Non-Vascular Plants
Types of Plants
Nonvascular
and
Vascular Plants
Non-Vascular Plants
3. Structure:
a. No “true”
true”
roots,
stems
or leaves
or cuticle
b. Rhizoids =
• rootroot-like structures
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
Example:
Mosses
Characteristics:
1. No
vascular tissue
2. Transport via
diffusion
Non-Vascular Plants
3. Structure:
c. Size –
short, small
Why?
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)
What is Vascular Tissue?
Definition: system of tubes for transport
Location: in “true”
true” roots, stems, leaves
Examples:
1. Xylem – move nutrients & H2O
UP from roots
2. Phloem – transports the products of
photosynthesis in all directions
Fern Structure
• Size : can be taller than mosses
Why?
Vascular Plants
1. Seedless Vascular Plants
Example: Ferns
2. Seed Plants
Example: trees, flowering plants
1. Seedless Vascular plants : Ferns
a. Structure
• True roots, stems & leaves
vascular tissue
• Frond = blade (leaf) of fern
• Cuticle on upper surface of frond
(Waxy covering, prevents
dehydration)
• Have Stomata
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
Fern Life Cycle
v. Alternation of generations Sporophyte is
dominant generation
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
