23. Cleavage furrow This is called a ______________ This cell is _____________ cell. an animal a plant an animalPlants don’t have cleavage furrows.

24. Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) INTERPHASE ________________ DNA is all spread out as chromatin and nuclear membrane is visible ________________ DNA scrunches up and chromosomes are first visible ________________ Made up of G1, S, G2 ________________ Chromosomes line up in middle of cell PROPHASE INTERPHASE METAPHASE

25. Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) INTERPHASE _______________ DNA is copied and cell prepares to divide _______________ Chromatid arms separate and move to opposite ends of the cell _______________ Chromosomes unwind into chromatin & nucleus returns _______________ Nuclear membrane & nucleolus disappear ANAPHASE TELOPHASE PROPHASE

26. Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I) TELOPHASE __________________ Two nuclei are visible __________________ First dividing phase ___________________ Centrosomes containing centrioles & spindle fibers appear next to nucleus __________________Cytoplasm is split between two cells _________________ Spindle fibers and centrioles disappear PROPHASE PROPHASE CYTOKINESIS TELOPHASE

27. _______ Cell makes a copy of its DNA _______ Division of chromosomes happens S M

28. C _______ Division of cytoplasm happens _______ Follows S and cell makes the molecules and organelles needed for cell division _______ Made up of telophase, anaphase, prophase, and metaphase G2 M

29. Phase of mitosis where the cytoplasm is split between two cells CYTOKINESIS Name the phases of the cell cycle in order starting with G1 G1 S G2 M C

30. Type of cell division used by organisms to grow bigger, repair injuries, and replace worn out cells. The center of a chromosome that holds the chromatid arms together mitosis centromere

31. chromatids 2 identical arms that make up a chromosome

32. Phase of mitosis in which two nuclei are visible, the nucleus returns, spindle fibers disappear, and DNA spreads out as chromatin telophase Shallow groove in an animal cellmembrane near the old metaphase plate during cytokinesis Cleavage furrow

33. Type of nuclear division that produces 2 diploid daughter cells that are genetically identical to the parent cell mitosis Type of division used by bacteria to reproduce Binary fission

34. Phase in which the cytoplasm issplit between the 2 daughter cells cytokinesis 1st phase of mitosis in which thenucleolus disappears and centrioles and spindle fibers appear. prophase

35. Disease in which body cells lose their ability to control cell division cancer Repeating sequence of events that cells go through during their lifetime Cell cycle

36. mitosis Phase in which the nucleus divides Phase in which cells grow and matureand where they spend most of their life G1

37. Area next to the nucleus in which the centrioles are found that organizes the formation of the spindle centrosomes Phase in which the nuclear membranedisappears and the spindle fibers attach to the kinetochores metaphase

38. Phase in which the chromosomesline up in the middle of the cell metaphase Phase after S in which cells make the molecules and organelles needed forcell division G2
