2.3 reproduction

• diploid


  2 sets of chromosomes (all cells apart from gametes)
• haploid


  1 set of chromosomes (gametes)
• gamete


  reproductive cell of animal or plant
• male reproductive system

  @testes
• female reproductive system

  @ovaries
• human egg


  outer layer of cells, nucleus, cytoplasm, mitochondria
• human sperm


  nucleus, cytoplasm, mitochondria, tail (to swim to egg)
• plant reproduction system

  petal, stigma, style, ovary, ovule, sepal, anther, filament
• female plant reproductive system

  pollen grains produced @anther
• male plant reproductive system

  ovules produced @ovary
• zygote


  diploid cell resulting from the fusion of two haploid gametes, a fertilised ovum
• embryo


  early stage of animal or plant development
• male ureter


  carries urine from kidney to bladder
• male sperm duct


  carries sperm from testes to penis
• male prostate


  produce seminal fluid
• male penis


  deposits sperm
• male testes


  produces male gamete / sperm cell
• female oviduct / fallopian tube


  site of fertilisation
• female ovary


  produces female gamete / egg cell
• female cervix


  allows fluids to pass from uterus to vagina
• female uterus


  where embryo develops
• female vagina


  where sperm is deposited
• plant petal


  attracts insects for pollination, protects reproductive organs
• plant stigma


  collects pollen
• plant style


  stalk connecting stigma and ovary, contains pollen tube, prevents incompatible pollen from entering
• plant ovary


  contains ovules that will be fertilised by pollen to develop into seeds
• plant pistil


  reproductive organs (stigma, style, ovary)
• plant ovule


  produces + houses egg cells
• plant sepal


  protective layer around unopened flower/bud
• plant anther


  produces pollen
• plant filament


  holds anther up
• fertilisation

  fusion of the nuclei of 2 haploid gametes to produce a diploid zygote which divides to form an embryo
