Which of the following statements is true ?

All pteridophytes exhibit haplodiplontic pattern. It is characterised by the presence of a dominant, independent,
photosynthetic, vascular plant body, known as the diploid sporophyte. This diploid sporophyte represents the main phase of the life cycle. Alternating with the sporophyte is a separate, multicellular, haploid gametophyte stage. The haploid gametophyte (prothallus) is autotrophic. It functions independently but has a relatively
short lifespan.

(2) Seed-bearing plants, which include gymnosperms and angiosperms, exhibit a diplontic life cycle. Though
they exhibit alternation of generation in their life cycle, sporophytic stage (2n) is the dominant stage whereas the gametophytic phase (n) is the highly reduced, dependent stage.

(3) Algae exhibit a wide range of life cycles, and it is not accurate to categorize most algal genera as diplontic. Algal life cycles can vary signifi cantly, including haplontic, diplontic and haplo-diplontic patterns.

(4) Bryophytes, which include mosses, liverworts and hornworts, exhibit a haplo-diplontic life cycle. They exhibit
alternation of generation in their life cycle. However, the gametophytic stage (n) is the dominant stage. while the sporophytic phase (2n) is dependent stage.
