1 Anticipation GuideObserve the pictures on the next slide and in front of you…..Put the pictures in the correct order….or the order you think they should goWrite a short explanation for each step of the process
4 WARM-UPIt takes Cell A 1 hour to complete its cell cycle and produce two cells. The cell cycle of cell B takes 2 hours. How many more cells would be formed from Cell A than from Cell B in 6 hours?
5 The Life of a CellCell Cycle - the life cycle of a cell and how a cell livesThe cycle begins when the cell is formed and ends when the cell divides.Must make a copy of its DNA (DEOXYRIBONUCLEIC ACID)DNA is organized into structures called chromosomesEach new cell will be an exact copy of the parent cell
6 Prokaryotic Cells Binary Fission-”splitting into two parts” Results in two cells that each contain cell stuff one copy of the circle of DNA
7 Eukaryotic CellsMore complex organisms do not necessarily have more chromosomesHow many chromosomes do human cells have?Homologous chromosomes-pairs that are made up of similar chromosomes
8 The Three StagesStage one-interphase-the cell grows and copies its organelles and chromosomesChromatids-two copies of the duplicated chromosomesHeld together in the centomeretaggart.glg.msu.edu/bs110/mitosis.htm
9 Stage Two Mitosis-the process when the chromatids separate Ensures each new cell receives a copy of each chromosomeDivided into four phases
10 ProphaseNuclear membrane dissolves. Chromosomes condense into rod-like structures
11 MetaphaseThe chromosomes line up along the equator of the cell. Homologous chromosomes pair up.
12 AnaphaseThe chromotids separate and move to opposite sides of the cell
13 TelophaseThe nuclear membrane forms around each set of chromosomes, and the chromosomes unwind. Mitosis is complete
14 Cytokinesis The division of cytoplasm is called cytokinesis Plants reproduce differentlyA Cell Plate-forms in the middle of the cellContains the materials for the new membrane and cell wall
16 Reproductive CellsMeiosis-used to produce the cells animals use for sexual reproductionOrganisms produce specialized sex cells called Gametes or sex cellsGametes contain only half the number of chromosomes found in an organism’s body cellsTwo types of gametes (Sperm cells, male; Egg cells, female)Diploid Number-total number of chromosomes presentHaploid Number-number of chromosomes present in a gamete
17 More Meiosis The Process Meiosis I-Four stages Prophase I, Metaphase I, Anaphase I, Telophase IMeiosis II-similar to mitosisChromosomes do not replicate before they begin meiosis IICells Alive
