• Life is everywhere we look, it ignites all of our actions, it is both fleeting and enduring, boundless and transient
• The human species seems insignificant beside the power of nature and the breadth of the life by which we are surrounded and yet we have dominion over it all
• When does life begin?

  When a fetus becomes somewhat identifiable and systems are developing, when they're born, when they actually breathe
• We're not gonna know when life actually begins, not even in a thousand years, not even in a million years
• The unborn take in nutrients and grow via cellular reproduction
• The unborn are the offspring of human parents and have human DNA
• The unborn are human organisms like you or me, whereas sperm, egg and body cells are merely human tissue and do not have any rights
• Adult, teenager, child, infant, fetus, embryo, zygote are all stages of development in the life of a human organism
• We should treat all human organisms or what we usually call human beings equally regardless of what level of development they're currently at
• Stamen


  The male reproductive part of the flower, consisting of the anther and the filament
• Anther


  Produces pollen grains, each containing a tube cell with a tube nucleus and two male gametes
• Carpel


  The female reproductive part of the flower, with the stigma at the top, supported by the style, and the ovary at the base
• Ovule


  Contains a female gamete
• Sexual reproduction in flowering plants


  1. Pollen grains land on the stigma

  2. Pollen tubes extend down to the ovary

  3. Ovules are fertilized

  4. Seeds formed
• Flowering plants or angiosperms reproduce sexually, and the flower is the reproductive organ
• Flowers contain male reproductive organs (anthers) and female reproductive organs (carpels)
• Pollen contains the male gametes and is found on the anthers
• Pollen moves from the anthers to the female stigma
• Pollen tubes extend down to the ovary where the ovules are fertilized and seeds formed
• Seeds mature either inside fruit or in the ovary and are dispersed in a number of ways
• Many flowers contain both male and female organs and gametes, while some have only one type of reproductive organ
• Plants containing both male and female organs are able to self-pollinate, although cross-pollination ensures genetic diversity
• Pollen is unable to move on its own, it is transferred from anthers to stigmas by various means including birds, insects, wind and water
• Sexual reproduction in flowering plants is a highly evolved process, they are very successful organisms with an estimated 400,000 species in existence, and their reproductive process is critical to the survival of habitats worldwide
