(i) Since reproductive processes such as pollination and fertilization are independent of water, seed formation is more dependable.
(ii) Seeds have better adaptive strategies for dispersal to new habitats and help the species to colonise in other areas.
(iii) As they have sufficient food reserves young seedlings are nourished until they are capable of photosynthesis on their own.
(iv) The hard seed coat provides protection to the young embryo.
(v) Being products of sexual reproduction, they generate new genetic combinations/variations.
(vi) Dehydration and dormancy of mature seeds are crucial for survival under adverse conditions.
