Angiosperms 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, also known as flowering plants, are the most diverse group of plants on Earth. They have several characteristics that set them apart from other plant groups. Let's delve into the details of these characteristics.

1. Flowers:
Angiosperms are defined by the presence of flowers, which are reproductive structures that produce seeds. Flowers are composed of four main parts: sepals, petals, stamens, and carpels. The diversity of flower colors, shapes, and sizes is one of the defining features of angiosperms.

2. Fruits:
After successful pollination and fertilization, angiosperms form fruits. Fruits are mature ovaries that protect and disperse the seeds. They come in various forms such as berries, capsules, drupes, and pods. Fruits play a crucial role in seed dispersal by attracting animals through color, scent, or taste.

3. Vascular Tissue:
Angiosperms have a well-developed vascular system that includes xylem and phloem. Xylem transports water and minerals from roots to shoots, while phloem carries sugars and other organic compounds throughout the plant. This efficient transport system enables angiosperms to grow taller and develop complex structures.

4. Broad Leaves:
Most angiosperms have broad leaves with a wide surface area. This adaptation allows for efficient photosynthesis, as the large surface area maximizes sunlight capture. The leaves also have stomata, tiny pores that regulate gas exchange and prevent excessive water loss.

5. Double Fertilization:
Angiosperms exhibit a unique reproductive process called double fertilization. Unlike other plants, where one sperm fertilizes the egg to form a zygote, in angiosperms, one sperm fertilizes the egg, while another fuses with two polar nuclei to form the endosperm. The endosperm provides nourishment for the developing embryo.

6. Dominance and Adaptability:
Angiosperms dominate most terrestrial ecosystems due to their adaptability. They can grow in diverse habitats, ranging from deserts to rainforests. This adaptability stems from their ability to produce a wide variety of flower structures, allowing for efficient pollination and reproduction.

7. Rapid Growth and Life Cycle:
Angiosperms have a relatively short life cycle compared to other plant groups. They typically exhibit rapid growth, flowering, and fruiting within a single growing season. This enables them to take advantage of favorable conditions and reproduce quickly.

In conclusion, angiosperms possess several characteristic features, including the presence of flowers and fruits, a well-developed vascular system, broad leaves, double fertilization, adaptability, and rapid growth. These traits have allowed angiosperms to become the most successful and diverse group of plants on Earth.

1. All angiosperms have flower at some stage in their life.
2. Angiosperms have small pollen grain that spread genetic information from flower to flower.
3. Angiosperms have stamen . Stamen are the reproductive structure found in flower that produce pollen grain that carry male genetic information.
4. Angiosperms have much smaller female reproductive part that bon flowering plant allowing them to produce seed more quickly.
