Developmental Biology - Coggle Diagram

- - - - Halves genetic material by producing gametes - sperm and egg
    - - Produces haploid sperm and egg
        
        Spermatogenesis
        
        Oogenesis
    - - Brings haploid gametes together to form new individual
      - Activates developmental process in the egg
      - Fertilised eggs are the only cell with capacity to form new unique individual
  - - - Function together within organism
        
        Thus process of embryonic development gives rise to higher-level structures arranged in a particular way in three dimensions
- - - - Simplicity -cell lineage, fate maps
      - Quick - 3.5 days, Sequenced genome
    - - Genetics
  - - - Accessible, observable
      - Maniqulation
      - Quick - 4 days
    - - Biology known
      - Genome sequenced
      - Molecular techniques
      - Transgenic mice
- - - - Adherence to surfaces
      - Biofilm formation
      - Twitching motility
- - - - Turns blastula into three germ-layered gastrula
      - Marked by extensive cell movment
      - 3 layers
        
        Ectoderm - outer
        
        Skin, nervous system
        
        NS forms on outside and internalises
        
        Mesoderm - middle
        
        Bone, blood, muscle, some organs such as kidneys
        
        Endoderm - inside
        
        Respiratory tract, digestive tract
    - - Blastual/blastoderm
