One of the advantages would be mixing of genes; seedless plant offspring are identical to the parent, and thus all genetically similar offspring are vulnerable to the same factors as the parents ie. genetic deficiencies/bacteria or virus infection. A good example of this is the Irish potato famine.
No, seed plants out number seedless by a lot.
seed
when a seed begins to grow the young plant uses the food stored in the seed. the spores of the seedless plants dont have stored food to help a new plant grow.
seed plants
Bean plants are seed producing plants
when a seed begins to grow, the young plant uses the food stored in the seed. the spores of seedless plants don't have stored food to help a new plant grow. seeds can be spread by animals. the spores of a seedless plant are spread by wind. animals spread more efficiently than the wind spreads spores.
not
Seed plants produce seeds to overcome the adverse environmental conditions whereas seedless plants overcome the adverse environmental conditions by vegetative parts such as tubers, gemma cups or even spores. Since formation of seed involves genetic advance seed formation for reproduction is more successful in nature.
Seeds.
No they are seed plants!
A seedless plant has no seeds. A seed plant have seeds. It is very simple.
seed plants do not depend on moist habitats for reproduction way seedless plants do.
