Determine whether each of the following is a characteristic of the life cycle of a seed plant, a seedless plant, or both. Double fertilization Gametophyte generation Endosperm formed Mitosis Spores develop into gametophytes

Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte

Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores - sporophyte)

Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition

Mitosis-both (mitosis occurres in spores)

Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
