Science Meiosis,Mitosis, cell cycle
Terms in this set (17)
fall+winter The majority of a cell's life. Growth, organelle production, DNA Replication, starting point, loosely packaged DNA
spring The part of the cell cycle where the Nucleus divides. Genetic material condensed into chromosomes and separated
summer Cell Membrane and Cell wall pinch off forming two new identical cells
cells membranes pinch off
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
What are the phases of mitosis in order?
Genetic material condenses, Two Chromatids joined by a centromere
Chromosomes line up in the middle of the cell. Centrioles attach spindle fibers to chromosomes
Chromosomes are ripped apart, pulled to opposite sides of the cell. Each side ends up with a complete set of Chromosomes.
telo - far, New nuclear membrane forms, cell starts separating
Based on the following pie graph, Interphase is by far the longest.
Stages of the cell cycle lab. Which stage of the cell life cycle is the longest? Is it much longer?
Cells such as sperm or egg, contain half the normal number of chromosomes for an organism. Haploid.
Sex Cells / Gametes
A pair of Chromosomes that serve similar functions, one from mom, one from dad, Use an image of "human Chromosomes"
23 pairs, 46 total chromosomes
Humans have how many pairs and chromosomes
For any Organism, sex cells have half the number of chromosomes for a body cell for that organism
Why do sex cells have half?
Cells with only half of the normal amount of chromosomes
Cell with a pair of every chromosome
Normal human cells have 46 chromosomes. If a Mom and Dad each contributed a full 46 to their child, the child would have too many chromosomes!
Why is Meiosis needed?
Stages of Meiosis
Interphase, Prophase I, Metaphase I, Anaphase I, teleophase I, cytokinesis, Prophase II, Metaphase II, Anaphase II, Telophase II, cytokinesis
