What is the purpose of mitosis?
To produce haploid cells
To create genetic diversity within a population
To produce two identical daughter cells with the same number of chromosomes as the parent cell.
To repair damaged DNA
List the phases of mitosis in order.
prophase, metaphase, anaphase, telophase, prometaphase
metaphase, prophase, anaphase, telophase, prometaphase
prophase, prometaphase, metaphase, anaphase, telophase
interphase, prophase, metaphase, anaphase, telophase
What happens during prophase?
Chromatin condenses into chromosomes, nuclear membrane breaks down, nucleolus disappears, spindle fibers form.
Chromatin disperses into cytoplasm
Nuclear membrane thickens
Nucleolus enlarges
During which phase of mitosis do the chromosomes line up at the center of the cell?
Anaphase
Prophase
Telophase
Metaphase
What is the significance of metaphase in mitosis?
Metaphase ensures equal distribution of chromosomes to daughter cells.
Metaphase is skipped in the cell cycle.
Metaphase is when DNA replication occurs.
Metaphase marks the end of mitosis.
Describe the process of anaphase in mitosis.
Anaphase involves the condensation of chromosomes
Anaphase is the phase where DNA replication occurs
Anaphase in mitosis involves the separation of sister chromatids towards opposite poles of the cell.
Anaphase results in the formation of a cell plate
What occurs during telophase?
Absence of cytokinesis
Reformation of nuclear membrane, decondensation of chromosomes, disassembly of spindle fibers, and cytokinesis
Formation of new chromosomes
Assembly of spindle fibers
Explain the difference between cytokinesis in plant and animal cells.
In plant cells, cytokinesis involves the formation of a cleavage furrow, while in animal cells, cytokinesis occurs through the formation of a cell plate.
Cytokinesis in plant cells involves the formation of a cleavage furrow.
Both plant and animal cells form a cell plate during cytokinesis.
In plant cells, cytokinesis involves the formation of a cell plate, while in animal cells, cytokinesis occurs through the formation of a cleavage furrow.
How does mitosis contribute to growth and repair in multicellular organisms?
Mitosis contributes to growth by reducing the size of cells in an organism
Mitosis contributes to growth by increasing the number of cells in an organism and to repair by replacing damaged or dead cells with new ones.
Mitosis contributes to growth by decreasing the number of cells in an organism
Mitosis contributes to repair by causing mutations in existing cells
What would happen if mitosis was not properly regulated in the body?
Increased energy levels
Properly functioning immune system
Enhanced cell repair mechanisms
Uncontrolled cell division leading to tumor formation or cancer.
