Reproduction - Biology - Coggle Diagram

- - - - Petals attract insects and small animals to the the flower for pollination and to protect the reproductive organs
    - - Stigma receives pollen
      - Style assists with fertilisation by helping pollen travel down the tube to deliver sperm cells to the egg.
      - Ovule has the eggs in them and receives pollen from a cargo sperm
      - Ovary prepares the ovules for fertilisation, protects developing zygotes, and makes seeds for ready for bearing fruit.
    - - Anthers are used to produce the pollen grains, which house male gametes or sex cells necessary for reproduction.
      - Filaments support the anther and carries nutrients to the anther for the development of tye anther and pollen tubes.
    - - Stem provides support for the plant, holding leaves, flowers, buds, etc.
    - - Sepals are leaves that protect the developing reproductive structure while the flower is still a bud
  - - - Pollination is the act of carrying out transferring pollen grains from the male parts (stamen) of one flower to the female parts (pistil) of another flower.
      - Pollinators:
        
        Bees
        
        Butterflies
        
        Flies
        
        Beetles
        
        Wasps
        
        Field mice
        
        Birds
  - - - Each pollen grain comes from different plants. Seeds come in different sizes, shapes, and colours. Some can be eaten and some can't. Some seeds germinate easily while some need certain criteria (tempreture, location, etc) before they germinate.
- - - - The menstrual cycle takes 28 days.
        
        Day 1 - 5: Uterus lining sheds, period occurs
        
        Day 6 - 10: Uterus lining thickens again in preparation for egg release from ovaries
        
        Day 11 - 18: Ovulation; egg gets released into the uterus
        
        Day 19 - 28: Lining thickens more, waiting for fertilisation
    - - Key points of labour
        
        Baby's head moves towards cervix
        
        Cervix dilates to about 10 cm
        
        Baby is delivered
        
        Placenta Separates
  - - - i tried attatching images, it didnt work lol
      - Functions:
        
        Ovary - storing eggs
        
        Uterus - growing feotus
        
        Vagina - passageway for fluids to exit body
        
        Cervix - releasing fluids into vagina and expands when giving birth
        
        Fallopian tubes - transports eggs to the uterus
    - - Functions:
        
        Penis - Sexual intercourse and urination
        
        Urethra - Passageway for bodily fluids
        
        Testicle - making sperm
        
        Vas Deferens - Tube for fluids
        
        Scrotum - keeping testicles safe
        
        Bladder - storing urine
  - - - Capital letters are always dominant
      - Homozygous - Homo means same, so two of the exact same gene (e.g bb, BB)
      - Heterozygous - Hetero means different, so two different genes. (e.g Bb)
    - - Fertilisation is when the lucky sperm meets the egg and they fuse to male an embryo/foetus
    - - Genes - contains the information needed for physical, biological traits and protein
      - DNA - contains the instructions for gene expression, replication and mutation or recombination
      - Chromosomes - a threadlike structure of protein in the nucleus of living cells, chromosomes carry genes from cell to cell
  - - - Key points

        Creating menstrual cycles
        
        Gain weight
      - Oestrogen is responsible for female puberty
    - - Testosterone is responsible for male puberty
      - Key points
