During the Cell Cycle, a cell grows, prepares for division, and divides to form two daughter cells, each of which begins the cycle again. Anaphase Cell Division Mitosis M phase M Interphase is S phase replication DNA the period of growth that occurs between cell Interphase dividison G2 phase Interphase is divided into three phases: G1, S, & G2 G1 Phase S Phase G2 Phase The G1 phase is a period of The S phase replicates During the G2 phase, many of activity in which cells do most chromosomes and synthesizes the organelles and molecules of their growing. Cells will DNA molecules. When DNA required for cell division are increase in size and synthesize replication is completed, the cell produced. When G2 is new proteins and organelles. enters the G2 phase. completed, the cell is ready to enter the cell is ready to enter the M phase. Mitosis are divided into four phases: prophase, metaphase, anaphase, & telophase Below are cells in two different phases of the cell cycle, fill in the blanks using the word bank: Chromatin Nuclear Envelope Chromosome Sister Chromatids Nucleolus Spinder Fiber Centrosome Centrioles Centrioles 5 Chromosome 1 v 6 Sister chromatids 2 Chromatin 7 Spindle fiber 3 Nucleolus 8 Centrosome 4 Nuclear envelope v The Cell Cycle & Mitosis Microscope Lab: Interphase, Mitosis, & Cytokinesis Directions: Look under the microscope slides and draw what you see Interphase Interphase is divided into Prophase - Chromatin three phases: G1, condenses into S, & G2 chromosomes Interphase is the in - Centrioles seperate between stages of cell - A spindle forms division. - The nuclear envelope breaks down Metaphase - The chromosomes Anaphase - The sister line up across the chromatids separate center of the cell into individual - Each chromosome chromosomes and is connected to a are moved apart. spindle fiber at its centromere. Telophase - The chromosomes Cytokinesis - The cytoplasm gather at oppostie pinches in half. ends of the cell & - Each daughter cell lose their distinct has an identical set shapes. of duplicate - Two new nuclear chromosomes. envelopes will form..
