Cell Growth Review

Cell Growth, Mitosis

QuestionAnswer
division of the nucleus ; P-M-A-T mitosis
reproduction that leads to genetically identical cells asexual reproduction
reproduction that leads to genetically different cells sexual reproduction
means 2 copies of chromosomes diploid
means 1 copy of chromosomes haploid
aka body cells somatic cells
aka reproductive cells (egg and sperm) sex cells
diploid number in humans 46
haploid number in humans 23
self-programmed cell death apoptosis
90-95% of cell cycle ; G1, S, G2 Interphase

chromosomes condense and look like "X"s prophase
chromosomes line up in the center of cell metaphase
chromosomes split and chromatids move to opposite sides of cell anaphase
cell has 2 nuclei but has not split yet (cleavage furrow or cell plate visible) telophase
levels of biological organization cells --> tissues --> organs --> organ systems --> organism
all cells come from other cells, living things have at least 1 cell, cell are basic unit of life cell theory
this holds 2 sister chromatids together in the center centromere
