Tiny structures located in the cytoplasm of animal cells near the nuclear envelope
What are centrioles?
100
Before cell division occurs, the cell replicates, or copies, all of its DNA.
What happens before S, synthesis, stage?
100
G1, S, and G2.
Name the main events of the interphase
.
100
disorder in which some of the body's own cells lose the ability to control growth
What is cancer?
100
Part of eukaryotic cell division during which the cell nucleus divides
What is mitosis?
200
Process by which a cell divides into two new daughter cells.
What is cell division?
200
T
H
200
Prophase
What is the chromosomes become visible?
200
first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
What is prophase?
300
One of two identical “sister” parts of a duplicated chromosome
What is chromatid?
300
Each daughter cell has an increased ratio of surface area to volume.
As a cell increases in size, which increases more rapidly, its surface area or its volume?
300
The “in-between” period of growth in the cell cycle
What is interphase?
300
Telophase.
What is chromosomes begin to disperse into a tangle of dense material and nuclear membrane starts to reform?
300
Second phase of mitosis, during which the chromosomes line up across the center of the cell
What is metaphase?
400
Area where the chromatids of a chromosome are attached
What is the centromere?
400
1. The problem of information storage because each daughter cell gets one complete set of genetic information. 2. The problem of increasing size by reducing cell volume.
Two of the reasons why cells divide.
400
Made up of DNA,which carries the cell's coded genetic information.
What are chromosomes made of?
400
Formed during telophase of plant cells.
What is a cell plate?
400
The third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
What is anaphase?
500
Fanlike microtubule structure that helps separate the chromosomes during mitosis
What is a spindle?
500
A growing cell divides forming two “daughter” cells.
What happens before a cell becomes too large?
500
Cells come from preexhisting cells.
What is a part of the cell theory?
500
Anaphase
What is the chromosome pairs separate and move toward opposite poles?
500
Fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material
