Read the given statements and select the correct option.Statement 1: ...
Bryophytes, the amphibians of the plants, show the following features:
  1. Dominant phase in their life cycle is haploid and gametophytic
  2. The gametic fusion forms sporophyte.
  3. The sporophyte is partially parasitic on the gametophyte and does not have independent existence.
  4. The spore mother cells undergoes meiosis and forms haploid spores.
  5. Spores germinate to form haploid generation again.
  6. They follow haplo-diplontic life cycle and sporic meiosis.
Community Answer
Read the given statements and select the correct option.Statement 1: ...
Explanation:
The correct answer is option 'A' - Both statements 1 and 2 are correct.

Statement 1: Bryophytes show alternation of generation.
Statement 2: A haploid gametophytic generation and a diploid sporophytic generation alternate in the life cycle.

Alternation of Generations:
The life cycle of bryophytes, including mosses, liverworts, and hornworts, exhibits alternation of generations. This means that the life cycle alternates between two multicellular generations - the haploid gametophyte and the diploid sporophyte.

Haploid Gametophytic Generation:
The gametophytic generation in bryophytes is haploid, meaning it has a single set of chromosomes. This generation produces gametes (sex cells) through mitosis. These gametes, which are also haploid, fuse to form a diploid zygote.

Diploid Sporophytic Generation:
The zygote develops into the sporophytic generation, which is diploid and produces spores through meiosis. These spores are haploid and can germinate to grow into new gametophytes, thus completing the cycle.

Explanation of the Correct Answer:
Both statements 1 and 2 are correct because they accurately describe the alternation of generations in bryophytes. Statement 1 correctly states that bryophytes show alternation of generation, while statement 2 correctly explains that a haploid gametophytic generation and a diploid sporophytic generation alternate in the life cycle of bryophytes. This alternation between haploid and diploid generations is a defining characteristic of the bryophyte life cycle.

In conclusion:
Bryophytes, such as mosses, liverworts, and hornworts, demonstrate alternation of generations. This cycle involves a haploid gametophytic generation that produces gametes and a diploid sporophytic generation that produces spores. Both statements 1 and 2 correctly describe this alternation of generations in bryophytes.

Gametophyte is a dominant phase in the life cycle of a bryophyte. It is more conspicuous, long living, independent, green and freely branched whereas, the sporophytic phase is short lived and dependent upon the gametophyte. The main plant body is haploid and bears sex organs i.e., antheridium and archegonium. Antheridium produces a large number of flagellated male gametes called antherozoids and archegonium is flask shaped with tubular neck and swollen venter. The gametophytic plant body of bryophytes is thalloid in liverworts whereas foliose in mosses. In liverworts, the thallus is differentiated into a dorsal photosynthetic and ventral storage region. In mosses, the gametophyte has two growth stages- protonema stage and leafy stage or gametophore.Direction : In the following questions the Assertions (
