2. Plant Geneology & Taxonomy

3. I. NON-VASCULAR PLANTS No special system of vessels to transport fluids internally. Examples : mosses, liverworts

4. II. VASCULAR PLANTS Special vessel-like system for transmission of fluids internally. A. Non-Seed Bearing Reproduce through spores Examples : Horsetail, Ferns

5. II. VASCULAR PLANTS B. Seed-bearing: 1.Gymnosperms –Leaves are needle-like or scaly –Do not produce flowers –Many produce cones to protect seeds - conifers –Seeds not enclosed in fruit –Stems are woody Example : pines, redwood

6. II. VASCULAR PLANTS B. Seed-bearing 2. Angiosperms –Leaves are flat –Produce flowers –Seeds are enclosed in fruits –Stems can be woody or non-woody –Divided into two groups: monocots & dicots

7. II. VASCULAR PLANTS 2. Angiosperms a. Monocots –Flower parts in multiples of 3 –one cotyledon in seed –parallel leaf veins Example : grasses, corn

8. II. VASCULAR PLANTS: 2. Angiosperms: b. Dicots –Flower parts in multiples of 4 or 5 –two cotyledons –networked leaf veins Example : most other species
