FERNS AND THEIR RELATIVES
  • FERN
  • CLUB MOSSES
  • HORSETAILS

4
Ferns and their relatives share two
characteristics
  • VASCULAR TISSUE
  • 2. USE SPORES TO PRODUCE

5
VASCULAR PLANTS
  • Are much better suited to life on land than
    nonvascular plants.
  • Vascular tissue-
  • Strengthens plants body.
  • Transports food and water
    throughout the plant

6
Ferns produce spores
  • Spores grow into gametophytes.
  • Gametophytes produce egg and sperm cells.
  • Water is needed for fertilization to occur.

More Ferns

FERNS
  • Have underground stems, leaves and roots.
  • Roots anchor fern to the ground
  • absorb water and nutrients from
    soil.
  • Leaves of ferns are fronds.

Fronds (fern leaves)
Sporophyte stage
11
Sporophyte state
  • Spores develop in tiny spore cases on the
    underside of the fronds..
  • Later, spores are released.
  • When a spore lands in moist, shaded soil, it
    develops into a tiny gametophyte.

12
What are the main characteristics of seedless
vascular plants?
13
  • They have vascular tissue.
  • They use spores to reproduce.
