Document Summary
A. 3. a) cells do not spontaneously arise (a. 3. a. 1) they can"t just randomly create themselves. B. 2. b) however some still divide doesn"t apply to all cells. Primarily seen in nerve cells and red blood cells. No need because already got to job or adulthood . However, most cells divide at some point: cell division. C. 3. a) reproduces the entire organism (c. 3. a. 1) new organism is the result of division. 2 functions for division (c. 4. a. 1) growth and development (c. 4. a. 2) renewal and repair (c. 4. a. 2. a) after fully grown (c. 4. a. 2. b) when necessary. C. 4. b) cell division continues even after complete growth (c. 4. b. 1) ex: cut on skin new skin cells repair/renew damaged skin cells. All parts of cell divided into new cells. 1 main function of cell division (c. 5. c. 1) distribute genetic material into daughter cells: genetic material. Eukaryotes (d. 1. c. 1) usually > 1 linear dna molecule (d. 1. c. 1. a) in nucleus (d. 1. c. 1. b) organized into chromosomes: chromosomes. Dna (e. 2. a. 1) double helix (e. 2. a. 1. a) wrapped around proteins (e. 2. a. 1. a. i) histone proteins (dna + protein) (e. 2. a. 1. a. i. a)
