- Which of the following plant types has the
gametophyte as its prominent generation?
A. Angiosperms
B. Bryophytes
C. Conifers
D. Gymnosperms
E. Ferns - During which phase of the cell cycle does cross-
ing over occur?
A. Metaphase of mitosis
B. Metaphase I of meiosis
C. Prophase I of meiosis
D. Prophase of mitosis
E. Anaphase I of meiosis
For questions 3–6, please use the following answer
choices:
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
E. Cytokinesis
- During this phase, the split sister chromatids,
now considered to be chromosomes, are moved
to the opposite poles of the cell. - During this phase the nucleus deteriorates, and
the mitotic spindle begins to form. - During this phase, the two daughter cells are
actually split apart. - During this phase, the sister chromatids line up
along the equator of the cell, preparing to split. - Which of the following organisms is diploid (2n)
only as a zygote and is haploid for every other
part of its life cycle?
A. Humans
B. Bryophytes
C. Fungi
D. Bacteria
E. Angiosperms
8. Which of the following statements is true about
a human meiotic cell after it has completed
meiosis I?
A. It is diploid (2n).
B. It is haploid (n).
C. It has divided into four daughter cells.
D. It proceeds directly to meiosis II without an
intervening intermission.
9. Which of the following is nottrue about cyclin-
dependent kinase (CDK)?
A. It is present only during the M phase of the
cell cycle.
B. When enough of it is combined with cyclin,
the MPF (mitosis promoting factor) formed
initiates mitosis.
C. It is a protein that controls other proteins
using phosphate groups.
D. It is present at all times during the cell cycle.
10.Which of the following statements about meio-
sis and/or mitosis is incorrect?
A. Mitosis results in two diploid daughter cells.
B. Meiosis in humans occurs only in gonad cells.
C. Homologous chromosomes line up along
the metaphase plate during mitosis.
D. Crossover occurs during prophase I of meiosis.
E. Meiosis consists of one replication phase fol-
lowed by two division phases.
