DENDROLOGY

Detailed explanation-1: -The feature-They have finely divided leaves called fronds is not necessarily true for every flowering plant or angiosperms. This feature is seen mainly in the case of pteridophytes. However, the other features such as having stem, root, and leaves and production of seeds are characteristic features of angiosperms.

Detailed explanation-2: -Angiosperms do not produce cones and produce flowers/fruits instead. Gymnosperms are vascular plants that produce cones. Cones have their seeds exposed on the surface of their leaf-like structures instead of the seeds being enclosed in an ovary.

Detailed explanation-3: -Angiosperms. Angiosperms produce flowers, which are special structures for reproduction. They contain male parts that make pollen and female parts that contain ovules.

Detailed explanation-4: -The correct answer is they are seedless plants. A spermatophyte, also known as phanerogam is any plant that produces seeds. They are a subset of the embryophytes or land plants. It is classified into two parts: Gymnosperms and Angiosperms.
