Detailed explanation-1: -Angiosperms have flowers. The flowers are special structures for reproduction. They contain male parts that make pollen and female parts that contain ovules. Some plants have these male and female parts in different flowers.

Detailed explanation-2: -Angiosperms are the flowering plants. Their seeds develop inside a female reproductive part of the flower, called the ovary, which usually ripens into a protective FRUIT. Gymnosperms (conifers, Ginkgo, and cycads) do not have flowers or ovaries.

Detailed explanation-3: -Flowering plants grow from seeds Flowering plants produce seeds that are then dispersed from their parent. When a seed comes to rest in an appropriate place with conditions suitable to its germination, it breaks open. The embryo inside the seed starts to grow into a seedling.

Detailed explanation-4: -Both angiosperms and gymnosperms are vascular plants that reproduce by making seeds. Angiosperms are seed-producing flowering plants while gymnosperms are seed-producing non-flowering plants. The seeds of angiosperms are enclosed in ovary of fruit while seeds of gymnosperm are unenclosed and present in leaves or cones.

Detailed explanation-5: -Flowering plants reproduce sexually through a process called pollination. Flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. Pollen contains the male gametes.
