Question

Is Tepal and Perianth the same?

Answer 1

Tepal and perianth are both parts of flowering plants. Flowering plants also known as angiosperms are the most diverse group of land plants. Like gymnosperms they also produce seeds but unlike gymnosperms they produce flowers as well as fruits containing seeds.

Complete answer:
Angiosperms or flowering plants are known to have few distinguishing features such as flowering organs that allows them to have a more species-specific breeding system. The stamens of angiosperms are much lighter than those of the gymnosperms. The stamens are also modified to prevent self-fertilization and promote pollination by particular pollinators. The male gametophyte of angiosperms are reduced as compared to gymnosperms. The smaller size of the pollen is advantageous as it reduces the time taken to reach the female plant and carry out fertilization. The female gametophyte is also reduced like the male gametophyte. Angiosperms also have closed carpels that upon fertilization may develop into fruit. Angiosperms also contain endosperm that begins to develop after fertilization and helps in providing food and nutrition for the developing embryo. Coming to the given question, perianth is defined as the non-reproductive part of a flower that is known to form an envelope around the sexual organs and tepal is known to be the outermost part of the flower. Tepals are collectively called as perianth, so they are the same.

Note:
Flowering plants are of importance mostly because many of them produce agriculturally important crops such as rice, wheat, maize, etc.; vegetables such as potato, pumpkins, tomato, etc. and fruits such as lemons, oranges, grapefruit, etc. Apart from these they also produce economically important resources such as paper, wood, camphor, etc.
