Evolutionary important character of Selaginella is
Correct answer: A. Heterospory
- A. Heterospory
- B. Rhizophore
- C. Strobili
- D. Ligule
Explanation
The evolutionary important character of Selaginella is heterospory.Heterospory is the production of two different types of spores: microspores and megaspores. Microspores are smaller and produce male gametophytes, while megaspores are larger and produce female gametophytes. Heterospory is a significant evolutionary advancement because it allows for the development of seeds.Rhizophore is a modified root that helps Selaginella to anchor itself to the ground.Strobili are cone-like structures that contain the spores of Selaginella.Ligule is a small tongue-like structure that is found at the base of the leaves of Selaginella.
