Has _______ phases. (How many?)
8
What happens during Anaphase?
The sister chromatids separate, becomes individual chromosomes, and move toward opposite poles of the cell.
What happens during Telophase I?
The separated chromosomes arrive at opposite poles, and the cell divides.
What happens during Prophase II?
The chromosomes condense, the nuclear envelope breaks down, and spindle fibers form.
Why is mitosis important to living organisms?
It ensures that the organism can grow and repair itself.
True or False: Meiosis is a form of cell division that produces reproductive cells.
True
What happens during Metaphase?
The chromosomes align along the metaphase plate.
What happens during Anaphase I?
The chromosomes are pulled to opposite poles of the cell.
What happens during Telophase II?
The chromatids reach the poles and nuclear envelopes reform around each set of chromosomes.
What happens during Mitosis Interphase?
The cell grows, performs its normal metabolic functions, and prepares for cell division.
Why is meiosis important to a living organism?
It ensures the species continues on through sexual reproduction.
What happens during Telophase?
The chromosomes begin to decondense, and the nuclear envelope reforms around each set of chromosomes making two separate nuclei.
What happens during Prophase I?
Chromosomes condense and pair up and DNA is exchanged between non-sister chromatids.
What happens during Metaphase II?
The chromosomes align along the metaphase plate in both cells.
In which phase does the cell spend most of its time?
Interphase
True or False: After Meiosis I and II are complete, a new organisms is created that is genetically EXACTLY like the parent organism.
False
What happens during Prophase?
Chromatin condenses into visible chromosomes.
What happens during Metaphase I?
Pairs of chromosomes align along the metaphase plate.
What happens during Anaphase II?
The sister chromatids are pulled apart and move to opposite poles of the cells.
