Types of Plants

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
1. Seedless Vascular plants Ferns

• 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 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
