In a heterosporous plant, what is the correct sequence of structures involved in the production of male gametes?

  • A: Megasporophyll → Megasporangium → Megaspore → Female gametophyte → Eggs
  • B: Microsporophyll → Microsporangium → Microspore → Male gametophyte → Sperm
  • C: Sporangium → Single type of spore → Bisexual gametophyte → Sperm
  • D: Strobili → Sori → Spores → Male gametophyte

Explanation

In heterosporous plants, male gametes sperm are produced following a specific pathway: Microsporophylls bear microsporangia, which produce microspores. These microspores then develop into male gametophytes, which subsequently produce sperm.
