Continuity of cells Flashcards
(14 cards)
What are centrioles?
Centrioles are structures involved in cell division, helping organize the spindle fibers during mitosis.
What is cytokinesis?
Cytokinesis is the process of cytoplasm division, resulting in two daughter cells after mitosis.
What is mitosis?
Mitosis is the process of cell division that results in two genetically identical daughter cells.
What is the G1 phase in the cell cycle?
The G1 phase is the first phase of interphase where the cell grows and carries out normal functions.
What is the S phase in the cell cycle?
The S phase is the phase of interphase where DNA replication occurs.
The cell increases in size
What is the G2 phase in the cell cycle?
The G2 phase is the second growth phase where the cell prepares for mitosis.
What is the M phase in the cell cycle?
The M phase is the phase where mitosis and cytokinesis occur.
What is the purpose of the spindle fibers during mitosis?
Spindle fibers help separate chromatids and ensure proper chromosome distribution to daughter cells.
What happens during prophase?
During prophase, the chromatin condenses into chromosomes, the nuclear envelope breaks down, and spindle fibers form.
What happens during metaphase?
During metaphase, chromosomes align along the cell’s equatorial plate.
What happens during anaphase?
During anaphase, sister chromatids are pulled apart toward opposite poles of the cell.
What happens during telophase?
During telophase, nuclear envelopes re-form around the separated chromatids, which begin to de-condense
What is apoptosis?
Apoptosis is programmed cell death, which removes damaged or unnecessary cells.
