Which one of the following statements about bryophytes is not correct ?

Option D is the incorrect statement because bryophytes are non-vascular plants. Unlike tracheophytes (pteridophytes, gymnosperms, and angiosperms), bryophytes lack specialized vascular tissues, namely xylem and phloem, for the conduction of water and nutrients.

• Gametophyte: The main plant body of a bryophyte is a haploid gametophyte, which is the dominant and independent phase of its life cycle.
• Amphibians of the Plant Kingdom: They are given this title because they live on land but require a film of water for sexual reproduction, as their male gametes (sperm) must swim to reach the egg.
• Rhizoids: They lack true roots, stems, or leaves; instead, they use root-like structures called rhizoids (unicellular or multicellular) to anchor themselves to the substratum.

Because they lack a specialized conducting system, water movement occurs primarily through diffusion and capillary action.
