Rhizoids in pteridophytes are hair-like structures that absorb water and minerals, functioning similarly to roots in higher plants.
Bryophytes have a dominant gametophytic generation with a dependent sporophytic generation, unlike other plant groups where the sporophyte is dominant.
A sorus (plural: sori) is a cluster of sporangia arranged on the abaxial surface of fern leaves, often covered by an indusium for protection.
Presence of archegonia, independent dominant gametophyte, and absence of true roots are distinctive features of bryophytes including mosses and liverworts.
The ovule arises as an outgrowth from the placenta (megasporophyll) and projects into the ovary cavity.
The prothallus is the free-living, independent, heart-shaped gametophytic generation in ferns that produces archegonia and antheridia.
Naked ovules (not enclosed in ovary) and cone formation are characteristic features of gymnosperms. Angiosperms have ovules enclosed in the ovary.
The gametophyte generation is always haploid (n) because it develops from spores after meiosis and produces gametes through mitosis.
Gymnosperms possess the most advanced vascular tissue with secondary growth, vessels in some species, and efficient water transport mechanisms compared to other groups.
Monocots have ONE cotyledon, not two. Two cotyledons is a characteristic feature of dicots. Options A, B, and C are all typical monocot features.
