Which plants do not have flowers and which roots?

Flowers are absent in most groups of plants, among which can be called algae, all terrestrial spore species (moss, mosses, horsetails, etc.). Also, gymnosperms such as conifers, cycads, etc. do not have these reproductive organs.

The roots of plants appeared after they began to have a divided body. At the same time, different vegetative parts began to perform different functions. All higher vascular plants necessarily have roots, since without them they would not be able to exist normally.
