Vocabulary
Definition of mitosis?
The process of cell division in which a single cell divides to produce two genetically identical daughter cells. It occurs in somatic (non-reproductive) cells and is essential for growth, repair, and replacement of cells.
What is prophase?
This phase marks the beginning of mitosis, where chromosomes condense, and the spindle apparatus forms.
What are somatic cells?
Mitosis takes place in these types of cells, responsible for growth and repair.
What is asexual reproduction?
Mitosis is responsible for this type of reproduction in single-celled organisms.
Definition of Chromatid?
One of two identical copies of a chromosome connected by a centromere, formed during DNA replication.
What is metaphase?
In this phase, chromosomes align on the equatorial aircraft of the cellular.
What is mitosis?
This process ensures that each daughter cell has the same number of chromosomes as the parent cell.
What happens when mitosis goes out of control?
Uncontrolled mitosis can lead to cancer and the formation of tumors.
Definition of diploid?
A cell with two complete sets of chromosomes, one from each parent, which is the chromosome number maintained during mitosis.
What is anaphase?
Sister chromatids are pulled apart to opposite poles during this phase.
What is cytokinesis?
The division of the cytoplasm after mitosis is called this.
What part of the cell is divided during mitosis?
The nucleus.
Definition of centrioles?
Cylindrical organelles in animal cells that help organize the spindle fibers during mitosis.
What is telophase?
During this phase, two new nuclear envelopes form around separated chromosomes.
What is meiosis?
Unlike mitosis, this type of cell division produces gametes with half the chromosome number.
What kind of cells are made by mitosis?
New cells that are exactly like the old ones.
Definition of Anaphase?
The third phase of mitosis, where sister chromatids are separated and pulled to opposite poles of the cell by spindle fibers.
What is prophase, metaphase, anaphase, telophase?
The sequence of phases in mitosis always occurs in this specific order.
How Mitosis is important?
Mitosis enables growth, repair, and replacement of cells while maintaining genetic consistency.
Why do your skin cells divide so often?
To replace old or damaged skin.
