1 3 CELL REPRODUCTION INB ACTIVITIES
2 Eukaryotic & Prokaryotic Cell Division Teacher Notes/Answer Key Eukaryotic and Prokaryotic Cell Division Eukaryote: - Complex process - Involves many chromosomes and crossing over - Can be asexual or sexual (offspring are unique to parents) - Undergo mitosis: DNA/organelle replication during Interphase, Prophase, Metaphase, Anaphase, Telophase, & cytokinesis. - Uses meiosis to make sex cells, egg and sperm Both: -part of the life cycle of virtually all cells -Occurs when new cells are needed -DNA is replicated -one cell (the parent cell) divides to form two new cells (daughter cells) -Can be asexual Prokaryote: - Simple process - Involves one chromosome. - Asexual reproduction: Offspring are identical to parent cell - Undergo binary fission: DNA replication, chromosome segregation, cell separation. - Or conjugation: the transfer of genetic material (the plasmid) via direct contact or a bridge like connection. Directions: Cut out and glue the diagrams into your notebook. Cut along the three vertical lines to split the picture in thirds. Fold the tabs back along the dashed line Underneath the flaps, describe the similarities and differences between eukaryotic and prokaryotic celldivision.

4 Mitosis Card Sort Teacher Notes/Key Directions: Create enough copies of the card sort to use in small groups or as individuals. Print on cardstock, cut and laminate if you plan on using them year after year with groups. If not, have students cut out the cards on the following pages and the card sort pocket. Fold the pocket along the dashed lines and glue into notebook to hold the cards. Arrange the picture and description cards appropriately to show the process of cell division through mitosis. Some stages of mitosis may have more than one picture card. If necessary, remove some of the cards representing prophase and metaphase to avoid confusion and have one card per phase. Use the card sort as a warm-up activity as you walk them through the processes or use as test prep as students RACE to get their equations in order! This card sort activitycomes intwo sizes use the larger size with groups, smaller size for individualsor partners.
5 Mitosis Card Sort Teacher Notes/Key
6 Mitosis Card Sort Teacher Notes/Key Interphase: Cell s resting phase. Cell spends 90% of its time in this phase. Cell copies/doubles its chromosomes and prepares for cell division (mitosis) Prophase: Mitosis begins during prophase. Nucleolus and Nuclear membrane disappear. Centrioles (or poles) appear and move to opposite ends of cell. Spindle fibers begin to stretch across the cell (like spider webs). Chromosome pairs or sister chromatids become visible (attached to one another by a centromere) Metaphase: Chromosome pairs line up at the equator (center of the cell). Spindle fibers attach to the chromosomes at the centromere. THINK: Meet in the middle Anaphase: Chromosome pairs (sister chromatids) separate and move to opposite ends of the cell Telophase: Two new nuclei form. Chromosomes change to chromatin (threads rather than rods). Mitosis ends Cytokinesis: Cytoplasm separates and two new cells are formed. Different in plants (cell wall forms down the center) and animals (cell membrane pinches in).
