Study Notes

Plant Reproduction Terminology

  • Sepals: Leaf-like structures that protect the flower bud.
  • Stigma: Sticky top of the style, designed to catch pollen (feathery in wind-pollinated plants).
  • Style: Stalk connecting the stigma to the ovary.
  • Ovary: Part of the flower containing ovules; develops into a fruit after fertilization.
  • Ovules: Tiny structures that contain female sex cells, developing into seeds after fertilization.
  • Pollen: Tiny granules containing male sex cells.
  • Fertilization: Fusion of pollen and ovule nuclei.
  • Pollination: Transfer of pollen from an anther to a stigma.
  • Cross-pollination: Transfer of pollen from one plant to another.
  • Self-pollination: Transfer of pollen from an anther to the stigma of the same plant.
  • Seed dispersal: Movement of seeds away from the parent plant.
  • Fruit: Swollen ovary containing fertilized seeds.
  • Stamen: Male part of the flower (anther and filament).
  • Carpel: Female part of the flower (stigma, style, and ovary).
  • Anther: Pollen-producing part of the stamen, located on top of the filament.
  • Filament: Stalk supporting the anther.
  • Nectar: Sweet liquid produced by flowers to attract pollinators.
