1. Types of Plants Nonvascularand Vascular Plants

2. Non-Vascular Plants Example: Mosses Characteristics: 1.No vascular tissue (system of tubes to transport water & nutrients) water & nutrients) 2. Transport via diffusion

3. Non-Vascular Plants 3. Structure: a. No “true” roots, stems or leaves or cuticle b. Rhizoids = root-like structuresroot-like structures Absorb H 2 O & nutrientsAbsorb H 2 O & nutrients c. Size – short, small Why?

4. Non-Vascular Plants 4. Reproduction a. Seedless (have spores) b. Dependent on H 2 O for sperm to swim to egg c. Alternation of generations - Gametophyte is dominant generation

5. Moss Life Cycle Moss Gametophyte with single sporophyte

6. Non-Vascular Plants 5. Habitat -wetlands 6. Ecological Roles : Habitat for animalsHabitat for animals Fuel (peat)Fuel (peat) Soil improvement (peat)Soil improvement (peat)

7. Vascular Plants 1. Seedless Vascular Plants Examples: Ferns 2. Seed Plants Examples: trees, flowering plants

8. What is Vascular Tissue? Definition: system of tubes for transport Location: in “true” roots, stems, leaves Examples: 1.Xylem – move nutrients & H 2 O UP from roots UP from roots 2. Phloem – transports the products of photosynthesis in all directions

9. 1. Seedless Vascular plants : Ferns a.Structure True roots, stems & leaves (vascular system) Transport via vascular tissue Frond = blade (leaf) of fern Cuticle on upper surface of frond Have Stomata

10. Fern Structure Size : can be taller than mossesSize : can be taller than mossesWhy?

11. 1. Seedless Vascular plants : Ferns c. Reproduction i. Seedless (use spores) ii. Spores in sporangia (spore cases) iii. Sporangia clustered in Sori iv. Dependent on H 2 O for sperm to swim to egg

12. Fern Reproduction v. Alternation of generations - Sporophyte is dominant generation

13. Fern Life Cycle

14. Ferns d. Habitat : moist areas e. Ecological Roles HabitatHabitat Food (Fiddleheads)Food (Fiddleheads) FertilizerFertilizer

15. Vascular Plants 2. Seed Plants 1. Seeds in Cones 2. Seeds in Flowers = Flowering Plants
