Give two basic differences between bryophytes and pteridophytes.

Two fundamental differences between bryophytes and pteridophytes:

1. Vascular Tissue:

• Bryophytes: Lack vascular tissue (xylem and phloem), making them non-vascular plants. Water and nutrients move through simple diffusion and osmosis, limiting their size.
• Pteridophytes: Possess well-developed vascular tissue (xylem and phloem) for efficient transport of water, minerals, and nutrients, enabling larger plant size and better terrestrial adaptation.

1. Dominant Generation:

• Bryophytes: The gametophyte (haploid) generation is dominant and conspicuous, while the sporophyte depends on the gametophyte for nutrition (e.g., moss plants are gametophytes).
• Pteridophytes: The sporophyte (diploid) generation is dominant and independent, while the gametophyte is small and often short-lived (e.g., fern plants are sporophytes).

These differences reflect pteridophytes' more advanced evolutionary adaptation to terrestrial life compared to bryophytes.
