Review for Unit Test  Catalyst  What are two similarities between photosynthesis and cellular respiration?  What are two differences between mitosis and meiosis? Write in complete sentences! Don’t talk during the Catalyst!

Objectives By the end of today, SWBAT…  MASTER the four cellular processes!  Kick Ms. Stroh’s butt tomorrow!

Review  Our first topic is… Photosynthesis and cellular respiration!!!

Photosynthesis and Cellular Respiration  6CO 2 + 6H 2 O + sunlight  C 6 H 12 O 6 + 6O 2  C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + ATP

Photosynthesis Cellular Respiration Glucose + Oxygen Water + Carbon Dioxide Energy (ATP) 6CO 2 + 6H 2 O + sunlight  C 6 H 12 O 6 + 6O 2 C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + ATP

Quiz, Quiz, Trade!  You have 15 minutes to quiz as many partners as possible  Answer each other’s review questions  Guide the other person to the answer  Trade questions  Hands up, clap up!  Find a new partner  QQT questions just might be on the test tomorrow…  If you don’t participate, it’s your bad…

Review  Our second topic is… Phases of mitosis and meiosis!!!

Cell Phases  Interphase  Prophase  Metaphase  Anaphase  Telophase

Cell Phases – Mitosis  Interphase:Time in between cell divisions. At end of interphase, chromosomes double.  Prophase:Sister chromatids (the duplicated chromosomes) attach to one another.  Metaphase:Sister chromatids line up in the center of cell (called the metaphase plate) Time in between cell divisions.  Telophase:  Anaphase:Spindles pull sister chromatids apart, to opposite ends of the cell. Cleavage furrow forms, “pinching” cell in half  Interphase:

Cell Phases – Meiosis  Meiosis has two parts  Meiosis 1: genetic information switched, cells divide  Meiosis 2: cells divide ONE MORE TIME

Choices  Your classwork grade today is based on you completing one of the following:  1) A foldable of mitosis/meiosis/differences  2) A poem/rap song about the phases of mitosis  3) 8 possible test questions that you will present to the class

Review  Our third topic is… Products of mitosis and meiosis!!!

Mitosis  Mitosis goes through PMAT one time.  Therefore, it produces two cells.  Each of these cells is exactly the same.  Since all somatic cells are 2N, and the cells produced by mitosis are exactly the same as the original cell, the cells produced by mitosis are 2N.

Meiosis  Meiosis goes through PMAT two times.  Therefore, it produces four cells.  Each of these cells is different.  Each gamete is different because in meiosis 1 some genetic information gets switched between chromosomes. This is why you do not look exactly like your relatives.  Each gamete has half as much DNA as the original germ cell. So, each cell is only 1N.

Review Packet  If you completed half of the review packet last night…  Good work! You get an answer key!  Check your answers, and ask me questions.  If you did not complete half of the review packet last night…  You can work on it now, and ask me questions.  No answer key, sorry. Do your work next time.

Exit Question  Name 3 differences between mitosis and meiosis.  How are the products and reactants related in CR and Photosynthesis? Write in complete sentences! Don’t talk during the Catalyst!
