This document classifies and describes different types of plants. It divides plants into two main groups: flowering plants and non-flowering plants. Flowering plants are further divided into angiosperms, which produce fruits containing seeds, and gymnosperms, which have small flowers and develop seeds in cones instead of fruits. Non-flowering plants include ferns, which reproduce via spores and have roots, stems, and large frond-like leaves, as well as mosses, which have simple stems, leaves, and reproduce via spores inside capsules. The document also describes key parts of plants like leaves, roots, stems, and the process of photosynthesis by which plants produce their own food.
