The Cell Cycle and Mitosis
The ____ _____ is the complete life cycle of a cell. cell cycle The ____ _____ is the complete life cycle of a cell. Parts of the cell cycle include: G1 = 1st growth phase S = synthesis G2 = 2nd growth phase M = mitosis interphase
Two types of cell reproduction include: mitosis meiosis
Sex cells are reproduced during... meiosis OR mitosis Regular body cells reproduce through... meiosis OR mitosis
How many body cells are produced during mitosis? two How many sex cells are produced during meiosis? 4 sperm - OR - 1 egg and 3 polar bodies
Somatic cells are reproduced through... The prefix soma- = “body” Somatic cells are reproduced through... meiosis OR mitosis
Examples of somatic cells include: skin membranes organs ANYTHING BUT SPERM OR EGGS!
The cell cycle for somatic cells includes: interphase and mitosis.
The steps of mitosis are... prophase metaphase anaphase telophase
How do I remember the steps of the cell cycle and mitosis? I.P.M.A.T.
The longest stage of the cell cycle is _________. interphase Interphase is often called the “resting” phase, but is the cell doing nothing? NO!!!!
During interphase... the DNA replicates the cell grows the cell works
Interphase
The first step of mitosis is... prophase. What happens during prophase? chromatin coils into chromosomes nuclear envelope disappears spindle fibers form
Prophase
What happens during metaphase? The next phase is… metaphase. What happens during metaphase? chromasomes line up at the equator
Metaphase
The next step of mitosis is... anaphase. What happens during anaphase? Chromosomes are pulled apart by spindle fibers
Anaphase
The final step of mitosis is... telophase. What happens during telophase? cytokinesis cleavage into 2 cells nuclear membranes reform
Telophase
What do you call the 2 new cells produced during mitosis? daughter cells
Which is a full set: haploid or diploid? Do mitotic daughter cells have haploid or diploid number of chromosomes? diploid Which is a full set: haploid or diploid? diploid
