Angiosperms by an ovary or protected. They develop

Angiosperms have many distinguishing characteristics.  All angiosperms have flowers atsome stage in their life. These flowers are reproductive organs used to lure insects, birds andmammals such as bats so they can spread their pollen. Angiosperms also have small pollengrains that spread genetic information from flower to flower, and these grains are smaller thangametophytes, the reproductive cells of non-flowering plants. All angiosperms have stamens,which are reproductive structures found in flowers that produce the pollen grains that carry malegenetic information.

Angiosperms have much smaller female reproductive parts than non-flowering plants too, which lets them produce seeds more quickly. They have closed carpels,which protect developing seeds that might turn into fruit.  Finally, angiosperms use doublefertilization. This produces Endosperm, which serves as a food source for the developingseedling.Angiosperms were more successful in the Cenozoic Era in comparison to gymnosperms. Gymnosperms have vascular seed bearing plants in which the ovules are not surrounded by anovary or protected.

They develop their seeds on the surface of scales and leaves, which oftenform cone or stalk shapes. They use direct fertilization through pollination. However,gymnosperms primarily spread pollen and seeds through wind, whereas angiosperms are able toutilize various animals and insects to spread their pollen and seeds.

 Additionally, there is adifference in the Seedling Hypothesis for Angiosperm Dominance. Gymnosperms are woody andslow growing.  They have a lengthy reproductive cycle.

Young leaves thick and energeticallyconsuming to make, not changeable in shape.  Angiosperms have many herbaceous and fastgrowing and they have a short reproductive cycle. Leaves thing, energetically easy to make andvariable in shape.  Angiosperms also rapid seedling growth.
