They develop flowers, which have distinct and grateful shapes, colors, smells, chemicals, and nectar to string insects and birds, which attention in pollination. Males developed microspores, which is pollen, and a reduced gametophytes. The pollen tittle became very light weighted and considerably blown to the highest degree in tack to increase motility. It is now possible for pollination to befall by wind, insects. In fact, many plants can withal self-pollinate. The womanish also developed a reduced gametophytes, in the macrospore or the mega sporangium.

Nature had to recrudesce protection for the gametophytes, and it came up with an conceptus inside the ovary, carpel, or pistil. The generator also evolved a rigid protective covering to back up in reproduction. spill became carried in fruits, which were eaten by animals that dispersed the generators and aid in reproduction. In addition, seed dormancy allows the seed to delay latent for all-inclusive periods of time. Lastly, the phylogeny of internal fertilization exploitation the pollen tube and endosperm helped plants overcome the pretermit of aquatic environment...
