The Cell Cycle, Growth And Asexual Reproduction Flashcards
Function of the cell cycle and mitosis
Growth
Asexual reproduction
The cell cycle
The sequence of event that occurs from the formation of an individual cell until that cell divides to form daightercells
Interphase in detail
G1-rapid growth
S(synthesis) - DNA doubles, histone protein doubles
G2-chromosome condenses, mitochondria and centrioles doubles
Nuclear division
To produce 2 daughter cells from one parent cell
Genetically identica
Name 5 stages of mitosis
Prophase Metaphase Anaphase Telophase Cytokinesis
Prophase
Nucleoli disappears
Nuclear envelope disappears
Centrioles migrate to opposite sides
Spindle forma
Metaphase
Chromosome line up in the MIDDLE of the spindle arranged at 90degrees= METAPHASE PLATE
Joined to spindle fibres at the centromere
Anaphase
Centromere splits in 2
Spindle fibres contract pulling that chromatids apart
Telophase
Nuclear envelope reforms
Nucleoli reforms
Chromosomes decondense and become in-district
Cytokinesis
Cell organelles become evenly distributed around each nucleus
Cell divides into 2 daughter cells
Animals- cell cleavage
Plants- cell plate
