Mitosis Flashcards
(26 cards)
What is mitosis?
Mitosis is the process of cell division that results in two genetically identical daughter cells.
How many stages are there in mitosis?
There are four main stages in mitosis: prophase, metaphase, anaphase, and telophase.
What happens during prophase?
During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.
True or False: The chromosomes align at the center of the cell during metaphase.
True.
Fill in the blank: The stage of mitosis where sister chromatids are pulled apart is called _______.
anaphase.
What is the role of spindle fibers in mitosis?
Spindle fibers help to separate the chromosomes and pull them to opposite sides of the cell.
What occurs during telophase?
During telophase, the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell begins to split.
Which stage of mitosis is characterized by the formation of the metaphase plate?
Metaphase.
What are sister chromatids?
Sister chromatids are identical copies of a chromosome that are connected by a centromere.
True or False: Mitosis results in four daughter cells.
False.
What is the significance of mitosis in multicellular organisms?
Mitosis is essential for growth, development, and tissue repair in multicellular organisms.
What happens to the nuclear envelope during prophase?
The nuclear envelope breaks down during prophase.
Multiple Choice: Which phase comes after metaphase? A) Telophase B) Anaphase C) Prophase
B) Anaphase.
What structure forms during prophase to help separate chromosomes?
The mitotic spindle.
Fill in the blank: In _______ phase, the chromosomes are aligned in the middle of the cell.
metaphase.
What is the outcome of mitosis?
The outcome of mitosis is two genetically identical daughter cells.
True or False: Cytokinesis occurs during mitosis.
False; cytokinesis is a separate process that occurs after mitosis.
What is the function of the centromere?
The centromere is the region of a chromosome where sister chromatids are joined together.
During which phase do chromatids become individual chromosomes?
Anaphase.
What happens to the chromosome number during mitosis?
The chromosome number remains the same in the daughter cells as it was in the parent cell.
Multiple Choice: Which of the following is NOT a stage of mitosis? A) Prophase B) Interphase C) Telophase
B) Interphase.
What marks the start of telophase?
The arrival of the separated chromosomes at opposite poles of the cell marks the start of telophase.
Fill in the blank: The _______ is responsible for organizing the microtubules during mitosis.
centrosome.
What is the primary purpose of mitosis?
The primary purpose of mitosis is to ensure equal distribution of genetic material to daughter cells.
