Facts about Angiosperms

We all see beautiful flowers that decorate our gardens. These flowers are the reproductive organs that produce fruits that contain seeds. The word Angio means ‘closed’ and ‘Sperma’ means ‘seeds’. In angiosperms, the seeds are closed inside the fruits. Mango, oranges, rose, and hibiscus are examples of angiosperms. Let’s look at some of the interesting facts about angiosperms.

What are Angiosperms?

Angiosperms, the flowering plants are vascular plants with stems, roots and leaves. The seeds of the angiosperm are found in a flower. These make up the majority of all plants on earth. The seeds develop inside the plant organs and form fruit. Hence, they are also known as flowering plants.

Angiosperms are the most advanced and beneficial group of plants. They can grow in various habitats such as trees, herbs, shrubs, and bushes.

The angiosperms originated about 250 million years ago and comprise 80% of the earth. They are a major source of food for humans and animals.

Frequently Asked Questions on Facts about Angiosperms

Does every flower turn into fruit?

Almost every flower produces fruit. But, the fruit may be hidden or different from normal fruits. E.g.: Rose produce rose hips.

Why some flowers have rotten corpse smell?

Rotten corpse smell attracts house flies that are helpful in pollination.

How are flowers helpful in reproduction?

The colourful petals and nectar in flowers attracts bees and other insects for pollination. The male and female reproductive structures are present in the flower. The ovules develop into seeds which encloses the embryo. The ovary develops into fruit and it is involved in seed dispersion.
