore and delivered message to the ribosome

22 The longest stage of the cell cycle?______________ What occurs during that phase? (provide 3 reasons)

23 Interphase: -growth and preparation -DNA replication continued growth and preparation (including copy organelles and making proteins)

24 Draw sister Chromatids. Make sure to label the centromere. What do the two sister chromatids have in common

25 Sister chromatids are replicated chromosomes. They are identical copies of DNA

26 Q1:What Phase of mitosis is occurring in the diagram below? Q2: Explain what is happening in the phase above.

27 The sister chromatids are being ripped apart at he centromere and move to the opposite sides of the cell

28 Q: If you started out with 365 chromosomes in the parent cell, how many chromosomes would each of the daughter cells have

29 365

30 Q:What occurs during metaphase?

31 Chromosomes line up across the middle of the cell

32 The process by which one cell divides into two new cells

33 Mitosis

34 Q:Which of the following is not a type of asexual reproduction? Spore formation, gamete formation, binary fission, budding, fragmentation, vegetative reproduction?

35 Gamete formation

36 Q: What type of asexual reproduction is occurring in the diagram found below?

37 Binary fission

38 Phase of cell division that is not really part of mitosis

39 Cytokinesis

40 Stage during which chromatids replicate to produce chromosomes

41 Interphase

42 Q: The sperm & egg are referred to as… Q: How many chromosomes will an egg or sperm cell have if the parent cell had 46 chromosomes? It is described as _____________ (haploid/ or deploid)

43 Gametes, 23 chromosomes, haploid

44 A pair of matching chromosomes are said to be …

45 Homologous

46 Q: What stage of meiosis is occurring in the picture found below? Q: Referring to the picture above, what has lined up along the equator? Q: What can occur during meiosis

47 Metaphase I, homologous chromosomes, crossing over

48 Why meiosis is required for sexual reproduction

49 Haploid gametes combine to form a normal diploid zygote.

50 What is the difference between Anaphase I and Anaphase II?

51 Anaphase I: homologous chromosome pairs are pulled away from each other towards opposite ends of the cell Anaphase II: sister chromatids are split apart at the centromere and move to the opposite pole.

52 Q:What are two advantages of asexual reproduction? What is the major advantage of sexual reproduction?

53 Asexual Reproduction: 1. Genetically identical offspring 2. lots of offspring can be reproduced quickly Sexual Reproduction: Genetic diversity
