tell me some more features of angiosperms
Answers
• All angiosperms have flowers at some stage in their life. The flowers serve as the reproductive organs for the plant, providing them a means of exchanging genetic information.
• Angiosperms have small pollen grains that spread genetic information from flower to flower. These grains are much smaller than the gametophytes, or reproductive cells, used by non-flowering plants. This small size allows the process of fertilization to occur quicker in the flowers of angiosperms and makes them more efficient at reproducing.
• All angiosperms have stamens. Stamens are the reproductive structures found in flowers that produce the pollen grains that carry the male genetic information.
• Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.
• Angiosperms have carpels that enclose developing seeds that may turn into a fruit.
• A great advantage for angiosperms is the production of endosperm. Endosperm is a material that forms after fertilization and serves as a highly nutritional food source for the developing seed and seedling.

Answer:
All plants have flowers at some stage in their life. ...
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 (microsporophyll) and the carpels (megasporophyll) are organized into a structure called the flower.
