What is the 1st phase of mitosis?
prophase
100
Which two phases do not belong in mitosis? A) interphase and prophase. B) cytokinesis and metaphase. C) anaphase and telophase. D) interphase and cytokinesis
D) interphase and cytokinesis
100
Which structure organizes the movement of spindles? A) nuclear membrane. B) spindle fibers. C) prophase. D) centrioles
D) centrioles
100
This phase produces two identical cells.
cytokinesis
100
A human skin cell has 46 chromosomes. It goes through the cell cycle to produce two new skin cells. How many chromosomes does each new skin cell have?
46 chromosomes
200
The cell spends 90% of its time in which phase?
interphase
200
Cytoplasm (the fluid inside the cell) divides immediately after this period. A) interphase. B) metaphase. C) mitosis. D) G2
C) mitosis
200
The centromere holds what structures together?
chromatids or sister chromatids
200
Which specific phase shows the cell in the process of tearing apart into two cells?
telophase
200
Cells that are damaged and grow uncontrollably are called ___________________
cancer or cancer cells
300
The term for cell death is ______________.
apoptosis
300
DNA is copied in which part of interphase?
S (synthesis) phase
300
This structure is first seen in prophase and starts to disappear in telophase.
spindle fibers
300
Which phase would you see the chromosomes lined up in the middle of the cell?
metaphase
300
You must answer both questions: 1) How many cells are produced at the end of the cell cycle? 2) Are they genetically different or genetically identical?
1) two cells are made at the end of the cell cycle. 2) both cells are genetically identical

Name the phases of mitosis in order.
prophase, metaphase, anaphase, and telophase
400
Name all the phases of the cell cycle in order
Interphase, prophase, metaphase, anaphase, telophase, and cytokinesis
400
What structure starts to break down in prophase but reappears in telophase?
nuclear membrane/envelope
400
Which phase shows copies of organelles like mitochondria and ribosomes being made?
interphase
400
What is the first thing that the cell needs to do when it finds errors during interphase?
It tries to fix the error.
500
You must answer both questions to receive credit. You many increase the time limit to 1 minute. What type of cells in the human body does mitosis divide? Give three examples of these type of cells.
It divides all body cells in the human body. You can list any type of body cell (like red blood cells, skin cells, hair cells, heart muscle cells, etc.) except for sperm or egg.
500
What structure is formed in plant cells but not animal cells during cytokinesis?
cell plate
500
Why does a plant cell need a cell plate when it goes through cytokinesis?
Plant cells form a cell plate to divide the cells since they have a cell wall and a fragile cell membrane.
500
Which phase would see the chromosomes thicken and become visible under a microscope?
prophase
500
Name the 3 parts of interphase in order.
G1, S, and G2
