Topics in Reproduction in Plants

1

Modes of Reproduction

  • Reproduction ensures the continuation of species and replaces dead individuals.
  • Three main modes: Vegetative, Asexual, and Sexual reproduction.
  • Vegetative and asexual reproduction involve one parent and produce genetically identical offspring (clones).
2

Reproduction in Lower Plants

  • Chlamydomonas reproduces asexually by zoospores, aplanospores, and hypnospores depending on water availability.
  • Sexual reproduction in Chlamydomonas occurs via isogamy, anisogamy, or oogamy.
  • Meiosis occurs in the zygote stage, producing haploid zoospores.
3

Sexual Reproduction in Angiosperms

  • Flower is the reproductive organ of angiosperms.
  • Essential whorls: Androecium (male) and Gynoecium (female); non-essential: Calyx and Corolla.
  • Stamen consists of filament and anther; anther contains microsporangia where pollen grains develop.
4

Pollination and Fertilization

  • Pollination: Transfer of pollen grains from anther to stigma.
  • Types: Self-pollination (same flower) and cross-pollination (different flowers of same species).
  • Agents: Wind (anemophily), insects (entomophily), water (hydrophily), animals (zoophily).
