Building A Plant II: The Living Plant Cell Mitosis ­ Cells arise from other cells ­ 1 cell becomes 2 genetically identical daughter cells The Cell Cycle G1 Phase ­ Cells double in size and add mass ­ Organelles become more numerous G1 Checkpoint ­ Test to determine whether cell will go to function within the cell (specialized function) or continue to go through reproduction (mitosis) S Phase ­ DNA synthesis ­ Copies of each chromosome (x shaped chromosome) joined in the middle by centromeres ­ 2 of every chromosome G2 Phase ­ Sets up cell for mitosis ­ Structures for cell division begin to assemble ­ Chromosomes condense ­ Cycle continues Phases of Mitosis Interphase ­ Chromosomes are relaxed, become easily accessible strands to make MRNA (chromatin) ­ Nuclear membrane intact Early Prophase ­ Chromosomes condense to be evenly divided ­ Individual chromosomes made of 2 identical chromatids ­ Centrosomes begin to form at either end of the cell (structures made of microtubules to kinetochore center of each chromosome) ­ Nucleoli, nucleus, and nuclear membrane disintegrate Late Prophase ­ Microtubules extend from centrosome toward chromosomes Metaphase ­ Chromosomes line up on the central axis/middle of the cell ­ Microtubules connect to kinetochore Anaphase ­ “ana” in Greek means “apart” ­ Microtubules pull identic
