The Basics of Mitosis
What is the purpose of mitosis in multicellular organisms?
To grow, repair tissues, and replace dead or damaged cells.
What is the first phase of mitosis?
Phases of Mitosis
What structure pulls chromatids apart during mitosis?
Spindle fibers
Does mitosis result in genetically identical or diverse cells?
Genetically identical cells
Which phase of mitosis is the longest?
Prophase
How many daughter cells are produced in mitosis?
Two daughter cells
During which phase do chromosomes line up in the middle of the cell?
Prophase
What are the identical copies of a chromosome called, which are connected at a centromere?
Sister chromatids
How many divisions occur in mitosis?
One division
What phase does the cell spend most of its life in, before entering mitosis?
Interphase
Mitosis is a part of what larger cell cycle process?
The cell cycle
In what phase do sister chromatids separate and move to opposite poles?
Anaphase
What organelle organizes spindle fibers during mitosis in animal cells?
Centrosome
What type of cells does mitosis produce, somatic or gametes?
Somatic cells
True or False: Cytokinesis is a part of mitosis.
False
What type of cells (eukaryotic or prokaryotic) undergo mitosis?
Eukaryotic cells
What is the final phase of mitosis before cytokinesis begins?
Telophase
What is the name of the structure where chromosomes attach to spindle fibers?
The kinetochore
In mitosis, do homologous chromosomes pair up as they do in meiosis
No, homologous chromosomes do not pair up in mitosis.
What kind of reproduction relies on mitosis?
Asexual reproduction.
Name the three main reasons mitosis is important
Growth, tissue repair, and asexual reproduction
Name all four phases of mitosis in the correct order
Prophase, metaphase, anaphase, telophase
What dissolves to allow chromosomes to move during prometaphase?
The nuclear envelope
Which process (mitosis or meiosis) is involved in growth and repair?
Mitosis
How does mitosis in plant cells differ from mitosis in animal cells?
Plant cells form a cell plate during cytokinesis, while animal cells form cleavage
