Given below are stages in the life cycle of a moss (bryophyte). Arrange the following stages in the correct chronological sequence starting from spore germination.
A. Formation of leafy gametophyte from protonema.
B. Germination of spores to form creeping green protonema.
C. Meiosis in the capsule of the sporophyte.
D. Development of sporophyte (foot, seta, capsule) from zygote.
E. Fertilization in the presence of water to form zygote.
Choose the correct answer from the options given below:
C, B, E, D, A
B, A, E, D, C
B, A, D, E, C
C, E, D, A, B
Start (B): Spores are released from the previous cycle and germinate to form the initial filament, the protonema.
(A): Lateral buds develop on the protonema to become the dominant, upright, leafy gametophyte phase.
(E): Male and female gametes (antherozoids and egg) are produced and fertilization occurs (requiring water). This forms the 2n zygote.
(D): The zygote remains on the gametophyte and develops into the parasitic sporophyte, which has a foot, seta, and capsule.
Finish (C): Inside the capsule of the sporophyte, spore mother cells undergo meiosis to produce the haploid spores needed to start the cycle again at step (B).
