  1. Types of Plants Nonvascular and Vascular Plants

  2. Non-Vascular Plants Example: Mosses Characteristics: • No vascular tissue (system of tubes to transport 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 structures • Absorb H2O & nutrients c. Size – short, small Why?

  4. Non-Vascular Plants 4. Reproduction a. Seedless (have spores) b. Dependent on H2O 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 animals • Fuel (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: • Xylem – move nutrients & H2O UP from roots 2. Phloem – transports the products of photosynthesis in all directions

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

  10. Fern Structure • Size : can be taller than mosses Why?

  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 H2O 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 • Habitat • Food (Fiddleheads) • Fertilizer

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