Mitosis and Meiosis

occurs before mitosis begins INTERPHASE occurs before mitosis begins Chromosomes are copied CELL MEMBRANE NUCLEUS CYTOPLASM CHROMOSOMES

Interphase Plant Cell Animal Cell

Prophase Nuclear Membrane disappears DNA becomes X CENTRIOLES SISTER CHROMATIDS SPINDLE FIBERS

Prophase Plant Cell Animal Cell Spindle fibers Centrioles

Metaphase Chromosomes line up in the center SPINDLE FIBERS

Metaphase Plant Cell Animal Cell

Anaphase Chromosomes separate SPINDLE FIBERS

Telophase Nuclear membrane appears Two new nuclei form.

Cytokinesis occurs after mitosis Cells break apart 2 daughter cells are created (exact copies of the original cell)

MITOSIS CREATES 2 IDENTICAL CELLS WITH A FULL SET OF DNA

Animal Mitosis -- Review Interphase                                                              Prophase                                                              Metaphase                                                              Anaphase                                                              Telophase                                                             

MEIOSIS…back of 70

The process by which sex cells are made Creates 4 cells with half the number of chromosomes

Mitosis Meiosis Makes 2 cells makes 4 cells Full DNA ½ the DNA Body cells sex cells (egg, sperm)

(Formal Quiz) Tuesday Photosynthesis vs. cellular respiration Using the microscope Plant cells/animal cells Cell membrane structure Osmosis and diffusion Cell theory Prokaryotic/eukaryotic Organelles- what the parts do/ look like on a diagram Mitosis vs meiosis If you have missed class, and have not gotten the make up notes, I will meet you in front of the school Tuesday at 8:00am to get your notebook caught up.
