CELL CYCLE: GROWTH AND DIVISION
INTERPHASE: Prepatory stage for cell division. Three things happen: 1.
The cell increases in size (grows)
2. Organelles duplicate within the cell
3. Chromotin condense to chromosomes.
Centrioles are copied in cytoplasm.
MITOSIS: Second stage for cell duplication. The duplication
distributed into two cells by seperation of chromosomes.
*creation of two nuclei
PHASE 1: PROPHASE
*Centrioles appear with fibers
*nuclear membrane breaks down
coil to chromotids with centrioles
2: METAPHASE * centrioles at opposite ends of the cell
*fibers connect to centromere of the chromatids
line up in the center (row)
3: ANAPHASE * centromeres split
*chromatids go to opposite sides of the cell (2 daughter chromosomes)
PHASE 4: TELOPHASE * new nuclear membrane
forms around two sets of chromosomes
Cell membrane starts to pinch inward to create two seperate cells.
The cytoplasm divides, the organells go to each new cell. This
process begins at the same time as telophase. The final stage
of the cell cycle.
pinch in at membrane
cells-cell plate formed in the middle and grows outwards.
BINARY FISSION: Prokaryotic
cells only have one chromosome. Asexual.
