Answer: Angiosperms.
- A Bryophytes
- B Homosporous ferns
- C Angiosperms
- D Cycads (gymnosperms)
Correct answer: C. Angiosperms
Explanation: In angiosperms, microspores are produced in anthers (microsporangia) and megaspores in the ovule (megasporangium). This represents the complete development of heterospory into the seed habit.
Plants evolved from water-dependent algae through increasingly land-adapted groups, gaining vascular tissue (Pteridophyta), then seeds (Gymnosperms), and finally fruit-enclosed seeds (Angiosperms) - each step reducing dependence on water for reproduction.
Concept context
Classification of plants from algae to angiosperms. Understanding plant diversity is essential for NEET.
