KEYWORDS


  • Asexual reproduction: The simple division of the plant body into two or more parts or spore formation in which a new plant body is formed from a single parent is called asexual reproduction in plants.
  • Sexual reproduction: The formation of seeds which involve two parents and the fusion of male and female reproductive cells is called sexual reproduction in plants.
  • Budding: The process in which a small bulb-like cellular outgrowth is formed from the cell (bud) is called budding. e.g. yeast
  • Embryo: Fertilized egg is called zygote. Zygote develops into an embryo.
  • Fertilization: The fusion of male and female gametes is called fertilization.
  • Fragmentation: The act or process of breaking into fragments is called fragmentation. e.g. spirogyra
  • Gametes: The fusion of male and female reproductive cells called that form a single cell are called gametes.
  • Ovule: The female reproductive structure that develops into a seed in a seed-bearing plant is called ovule.
  • Pollen grain: A structure produced by plants containing the male gamete to be used in reproduction is called pollen grain.
  • Pollen tube: The slender tube formed by the pollen grain that penetrates an ovule and releases the male gametes.
  • Pollination: The transfer of the pollen grains to the stigma of the pistil is known as pollination.
  • Seed dispersal: The process in which seed(s), enclosed in the fruit, separate/s from its parent plant before it can develop into a new plant is called seed dispersal.
  • Spore: The asexual reproductive body which is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and low humidity is called a spore.
  • Zygote: The cell which results after fusion of the gametes is called a zygote.
  • Reproduction: The process of producing young ones from their parents is known as reproduction.
  • Stamen: The male reproductive organ of a flower, consisting of a stalk (filament) bearing an anther in which pollen is produced is called stamen.
  • Pistil: The female, ovule-bearing organ of a flower, including the stigma, style, and ovary is known as pistil.
