In a comparative study, angiosperms might be more diverse than gymnosperms in various environments as:
Flowers and fruits aid pollination and seed dispersal
Angiosperms bear flowers, which attract insects, birds and other animals and allow many specialised modes of pollination.
Their seeds are enclosed in fruits, which are dispersed by wind, water and animals over wide areas, helping them colonise very different habitats.
Gymnosperms have no flowers or fruits (naked seeds, mostly wind pollination), and needle-like leaves are an adaptation of many conifers to cold or dry conditions rather than a cause of diversity; neither group depends on aquatic fertilisation.
Efficient water transport is found in both groups and does not explain the greater diversity of angiosperms.
Hence, the answer is flowers and fruits aid pollination and seed dispersal.
