How are spores structurally different from seeds
how are spores structurely different from seeds of plants. Spores are single cells with a haploid genome that have very little stored nutrients and water. They divide and grow to become a gametophyte. Spores are equivalent to pollen (the male, 2 celled gametophyte) rather than seeds.eeds are sporophytes. They are large & multicellular with a diploid genome formed from the merger of two gametes and endosperm formed from the merger of the central cell and a male sperm nuclei making it triploid. Seeds have a growth period before they go dormant for release.
