specialized reproductive cell | gamete |
male gamete | sperm |
process in which a male gamete joins a female gamete to produce a new cell that develops into an organism | fertilization |
stage in the cells cycle during which the nucleus divides | mitosis |
reproduction in which one parent produces offspring that is identical to the parent | asexual reproduction |
female gamete | egg |
phase of the cell cycle in which the cell grows and makes a copy of its chromosomes | interphase |

stage of the cell cycle in which a new cell wall or membrane divides the cell | cytokinesis |
characteristics of living things | genetic traits |
structures in nucleus that store DNA | chromosomes |
