    Metaphase - nuclear membrane fully breaks down, spindle fibres attach to the centromere and the chromosomes line up in the middle.


    Anaphase - spindle fibres attach to retract back toward the centrioles splitting the centromeres and separating the chromosomes bringing them toward the poles, this is the fastest phase.


    Telophase - the chromosomes turn into chromatin, spindle fibres dissolve, nuclear membrane forms around the two identical sets of chromosomes.


    Binary fission/ cleavage furrow/ cell plate - the cell separates into two.

  • Anabolism is the building up of larger molecules from smaller molecules using energy.

  • Remember: A for Anabolism, A for Adding.

  • Example: Protein synthesis


    • Catabolism is the breaking down of large molecules into smaller molecules with the release of energy.

    • Example: Digestion
