Which characteristic led to the evolution of seed?
Correct answer: B. Development of heterospory
- A. Heterogamous condition
- B. Development of heterospory
- C. Embryo formation
- D. Protection of reproductive cells
Explanation
The development of heterospory is indeed a crucial step in the evolutionary pathway that eventually led to the development of seeds in plants. Heterospory involves the production of two distinct types of spores: microspores, which give rise to male gametophytes (microgametophytes), and megaspores, which give rise to female gametophytes (megagametophytes).
