HORTICULTURE

Detailed explanation-1: -They are primitive plants that do not produce seeds, fruits and flowers. They reproduce via spores. They depend on water for fertilization; hence they grow in moist environments. Both bryophytes and seedless vascular plants are primitive plants.

Detailed explanation-2: -As they are not flowering plants, bryophytes reproduce by spores instead of seeds.

Detailed explanation-3: -Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they do not produce flowers or seeds. They reproduce sexually by spores and asexually by fragmentation or the production of gemmae.

Detailed explanation-4: -Seedless vascular plants reproduce through unicellular, haploid spores instead of seeds; the lightweight spores allow for easy dispersion in the wind. Seedless vascular plants require water for sperm motility during reproduction and, thus, are often found in moist environments.
