2. 17L OQC Do Now: Multiplying by Dividing 9/8/11 1. A human body cell has 46 chromosomes. If your big toe is made of 1million cells, how many chromosomes are in your big toe? 3. If a young plant gone began as one cell and has gone through mitosis 10 different times, how many cells does it have? 2. A red blood cell has a cell cycle that lasts for 120 days. How many hours does it live? Most of its life is spent in which phase? (interphase, mitosis, or cytokinesis)

3. 17L OQC 2. The cell lives for 2, 880 hours and is in interphase for most of its life. (120 days x 24 hours = 2880 hours) Do Now ANSWERS 9/8/11 1. 1 million cells x 46 chromosomes each cell 46 million chromosomes (in the big toe!) 3. 1 original cell (1 st mitosis)  2 cells (2 nd mitosis)  4 cells (3 rd mitosis)  8 cells (4 th mitosis)  16 cells (5 th mitosis)  32 cells (6 th mitosis)  64 cells (7 th mitosis)  128 cells (8 th mitosis)  256 cells (9 th mitosis)  512 cells (10 th mitosis)  1,024 cells
