This document discusses how plants can be classified based on their vascular and reproductive systems. Some key points are: 1) Plants are either vascular, meaning they have tubes to transport water and nutrients, or nonvascular, meaning they do not have tubes and must stay small and close to the ground. 2) Nonvascular plants include liverworts, hornworts, and mosses. Vascular plants include ferns, horse tails, and seed-bearing plants like conifers and flowering plants. 3) Vascular plants can be further classified as either seedless, reproducing through spores, or seeded, reproducing through flowers or cones.
