Cell Division Review

Multiple Choice

If a plant cell has 18 chromosomes, how many chromosomes are found in each cell at the end of mitosis?

• 9

• 18

• 36

• varies

Multiple Choice

Mitosis is essential to life because it

• creates gametes for sexual reproduction

• maintains genetic continuity and chromosome number

• controls cell functions

• provides energy for the cells

Multiple Choice

Which statement is true about the M phase or MITOTIC (mitosis) cell division?

• Each daughter cell produced has only 1/4th the number of chromosomes of the parent cell

• Each daughter cell produced has only 1/2 the number of chromosomes as the parent cell

• Each daughter cell produced has the same number of chromosomes as the parent cell

• Each daughter cell produced has twice the number of chromosomes as the parent cell.

Multiple Choice

Which is the correct order of cell mitosis?

• 1, 2, 3, 4

• 2, 3, 1, 4

• 3, 2, 1, 4

• 4, 2, 3, 1

Multiple Choice

Which phase of mitosis is represented in the diagram?

• prophase

• anaphase

• metaphase

• telophase

Multiple Choice

Which of the following best describes cancer?

• absence of cyclins in the DNA

• multiple gene mutations on a chromosome in DNA

• the presence of genetic defects caused by hereditary disorders

• uncontrolled cell growth caused by mutations in genes that control the cell cycle

Multiple Choice

During meiosis I, what happens?

• crossing over in prophase I

• independent assortment in metaphase I

• homologous chromosomes line up at the equator

• all of the choices are correct

Multiple Choice

During meiosis, one _____ cell divides and makes _____ sex cells.

• haploid/diploid

• diploid/haploid

• homologous/heterozygous

• heterozygous/homologous

Multiple Choice

If a cell has 12 chromosomes at the beginning of meiosis, how many will it have at the end of meiosis?

• 24

• 12

• 6

• 3

Multiple Choice

Which is true concerning meiosis?

• Meiosis produces sex cells that join to form offspring during sexual reproduction

• Meiosis halves the number of chromatids

• Meiosis begins with a haploid cell and ends with four diploid cells

• Meiosis doubles the number of chromatids

Multiple Choice

Which of the following best describes how the process of crossing over during meiosis leads to an increase in

genetic diversity?

• During prophase I, DNA replication takes place, and homologous chromosomes trade places with each other

  before lining up in preparation for metaphase.

• During prophase I, DNA segments are exchanges between homologous chromosomes, resulting indifferent

  combinations of alleles.

• During prophase II, fragments of DNA break off of chromosomes and attach to the ends of other

  chromosomes, resulting in different gene sequence.

• During prophase II, sister chromatids separate from each other, and as they travel to opposite ends of the

  cell, DNA segments of nearby chromosomes are exchanged.

Multiple Choice

Mitosis and meiosis are both processes involved in cell division. Which statement correctly compares mitosis and meiosis?

• Mitosis and meiosis both produces genetic variation

• Mitosis results in the production of two genetically identical diploid cells and meiosis produces four non-identical haploid cells

• Mitosis and meiosis are both divided into only 4 distinct phasesprophase, metaphase, anaphase and interphase

• Mitosis results in the production of two genetically identical diploid cells and meiosis produces four genetically dentical haploid cells
