Types of Plants Nonvascular and Vascular Plants Non-Vascular Plants Example: Mosses Characteristics: 1. No vascular tissue (system of tubes to transport water & nutrients) 2. Transport via diffusion 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? 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 Moss Life Cycle Moss Gametophyte with single sporophyte Non-Vascular Plants 5. Habitat -wetlands 6. Ecological Roles : • Habitat for animals • Fuel (peat) • Soil improvement (peat) Vascular Plants 1. Seedless Vascular Plants Examples: Ferns 2. Seed Plants Examples: trees, flowering plants What is Vascular Tissue? Definition: system of tubes for transport Location: in “true” roots, stems, leaves Examples: 1. Xylem – move nutrients & H2O UP from roots 2. Phloem – transports the products of 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 Fern Structure • Size : can be taller than mosses Why? 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 Fern Reproduction v. Alternation of generations Sporophyte is dominant generation Fern Life Cycle Ferns d. Habitat : moist areas e. Ecological Roles • Habitat • Food (Fiddleheads) • Fertilizer Vascular Plants 2. Seed Plants 1. Seeds in Cones 2. Seeds in Flowers = Flowering Plants
