The second stage of mitosis during which kinetochore microtubules align sister chromatids along the equator of the cell.
What is metaphase?
100
The middle waist section at which two chromatids are joined together to form a chromosome
What is centromere?
100
the type of reproduction creating identical offspring of a single parent, without the participation of sperm and egg
What is asexual reproduction?
100
True or False: a cell plate is in an animal cell
What is false.
100
An abnormally growing mass of body cells
What is tumor?
200
The first stage of mitosis, during which visibly dark, condensed chromosomes are found in the nuclear envelope.
What is prophase?
200
An ordered sequence of events that extends from the time a cell is first formed from a dividing parent cell until its own division into two cells
What is cell cycle?
200
The structures within a nucleus that contain most of the organism's DNA
What is chromosome?
200
A cleavage furrow creates two daughter cells of what type of cell: animal or plant?
What is animal?
200
This type of tumor remains at its original site and does not cause illness.
What is benign?
300
The fourth stage of mitosis before cytokinesis, the nuclear envelope re-forms around separated sister chromatids and kinetochore microtubules disappear.
What is telophase
300
An imaginary line found half way between the two mitotic spindle poles on which chromosomes align during metaphase.
What is metaphase plate?
300
In this type of reproduction cells genetically resemble their parents more closely than they resemble unrelated individuals of the same species, but they are not identical to their parents or each other
What is sexual reproduction
300
This cell does not change size or shape during cellular division: plant or animal?
What is plant cell.
300
This type of tumor can spread into neighboring tissues and other parts of the body, displacing normal tissue and interrupting organ function as it goes.
What is malignant tumor?
400
The third stage of mitosis. In this stage the sister chromatids separate into individual chromosomes and are pulled apart.
What is anaphase?
400
A complex of microtubules that form between opposite poles of a cell during mitosis. Serve to separate and move sister chromatids to opposite ends of the cell for division.
What is spindle fibers?
400
Process that results in reproduction of a cell
What is cell division?
400
The indentation of the cell's surface that begins the progression of cleavage, by which animal cells undergo cytokinesis
What is cleavage furrow?
400
Cancers of blood-forming tissues, such as bone marrow, spleen, and lymph nodes
What is leukemia and lymphomas?
500
The process that follows the last stage of mitosis. With two complete copies of the DNA now in two different regions of one cell, the cell membrane will pinch and divide the cytoplasm in half. The result is two individual cells that are identical to the original cell.
What is cytokinesis?
500
a protein secreted by certain body cells that stimulate other cells to divide
What is growth factor?
500
The sequence of events: prophase, metaphase, anaphase, telophase, cytokinesis.
What is mitosis
500
This grows outward, accumulating more cell wall materials as more vesicles fuse with it
What is cell plate?
500
Cancers that originate in the external or internal coverings of the body, such as the skin or the lining of the intestines
