reproduction

Cards (42)

  • fertilization
    fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo
  • zygote
    fertilized cell
  • gamete
    male and female "parts"
  • mitosis
    growth and repair
  • meiosis
    produces cells (gametes) that are not genetically identical
  • haploid
    half the amount of DNA of a normal cell - 23
  • diploid (double)

    full amount of DNA - 46
  • pollination
    the transfer of the male gamete (pollen) on the anther to the stigma
  • cross pollination
    pollen grains transferred to a different flower
  • self pollination
    pollen grains transferred from the anthers to stigma of the same flower
  • cotyledons
    first part of the plant to emerge from the seed (stores food - made of starch)
  • plumule
    first emerging shoot
  • radicle

    first emerging root
  • testa
    outercoat of the seed to protect the seed and content
  • micropyle
    opening in the testa to allow water to move into the seed
  • receptacle
    top part of stalks where flowers attatch
  • anther
    part of stamen - contains pollen
  • ovary
    eggs stored - joins with pollen
  • carpel
    female part - consists of stigma, style and ovary (makes seeds)
  • style
    supports stigma
  • stem
    green stalk - provide support
  • stigma
    catches pollen
  • stamen
    male part - contains anther and filament (makes pollen)
  • filament
    supports and holds anther - part of stamen
  • petal
    attract pollinating insects
  • sepal
    protects the buds
  • germination
    process by which plants grow from a seedling to a new flower/plant
  • cervix
    circular ring of muscle
  • uterus
    where the embryos grow
  • endometrium
    tissue lining of the uterus
  • ovary
    produces ova and sex hormones
  • testis

    makes sperm
  • scrotum
    holds the testes outside the body
  • sperm duct
    muscular tube that stores sperm then forces along ejaculation
  • prostate glands
    produces liquid that's added to sperm
  • secondary sexual characteristics
    physical characteristics to prepare for sexual reproduction
  • FSH
    matures egg to a ovary - stimulates ovaries to release orestrogen
  • oestrogen
    controls FSH to mature 1 egg a month - stimulates pituitary glands to release LH
  • LH
    causes matured egg to be released from the ovary - ovulation
  • progesterone
    maintains the endometrium during pregnancy
