Characteristics of Angiosperms.

Angiosperms have diverse characteristics. The important characteristics of angiosperms are mentioned below:

➞All plants have flowers at some stage in their life. The flowers are the reproductive organs for the plant, providing them with a means of exchanging genetic information.

➞The sporophyte is differentiated into stems, roots, and leaves.

➞The vascular system has true vessels in the xylem and companion cells in the phloem.

➞The stamens (micro sporophyll) and the carpels () are organized into a structure called the flower.

➞Each micro sporophyll has four micro sporangia.

➞The ovules are enclosed in the ovary at the base of the mega sporophyll.

➞Angiosperms are hetero sporous, i.e., produce two kinds of spores, microspore (pollen grains) and megaspores.

➞A single functional megaspore is permanently retained within the nucelus.

➞The pollen grains transfer from the anther to stigma and reproduction takes place by pollination. They are responsible for the transfer of genetic information from one flower to the other. The pollen grains are much smaller than the gametophytes or reproductive cells present in the non-flowering plants.
