Cell Reproduction Prokaryotes Bacteria Eukaryotes Plants & animals

Eukaryotes Contain a nucleus & membrane bound organelles Asexually reproduce cells by mitosis

Cell Cycle Stages in growth & division Interphase: M Phase (Mitosis) G1 Phase S Phase G2 Phase M Phase (Mitosis) Cytokinesis

Interphase

Interphase: G1 PHASE S PHASE G2 PHASE First growth stage Cell increases in size Cell prepares to copy its DNA DNA replication Chromosomes duplicate Cell continues to grow

M Phase (MITOSIS) (nuclear division) Phases: Prophase Metaphase Anaphase Telophase

Cells Undergoing Mitosis

Prophase DNA becomes visible as chromosomes Nuclear membrane disappears Spindle begins to form

Human Chromosomes (image is a Karyotype)

Steps in Metaphase Spindle fibers attach to each chromosome M = middle Spindle fibers attach to each chromosome Cell aligns its chromosomes in the middle of the cell

Metaphase

Anaphase A= Apart Cell chromosomes are separated

Anaphase

Telophase Separation of chromosomes completed Nucleus reform 2 nucleus and 1 cytoplasm

Telophase

Cytokinesis Forms two, identical daughter cells After Mitosis (division of nucleus) Forms two, identical daughter cells
