Cell Cycle & Regulation
Mitosis & Cytokinesis
Asexual Reproduction
Multicellular Life
100
One long piece of DNA; there are 46 in every cell of the body.
Chromosome
100
During what stages of the cell cycle are cells performing their normal functions?
Gap1 & Gap2
100
How many steps are there to mitosis? What are they?
4; Prophase, metaphase, anaphase, telophase
100
Give 3 examples of organisms that reproduce asexually.
Options: sea stars, flatworms, strawberries, potatoes, euglena, anemones, yeast, protists, ameobas, etc.
100
What does it mean when a cell becomes "differentiated"?
It becomes specialized with specific functions
200
This divides the nucleus and the DNA inside of it.
Mitosis
200
This type of tumor is harmless.
Benign tumor
200
The cell spends most of its time in this phase.
Interphase
200
What is a disadvantage of asexual reproduction?
Low amounts of genetic diversity mean that they are incapable of adapting to changing environments.
200
What is the organization of cells in living organisms?
cells, tissues, organs, systems
300
Body cells that can develop are undifferentiated and can turn into any different types of cells.
Stem cells
300
Why is it such a problem when cells start to metastasize?
At that point, cells have broken away from the original tumor and have spread to other parts of the body?
300
Why does the DNA coil up at the beginning of mitosis?
To keep it organized during the process.
300
What is one advantage of asexual reproduction?
It can quickly result in large numbers of offspring.
300
What are the two ways that stem cells can be harvested?
Through adult stem cells and embryonic stem cells
400
A type of asexual reproduction in which a single-celled organism divides into 2 parts.
Binary Fission
400
What do each of the following letters mean as it pertains to the cell cycle: G1 S G2 M?
Gap 1, Synthesis, Gap 2, Mitosis
400
What happens during metaphase?
The chromosomes are lined up in the middle of the cell.
400
What other 2 other types of asexual reproduction?
binary fission, regeneration, budding, sporing, fragmentation
400
What kinds of diseases can stem cells cure?
diabetes, cancer, and heart damage
500
This is programmed cell death.
apoptosis
500
Why don't all cells divide at the same rate?
Some cells are not used as often as others and they may need to divide faster or slower depending on the age of the organism.
500
What is the difference between mitosis and cytokinesis?
Mitosis separates the nucleus and the membranes. Cytokinesis separates the cytoplasm.
500
Why can't multi-cellular organisms reproduce asexually?
Multi-cellular organisms have many different types of cells that perform different functions at different rates. Therefore, they are incapable of reproducing asexually.
500
Why is stem cell unique?
It is undifferentiated and can, therefore, become almost any type of specialized cell
