Mitosis and Meiosis

Foldable Today we will create a foldable on Mitosis & Meiosis. First fold 2 pieces of paper in half. Use the title on the front page: Mitosis & Meiosis Foldable

Foldable Open the foldable to the 1 st page and write the following titles on pages 1 & 2: Mitosis (pg.1)Meiosis (pg. 2)

Pages 1 & 2 You will draw and label each circle with the number of chromosomes shown in the circles below.

Pages 3 & 4 Open foldable to the next 2 pages (3 & 4) and write the definition for Mitosis and Meiosis on the correct sides. (Leave space for definitions & comparisons!) Mitosis (pg.3) Definition: Meiosis (pg. 4) Definition:

Mitosis The process by which a nucleus divides into 2 identical “daughter” cells, each containing the same number & type of chromosomes as the parent cell.

Meiosis The division of a parent cell twice to create four different daughter cells. They have half the number of chromosomes as the parent.

Mitosis One division Same number of Chromosomes Identical to Parent genetically 2 daughter cell produced Body Cells Meiosis Two divisions Half number of chromosomes Different from parent genetically 4 daughter cells produced Sex cells (Gametes)

Pages 5 & 6 Phases of Mitosis (pg.5) Draw the phases: Prophase Metaphase Anaphase Telophase Phases of Meiosis (pg. 6) Draw the phases: Meiosis I: Prophase I Metaphase I Anaphase I Telophase I Meiosis II: Prophase II Metaphase II Anaphase II Telophase II

Binary Fission (watch video after you finish, link is on the last slide) On back of foldable include this information: The simple cell division in which one cell splits into two Allows for rapid reproduction Used by bacteria
