Chapter 10 Biology
Microtubules
A network of fibers to which the chromosomes are attached. They push and pull the chromosomes around the cell.
Eukaryotic Cells
All of the information that a cell needs to function is stored in the ________ of the cell.
Telophase
During what stage (of mitosis) does cytokinesis occur?
Interphase
G1, S, and, G2 are collectively known as what phase of the cell cycle?
Anaphase
In what stage (of mitosis) are the chromatids pulled to the opposite sides of the cell by the microtubules?
Telophase
In what stage (of mitosis) do the cells begin to pinch in to divide the cytoplasm?
Prophase
In what stage (of mitosis) do the centrioles begin to move to opposite poles, organizing the microtubules as they go along?
Telophase
In what stage (of mitosis) does the nuclear membrane return?
Centromeres
Sister chromatids are connected at an area called the _______.
Cell Cycle
The ________ is the life of the cell from the time that is formed from a dividing parent cell, until its own division into two cells.
G2
The cell assembles the special structures needed for cell division during the ________ phase.
G1
The cell increases its size, and manufactures extra enzymes and organelles during the ____ phase.
True
The chromosomes are replicated during prophase. True or False
Prophase
The chromosomes condense thicken, and become distinct from one another. The chromosomes are now visible in this stage (of mitosis).
Cytokinesis
The division of the cytoplasm is called _________.
Mitosis
The division of the nucleus is called _______.
True
The majority of the life of a cell is spent doing cell division. True or False
Cell Division
The pairs of sister chromatids are lined up at the center of the cell during ________.
G1, S, and G2
What are the three stages of the cell cycle that lead up to cell division?
DNA replication
What happens during the "S" phase?
Chromatids
What is the name for each duplicate half of a chromosome?
Daughter Cells
What is the name given to the two new cells that are formed at the end of cell division?
The purpose of mitosis is to produce two daughter cells that that are exact duplicates of the mother cell.
What is the purpose of mitosis?
They must be duplicated
What must happen to all chromosomes before cell division?
So, this way, they can carry out the same function as the mother cell.
Why is the duplication of the daughter cells in mitosis important?
Cell Division
_________ is the process by which cellular material is divided between two new daughter cells.
