1. VASCULAR
PLANTS

2. Vascular Plants
plants that have tube-like cells in their roots, stems, & leaves that carry water and nutrients
Vascular Plants-
An adaptation that allows plants to grow very tall
Vascular comes from the Latin word “vasculum” which means “vessel”

3. Vascular Plants: 2 Types of Tubes
vascular plants have 2 different types of tube-like structures inside them
a) xylem
b) phloem
each one has a specific function (job)
think of tiny pipes...like a plumbing system
Xylem -
tube-like cells that carry water & dissolved minerals from the roots to the leaves
tube-like cells that carry food, which is made in the leaves, to all parts of the plant
Phloem-

5. Turn & Talk Time
Turn to your elbow partner and talk about what you notice about Phloem and Xylem. How are they alike and different.
Together create a way to remember these differences or similarities. Be prepared to share it with the class
10 minute timer

8. Seedless Vascular Plants
Characteristics:
Have vascular tissue
Reproduce by spores
Types: FERNS
First appeared on earth 400 million years ago
Over 12,000 species alive today
Popular house plants and used to grow other house plants

9. Seedless Vascular Plants
(Ferns continued)
usually grow in moist shady areas
typical fern
they have adapted to grow in other environments:
-aquatic (water)
-dry climates
-tropical regions

water horn fern
stem stores the food & water
tropical fern

10. Vascular Plants: Seedless (ferns)
4 Parts of a Fern:
an underground stem that anchored by the roots
rhizoid-
roots-
anchor the fern
Frond-
full grown leaves that stand vertically
Fiddlehead-
tightly coiled new leaves

11. Vascular Plants: Seedless (ferns)
4 Parts of a Fern:
roots-
rhizoid-
Frond-
Fiddlehead-

12. Vascular Plants: Seedless (ferns)
The Fern Reproduction
reproduce by spores formed on the underside of the leaf
the cases that hold the spores look like brown and orange spots

13. Seedless Vascular Plants
CLUB MOSSES
Very Small
Grows in moist woodlands and near streams

14. Seedless Vascular Plants
HORSETAILS
Only 30 species alive today
Stems are jointed and long, coarse, needle-like
Small leaves grow flat against stem
