Question

Name one evolutionary significant trait of Selaginella.

Answer 1

Selaginella:

1. Selaginella belongs to the Plantae Kingdom and the Pteridophyta Phylum.
2. Selaginella's heterosporous nature, which means they produce two types of spores, is an evolutionary crucial feature.
3. As a result, the development of seeds, also known as the seed habit, is the most important step in sexual reproduction and evolution.
4. The zygotes are generated when the male and female gametes unite.
5. The zygote continues to grow into an embryo.
6. The embryo's genesis and development take place within the female gametophyte.
7. For an extended period of time, the female gametophyte is kept on the parent sporophyte.
8. In higher vascular plants, the process of gamete development, fertilisation, and seed formation is comparable to this stage.
9. As a result, it is regarded as a crucial evolutionary predecessor.
