3. Gymnosperms
Ferns & Relatives
Bryophytes

4. Gymnosperms – “naked seed”
Have vascular tissue
Mostly wind pollinated

5. Groups

9. Cones & Seeds

10. Angiosperms

11. Gymnosperms
Angiosperms
Ferns & Relatives
Bryophytes

12. Angiosperm Facts
Angiosperms have a unique reproductive organ called FLOWERS
Many produce fruit = a wall of tissue surrounding a seed
The seed leaves of plant embryos are called cotyledons
Flowers that complete an entire life cycle within one growing season are called –annuals
Most are pollinated by animals

13. Angiosperms Have vascular tissue Mostly wind pollinated
Flowers – evolutionary advance
Contain reproductive structures
Attract pollinators
Ovary develops into protective fruit
2 groups: Monocots & Dicots

14. Monocots Monocots Cotoledons = 1 Root Type = Fibrous
Stem Vascular Bundles = scattered
Leaf Venation = parallel
Flower Parts = in multiples of 3

15. Dicots Dicots Cotoledons = 2 Root Type = Tap
Stem Vascular Bundles = Ring arrangement
Leaf Venation = Branched
Flower Parts = in multiples of 4 or 5
