1. Vascular tissue: Pteridophytes have vascular tissue (xylem and phloem) that allows them to transport water and nutrients throughout the plant, while bryophytes lack vascular tissue and rely on diffusion for nutrient uptake.
2. Reproduction: Pteridophytes reproduce through spores produced in sporangia, while bryophytes reproduce through spores produced in capsules or specialized structures called sporophytes.
3. Size: Pteridophytes are typically larger and more complex in structure compared to bryophytes, which are generally small and simple in structure. Pteridophytes also have true roots, stems, and leaves, while bryophytes lack true roots and stems.

1. Vascular Tissue:
- Pteridophytes: Have vascular tissue (xylem and phloem) that transports water and nutrients throughout the plant.
- Bryophytes: Lack true vascular tissue and rely on diffusion for nutrient and water transport.
2. Root Structure:
- Pteridophytes: Have true roots that penetrate the soil for anchorage and nutrient absorption.
- Bryophytes: Have rhizoids, which are hair-like structures that anchor the plant but do not have the ability to absorb nutrients from the soil.
3. Life Cycle:
- Pteridophytes: Exhibit an alternation of generations life cycle, with a dominant sporophyte (diploid plant) and a short-lived gametophyte (haploid plant).
- Bryophytes: Have a dominant gametophyte phase, with the sporophyte being parasitic or dependent on the gametophyte for nutrition.
