What is mitosis?
Mitosis is the process of cell division that results in two identical daughter cells.
Phases of mitosis
1. Prophase 2. Metaphase 3. Anaphase 4. Telophase
True or false: Mitosis occurs in prokaryotic cells.
False, because prokaryotic cells divide by binary fission, not mitosis.
What happens during prophase?
Chromatin condenses into chromosomes, and the nuclear envelope starts breaking down.
Difference between anaphase and telophase
Anaphase: sister chromatids separate. Telophase: nuclear envelopes re-form around each set.
Fill in the blank: In metaphase, chromosomes align at the _____.
equatorial plane or metaphase plate.
What is the role of spindle fibers?
Spindle fibers help separate the chromosomes during mitosis.
True or false: Cytokinesis occurs during telophase.
True, because cytokinesis is the division of the cytoplasm after mitosis.
Describe cytokinesis in animal cells.
The cell membrane pinches inward, forming two separate daughter cells.
Compare mitosis and meiosis.
Mitosis produces 2 diploid cells; meiosis produces 4 haploid cells.
What is chromatin?
Chromatin is the material consisting of DNA and proteins that make up chromosomes.
Which phase follows metaphase?
Anaphase follows metaphase.
Fill in the blank: During prophase, the ____ begins to dissolve.
nuclear envelope.
What forms during telophase?
Nuclear membranes re-form around the separated sets of chromosomes.
True or false: Mitosis has a resting phase.
False, because mitosis is a continuous process without a resting phase.
What happens to DNA during mitosis?
DNA is replicated before mitosis, ensuring each daughter cell gets a complete set.
