Reproduction
Cell Division
100
What happens in the S phase of the cell cycle?
S stands for synthesis therefore the DNA is replicated.,
100
During which phase of the cell cycle does mitosis happen?
M-phase
100
What role do centrioles play in mitosis?
connect to the spindle fibers
100
What is the major advantage of sexual reproduction over asexual reproduction?
it provides genetic diversity
100
What happens to the volume of a cell as its surface area increases?
the volume increases faster than the surface area.
200
What is the advantage of bundling a cell's DNA into separate chromosomes?
Each daughter cell will get the same number of genes.
200
What event occurs during interphase?
centrioles duplicate
200
What is the role of spindle fibers?
to help separate the chromosomes.
200
What type of reproduction is binary fission?
asexual
200
The rate at which wastes are produced by cell partially depends on ___________________.
volume
300
When during the cell cycle are chromosomes visible?
only during cell division
300
What phase includes cytokinesis?
telophase
300
What are the phases of mitosis?
Prophase, metaphase, anaphase, and telophase
300
Why do normal cells grown in a petri dish tend to stop growing once they have covered the bottom of the dish?
Because contact with other cells stops the cell growth
300
What problems do larger cells have over smaller ones?
Moving materials in and out of a larger cell is more of a problem than with smaller cells because of the volume
400
When during the cell cycle is a cell's DNA replicated?
during the S-phase (synthesis)
400
What is the first phase of mitosis?
Prophase
400
During which phase of mitosis do the chromosomes line up on the equatorial plate?
metaphase
400
What is the difference between cell division in a plant cell and an animal cell?
the plant cell has a cell plate
400
What results from cell division?
daughter cells
500
What type of cell would form a cell plate during cytokinesis?
only plants have cell plates
500
When chromosomes are duplicated and joined by a centromere, what are they called?
chromatid
500
What are the two main stages of cell division called?
mitosis and cytokinesis
500
What protein helps regulate the cell cycle?
cyclin
