1. What does cell division produce?
Two identical cells.
2. Is cell division important for growth?
Yes
3. What is a unicellular organism?
One that is one cell
4. What is a multicellular organism?
One that has many cells
5. Are all of the cells in a multicellular organism the same?
No
6. How can one cell become a multicellular organism?
Cells must divide and change into different types of cells
7. What is the Cell cycle?
Period of growth, development, and division in the cells
of organisms
8. What are the two main phases of the cell cycle?
Interphase and Mitosis
9. Why is the cell cycle important?
It is reproduction in some organisms, growth in
multicellular organisms, and provides replacement of
worn out or damaged cells.
10. Why are Cycles in nature important?
because organisms get injured and parts must be
replaced and the older organisms must be replaced as
they die
11. What can affect the cycles in nature?
Weather or the seasons
12. What are pairs of identical chromosomes called?
sister chromatids
13. What structure connects the pair of sister chromatids?
Centromere
14. What is cytokinesis?
The dividing of the cytoplasm at the end of mitosis.
15. what is formed at the end of cytokinesis?
Two identical daughter cells
16. What happens to the nucleus during cell division?
The genetic material is duplicated and then divided to
form two new nuclei.
17. What are the cylindrical structures that aid in mitosis?
Centrioles
18. What are the thin fiber that connect to the centromeres
Spindle fibers
and pull the chromatids toward the opposite poles?
19. What are the cell structures that are chains of DNA
Chromosomes
containing the genetic material?
20. Where do cells come from?
From pre-existing cells
21. Which is longer, mitosis or Interphase?
Imterphase
22. Why is it important for the two new cells to be
It is important that the new cells are identical to the old
identical to the old cells?
cells, so the organism can function correctly.
Study these questions – they come the notes and stuff that we have covered since the last test.
Also remember to study the phases of mitosis from the quizlet or study cards that we made last Thursday. The test will
be divided 13 questions from the phases and 17 from the questions above.
Study hard and good luck.
