Question 20

four main categories of plants and their key adaptations, as well as examples of plants in each group. The four categories are seedless nonvascular, seedless vascular, gymnosperms, and angiosperms. The key adaptations that arose over the course of plant evolution include vascular tissue, seeds, and flowers. Vascular tissue is divided into two types: xylem and phloem. Xylem transports water and nutrients from the roots to the rest of the plant, while phloem transports sugars and other nutrients from the leaves to the rest of the plant.
