Question

five important features of angiosperm

Answer 1

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.

✔️Timber:
many angiosperms particularly dicot yield valuable hardwood which is used as Timber e.g., Teak, Oak, Sheesham, Sandalwood, etc.

✔️Fibres:
Fibres of different qualities are obtained from various species of flowering plants e.g., Textile fibres are obtained from cotton.
