Reproduction
#1: A type of reproduction where the offspring created carry genetic information from a only one parent
Asexual
#21: What is the correct order of the diagrams?
D --> A --> C --> B
#13: When during the cell cycle are chromosomes visible?
Prophase
#8: Which letter(s) represent cell division (mitosis)?
D
#22: Cancer is a disorder in which some cells have lost the ability to control __________ _________________.
cell division / timing / growth
#1: This type of reproduction leads to genetic variation in offspring
Sexual Reproduction
#3: What would happen if the DNA was not copied but the cell divided anyway?
The resulting daughter cells would contain half the amount of DNA that they're supposed to.
#4: What are the phases of the cell cycle (in the correct order)?
Interphase (G1 --> S --> G2) --> Prophase --> Metaphase --> Anaphase --> Telophase --> Cytokinesis
#10: During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
Metaphase
Density dependent inhibition means that cells stop dividing once they sense other cells surrounding them.
Do healthy cells exhibit this characteristic?
Do cancer cells exhibit this characteristic?
Healthy - Yes! :)
Cancerous - No :(
#1: This type of reproduction results in a group of organisms that is more likely to survive disease/infection
Sexual Reproduction
#7: Which letter(s) in the diagram represent(s) interphase?
A, B, C
#19: What is cytokinesis?
The division of the cytoplasm
#11: During which phase of mitosis are the sister chromatids pulled apart to opposite poles of the cell?
#18: What’s unique about stem cells, compared to other cell types?
Stem cells have the potential to develop into any cell type
#2: Why are we made up of many small cells, as opposed to just a few large cells?
Larger cells have a more difficult time moving materials in and out. A larger cell places a heavy burden on the DNA.
#20: What are the structures labeled X and Y?
X - Centrioles
Y - Spindle fibers
#14: Describe how centrioles are used in mitosis. What do they responsible for?
Organizing the spindle fibers to do their job of pulling apart sister chromatids.
#12: During which phase of mitosis does the nuclear membrane disappear and spindle fibers first appear?
Prophase
#17: What is cell specialization? (differentiation)
When a cell gets its job (ex: a stem cell develops into a skin cell)
#9: Label the chromosome diagram A and B
A - Centromere
B - Sister chromatid
#5: What happens in each phase?
G1:
S:
G2:
M
G1: cell growth
S: DNA replication
G2: final preparations for mitosis
M: Mitosis (cell division)
#16: How is the division of plant cells and animal cells different? Include a specific structure.
Plant cells contain a cell wall and therefore, cannot pinch in like animal cells. Plant cells form a cell plate first.
#15: During normal cell division, a parent cell having 9 chromosomes will produce two daughter cells, each containing how many chromosomes?
9 chromosomes
#23: How can stem cells be used to help people who have become sick with cancer?
Stem cells can be used to grow tissues, which can develop into organs, etc.
