Phases (II)
Cancer
Reproduction
Random Wrap-Up
100
Homologous chromosomes separate during this phase of Meiosis.
What is anaphase I?
100
This is used to help plant cells divide their cytoplasm.
What is a cell plate?
100
Cancer cells are a problem because they won't stop doing this.
What is dividing?
100
Prokaryotes reproduce by this method.
What is binary fission?
100
These are three reasons a cell needs to go through mitosis.
What is growth, repair, and asexual reproduction?
200
Crossing over happens during this phase of Meiosis.
What is prophase I?
200
These are the two main events of prophase.
What is chromatin condenses into chromosomes and nucleus/nucleolus break down?
200
A mass of uncontrolled dividing cells is called this.
What is a tumor?
200
If an organism's diploid number is 50, they have this many chromosomes.
What is 25?
200
Any cell observed under the microscope is 90% likely to be in this phase.
What is interphase?
300
Duplicated chromosomes line up in the middle of the cell during this phase.
What is metaphase?
300
If the chromosomes fail to separate properly during anaphase, this is said to have happened.
What is nondisjunction?
300
Cancer cells that have spread through the blood stream are said to have done this.
What is metastasized?
300
Once an egg gets fertilized, it becomes known as this.
What is a zygote?
300
Mitosis produces 2 daughter cells that can be described as being these 3 things. (think about how they relate to the parent cell, how many chromosomes each cell has, and what kind of cells they are)
What are genetically identical, diploid, somatic cells?
400
Sister chromatids (centromeres) separate during these phases. (Must name BOTH phases)
What is anaphase of mitosis and anaphase II of meiosis?
400
If the S phase was eliminated from the cell cycle, what would happen to the daughter cell?
What is have half the amount of genetic info (chromosomes)?
400
Cancer cells that are only clumped in one area are described as being this.
What is benign?
400
The presence of this makes a person male instead of female.
What is the y chromosome?
400
Name the 3 pros and 2 cons of asexual reproduction.
What is produce many offspring, reproduce quickly, easy to reproduce for pros? What is no genetic diversity and unlikely to be able to adapt to extreme environmental conditions for cons?
500
DNA is copied during this phase.
What is S phase of interphase?
500
If cells were to go through several rounds of interphase and mitosis but did not go through cytokinesis, what would happen?
What is have large cells with many nuclei?
500
These are ways cancer can be treated. (You must name all 3)
What is surgery, radiation, chemotherapy?
500
Genetic variation is increased in sexually reproducing organisms by these 4 ways.
What is crossing over, independent assortment, random fertilization of egg by sperm, and mutations
500
These female gametes are small and cannot take place in reproduction because they gave up most of their cytoplasm to the other gamete.
What are polar bodies?
