Question

Ferns exhibit life cycle.

• A. haplontic
• B. diplontic
• C. haplodiplontic

Answer 1

Answer: (B), (C)

haplodiplontic

The main plant body in pteridophytes is a diploid sporophyte with well differentiated roots, stems and leaves. They also have a well-differentiated vascular tissue system.

The sporophytes are independent and may produce the same type of spores (homosporous) or different types of spores (hetrosporous) which germinate to produce independent haploid gametophytes. Thus, ferns exhibit a haplo-diplontic life cycle.
