Types of Plants Nonvascular and Vascular Plants

Non-Vascular Plants Example: Mosses Characteristics: 1. No vascular tissue (system of tubes to transport

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.

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

Non-Vascular Plants 4. Reproduction a. Seedless (have spores) b. Dependent on H 2 O

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

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

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,

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 2. Phloem – transports the products of

1. Seedless Vascular plants : Ferns a. Structure • True roots, stems & leaves

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

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
