Plant Classification
Characteristics:
1. Live in MOIST environments
•
2.
WHY?
Absorb WATER and NUTRIENTS from their
environment
•
NO vascular tissue! (thin cell walls)
Examples:
1. Mosses
•
Gametophyte is green and fuzzy
•
Sporophyte is long and slender with capsule at the
end
•
Peat moss is used in agriculture and gardening
•
Peat is used as fuel

Liverworts
•
Found on Moist Rock and Soil beside
streams
Examples:
1.
Hornworts

Gametophyte
Stemlike structure
Leaflike structure
Rhizoids
Characteristics:
1.
Have vascular tissue- system of tubelike
structures inside a plant that water, minerals,
and food move through
2.
Do NOT produce seed-reproduce with spores
3.
Live in moist surroundings so sperm can swim
to eggs
Examples:
1.
Ferns
•
Size range is small to 5 meters tall!
•
Fronds are FERN LEAVES
How are club mosses different from “true” mosses?
Examples:
1.
Club Mosses
•
Grow on moist
woodlands near
streams
Examples:
1.
Horsetails
•
Steams are jointed

2.
Characteristics:
1.
Seed plant that produce Naked Seeds
2.
Have needle-like or scale-like leaves and deep
growing roots
Examples:
1. Cycads- palm trees with cones
2. Conifers- Cone bearing plants; aka Evergreens
because they keep their leaves year-round
3. Ginkgoes- Ginkgo biloba
4. Gnetophytes- live in hot desert and tropical
rainforest
Look like Palm trees with cones
•Cone Bearing Plants
•Evergreens (keep leaves
year-round)
Only ONE species:
Ginkgo biloba
Live in hot deserts and tropical rainforests
Use POLLEN and SEEDS to
reproduce!
The scattering of seeds so they are away from the
parent plant.
1.
What are some ways that seeds are dispersed?
2.
What are the 3 parts of a seed?
Characteristics:
1.
Produce flowers
2.
Seeds are enclosed in fruits
Characteristics:
1.
FLOWER
•
Reproductive structure of an angiosperm
Characteristics:
1. FRUIT
•
Ripened ovary and other structures that enclose one or
more seeds
