2. Vascular & Nonvascular Plants
A. Plants which contain vessels for transport
B. Xylem- vessels transporting water & minerals up to leaves
C. Phloem- vessel transporting sugar down to roots
D. Example-Flowers, Trees
1. Nonvascular
Plants without vessels for water & mineral transport
Example-Mosses

3. Bryophytes Nonvascular plants-Moss
Small, soft plants which grow in clumps
Absorbs water like a sponge
Live in moist, shaded areas
Height b/t 1-2 cm
Pioneer plants: break down rock

4. LIFE CYCLE
Reproduction: a. Alternate Generations: have 2 body forms in life cycle
b. Gametophyte- body form which produces gametes
c. Sporophyte- form which produces spores, grows from gametophyte
capsule
sporophyte
stalk
Stemlike structure
gametophyte
Leaflike structure

5. 2. Steps in Reproductive Cycle
Spore germinate & form gametophyte generation
Antheridium- forms male gametes(sperm)
Archegonium- forms female gametes(egg)
Sperm fertilizes egg & zygote is formed
Zygote divides and forms sporophtye

7. Seedless Plants Vascular plants- have xylem & phloem
Live in moist, fertile shaded areas
Form fronds (large leaves) leaves
Produce spores instead of seeds
Fiddlehead-young fern frond

8. 5. Reproduction: Alternate Generations
sporophyte & gametophyte are independent
spores released, germinate to form heart-shaped gametophyte called Prothallus
d. Prothallus prod. both Antheridium & Archegonium
e. Sperm released & swims through water & fertilizes egg
f. Zygote is formed & dev. in Sporophyte
