Ch 3, 6 Cell Growth and Reproduction

Question 1

interphase

Answer 1

period from cell formation to cell division
nuclear envelope called chromatin
four sub phases:
G1(gap 1) major growth and metabolism
G0- gap phase 
S-DNA replication
G2-prepae for division

Question 2

cell division

Answer 2

process necessary for growth and tissue repair 2 main events:
1. division of the nuclear material
mitosis occur in somatic cells-daughter cells are diploid, does not occur in most mature cells of nervous tissue, skeletal muscle, and cardiac muscle
Meiosis-occurs only in germ cells and results in haploid gametes
2. cytokinesis; the process of diving the cytoplasm
