Which of the qualities is a major difference between all spore-dispersing and seed-dispersing plants? Select all that apply. The sporophyte of seed plants is photosynthetically independent. In seed plants, dispersed spores contain a multicellular gametophyte. The gametophytes of seed plants are never exposed to the external environment. Seed plants disperse gametes and seeds instead of spores.

These two apply.

1.) The sporophyte of seed plants is photosynthetically independent.

2.) In seed plants, dispersed spores contain a multicellular gametophyte.
