  • Reproduction - A process by which organisms give rise to young ones (offspring) similar to itself
  • Asexual Reproduction - Requires only one parent
  • Asexual Reproduction - Offspring have 100% the same chromosomes as the parent
  • asexual reproduction - Most unicellular organisms reproduce this way
  • asexual reproduction - mitosis
  • binary fission - where every organelle is copied and the organism divides in two
  • budding - whereby a new individual develops from an outgrowth of a parent, splits off, and lives independently
  • Sporulation - Airborne cells that are released from the parent. They are enclosed and developed when the environment is appropriate
  • Regeneration - when a body part has broken off and the organism grows a new one
  • fragmentation - whereby a single parent breaks into parts that regenerate into whole new individuals
  • vegetative propagation - relies on multi-cellular structures formed by the parent plant
  • vegetative propagation - employed to multiply stocks of plants
  • sexual reproduction - Requires two parents that each share ½ of the genetic information.
  • sexual reproduction - Offspring share the characteristics of each parent
  • sexual reproduction - meiosis
  • allogamy - cross pollination
  • autogamy - self-pollination
  • Asexual reproduction produces more offspring
  • Asexual reproduction takes less time
  • asexual reproduction - Only one parent involved. No searching for mates
  • asexual reproduction - Requires less energy
  • sexual reproduction - Variation in offspring
  • sexual reproduction - organism is more protected because of genetic variation
  • sexual reproduction - Requires more cellular energy
  • sexual reproduction - More time required for offspring development
  • Flowers are the reproductive organs of plants
  • Sepals - The outermost whorls of a flower; collectively called the calyx
  • Petals - Whorl inner to the sepals; may be brightly colored in some; collectively called the corolla
  • Stamen - Whorl inner to the petals; the male reproductive structure of the flower; bears the male sporangia (also known as microsporangia)
  • Anther - Part of the stamen that contains the microsporangia that develops into pollen grains
  • Filament - Part of the stamen that serves as the stalk of the anther
  • Pistil or carpels - Innermost whorl of the flower; the female reproductive structure of the flower; bears the female sporangia (also known as the megasporangia)
  • Stigma - Part of the pistil where the pollen grain derived from the microsporangium attaches during pollination
  • Style - Part of the pistil that serves as the stalk of the stigma; leads to the ovary
  • Ovary - Found at the base of the pistil; contains one or more ovules; eventually becomes the fruit
  • Ovule - Contains the female sporangia or megasporangia; eventually becomes the seed
  • two way of sexual reproduction in animal kingdom
    1. internally
    2. externally
  • internally - the egg is fertilized by sperm inside the female.
  • Externally - The egg is fertilized by sperm outside the female
  • externally - The female lays the eggs and then the male fertilizes them
