Angiosperms are vascular plants with leaves, stems and leaves. The seeds of angiosperms are found in the flower. These are the most abundant of all plants on earth. The seeds grow and produce fruit within the plant tissues. That is why they are also known as flowering trees.


Angiosperms are a very advanced and profitable group of plants. They can grow in a variety of habitats including trees, grasses, shrubs and bushes.

Characteristics of Angiosperms

All plants flower at some stage in their life. Flowers are the reproductive organs of a plant, which gives them a way to exchange genetic information.

  • The seeds are divided into leaves, stems and leaves.
  • The vascular system consists of true vessels in the xylem and synaptic cells in the phloem.
  • The seeds (microsporophylls) and carpels (megasporophylls) are arranged in a structure called a flower.
  • Each microsporophyll has four microsporangia.
  • The larvae are trapped in the underlying megaporophyll.
  • Angiosperms are heterosporous, that is, they produce two types of spores: microspores (pollen grains) and megaspores.
  • The active megaspore is held permanently within the nucleus.
  • Pollen grains are transferred from the cotyledon to the stigma, and fertilization occurs through pollination.
  • They are responsible for transferring genetic information from one flower to another.
  • Pollen grains are much smaller than the gametophytes or reproductive cells present in non-flowering plants.
  • Sporozoites duplicate.
  • The root system is complex and includes cortex, xylem, phloem and epidermis.
  • Flowers undergo double and triple fusion to produce diploid zygotic endosperm and triploid endosperm.
  • Angiosperms can survive in a variety of habitats, including marine habitats.
  • The reproductive process is rapid in angiosperms. Because female reproductive organs are smaller, sperm are also released faster.
  • All angiosperms contain stamens which are the reproductive structures of flowers. They form pollen grains that carry genetic information.
  • Carpels contain developing seeds that can become fruits.
  • The production of endosperms is one of the greatest advantages of angiosperms. After fertilization, the endosperm is produced and becomes the food source for the developing sperm and seeds.

Classification of Angiosperms

  • The seeds have a single shell.
  • The leaves are simple and the veins are compact.
  • This group has roots in porn.
  • Each flower tour has three members.
  • It has closed vascular segments and is large in number.
  • For example, bananas, sesame seeds and lilies.
