Adifference between nonflowering seed plants and flowering seed plants is that ) flowering seed plants tend to have needles(b) nonflowering seed plants lack vasculature(c) nonflowering seed plants lack ovules(d) flowering seed plants lack flagellated sperm

The correct answer is D) flowering seed plants lack flagellated sperm

Explanation:

Flowering seed plants are also known as angiosperm. A difference between flowering seed plants and non-flowering seed plants is that flowering seed plants do not have flagellated sperms because they do not require water to carry their sperm towards female reproductive part.

Male gametes are present in pollen grains and the dispersal of pollen grains in flowering seed plants takes place by wild and they form a pollen tube which is used to transport the male gamete to the ovule of the flower which contains female gamete.  

Therefore the right answer is D) flowering seed plants lack flagellated sperm.
