Which one of the following is considered important in the developmental habit of a seed?
Correct answer: A. Heterospory
- A. Heterospory
- B. Haplontic life cycle
- C. Freeliving gametophyte
- D. Dependent sporophyte
Explanation
The sporophyte generation in plants is the diploid phase that produces spores through meiosis. In the case of seed plants (gymnosperms and angiosperms), the sporophyte is the dominant and long-lived phase of the life cycle. The sporophyte is responsible for producing and protecting the seeds, which are the reproductive structures of these plants.
