<h2>Fertilization in the absence of environmental water</h2>

Explanation:

  • About 360 million years ago, seeds appeared on Earth.
  • The seed bearing plant is divided into two categories:
  • Gymnosperms (naked seeds)
  • Angiosperms (seeds enclosed in ovary)
  • Seed bearing plant produce Microspores which leads to the formation of pollen grains. The pollen grain serve as a carrier for the sperm to the egg.
  • Seed bearing plant produce Megaspores, which formed within the ovules, and results into the formation of seed, when sperm fertilizes with the egg.
