Cell Division %26 The Cell Cycle

Answer the following multiple choice and true/false questions. Be warned - sometimes there is more than one right answer so you might need to check more than one box!

1. ___________ is the last step in the cell cycle.
reproduction of an organism is when one original organism makes an unique copy of itself., reproduction of an eukaryotic organism by combining genetic material from two different individuals of the same sex., reproduction of an organism by combining genetic material from two different individuals of different sexes. generate answer keys , reproduction of an organism is when one original organism makes an identical copy of itself.,
2. Each daughter cell has its own nucleus.
Circular DNA is replicated., As new material is added, the cell membrane pushes inward., The dividing organism is split into 2 identical cells. , All of the above,
3. Mitosis: An important step in cell division in which a new nucleus is created; occurs right before cell division. Mitosis only takes place in somatic cells.
TRUE, FALSE, ,
4. ____________ cells are body cells, or every cell in your body except egg cells or sperm cells (examples: heart cell, liver cell, bone cell, skin cell, etc.). They undergo mitosis.
making more cells within an individual., sexual reproduction to create offspring., the same thing as sexual reproduction in a eukaryotic cell., None of the above,
5. Mitosis is the process in which
TRUE, FALSE, ,
6. During the first growth phase (G1) in Interphase...
TRUE, FALSEweb page, ,
7. In eukaryotes, cells have very specifically timed steps of the cell cycle.
repair, replace, reproduce, and die, run, jump, leap, and spin, reproduce, replace, and fight disease., repair, replace, reproduce, and growth,
8. Asexual reproduction is the
TRUE, FALSE, online education ,
9. What are the three types of cell division?
a cancer cell., too big., infected with bacteria., too small.,
10. What are the steps required in binary fission?
ribosome., nucleus., endoplasmic reticulum., cell membrane.,
11. The _______________ is a center of a chromosome. It also serves as the point at which sister chromatids attach.
meiosis., cell cycles., cell membrane., mitosis.,
12. Cancer is a result of a haywire cell cycle. Cells have very specific instructions as to when to divide, and when to grow. These instructions are controlled by genes. If the genes are mutated in some way, they will not work properly and cell division may become out of control, leading to cancer.
TRUE, FALSE, ,
13. __________ or sex cells (sperm or egg) undergo meiosis.
cellular; prokaryotic, eukaryotic; genetic, cellular; genetic, prokaryotic; genetic,
14. Cell division is the
TRUE, FALSE, ,
15. Which statement(s) best describe haploid cells?
DNA must be replicated (copied) so that each cell gets a copy of DNA., New organelles and proteins must be created so that each cell is equipped for survival. , Bacteria must be created so that each cell is equipped for survival. , RNA must be replicated (copied) so that each cell gets a copy of DNA.,
16. Cells are capable of growing, reproducing, and programming cell death. Therefore, they have their own life spans, called
TRUE, FALSE, ,
17. The steps in the cell cycle that follow Interphase are :
mRNA, DNA, tRna, DNA and RNA,
18. As cells grow, their volume increases much faster than their surface area (cell membrane).
chromatid, sister chormosome, centromere, nucleus,
19. A cell will grow until it reaches a certain point, and then divide into two cells. This happens when the cell becomes
TRUE, FALSE, ,
20. During the synthesis phase (S) in Interphase...
G1, S, G2, None of the above,
21. Interphase is the shortest part of the cell cycle.
Metaphase, Telophase, Anaphase, Prophase,
22. The following steps are included in Interphase :
Interphase, Telophase, Prophases, Cytokinesis,
23. Chromosomes are made up of
TRUE, FALSE, ,
24. Purpose of Cell Division in Eukaryotes:
The cell is carrying out routine functions and making new proteins and organelles., DNA is replicated (copied) in preparation for cell division., The nucleus is well-defined and surrounded by the nuclear envelope. , The cell prepares for cell division by forming microtubules. ,
25. Meiosis: a process that occurs in gametes in which the number of chromosomes is cut in half.
The cell is carrying out routine functions and making new proteins and organelles., DNA is replicated (copied) in preparation for cell division., The nucleus is well-defined and surrounded by the nuclear envelope. , The cell prepares for cell division by forming microtubules. ,
26. Because bacteria are single-celled organisms, reproduction and cell division are the same thing in prokaryotes.
The cell is carrying out routine functions and making new proteins and organelles., DNA is replicated (copied) in preparation for cell division. school , The nucleus is well-defined and surrounded by the nuclear envelope. , The cell prepares for cell division by forming microtubules. ,
27. In humans, the diploid number is 46 (23 from mom, 23 from dad).
one nucleus is formed and shared by two cell., the creation of egg and sperm cells are formed., two nuclei are formed, each with an identical set of chromosomes. , two identical mother cells are formed.,
