Vascular Plants

2. Vascular Plants
Have vascular tissues
Longer sporophyte stage

3. Vascular Plants Club Mosses Similar to non-vascular mosses
Have SPORANGIA – reproductive structures that produce spores, look like clubs

7. Vascular Plants Horsetails Similar to club moss
Sporangia form cone-like structures

10. Vascular Plants Ferns – has roots, stems and leaves
Main stem grows underground – RHIZOME

11. Vascular Plants
FRONDS – leaves of ferns, clusters of sporangia are here
Reproduction for all three has to be in a moist environment

14. Seed Bearing Plants What is a seed?
An embryo with a food supply enclosed in a tough coat
Two types – gymnosperms and angiosperms

15. Seed Bearing Plants Gymnosperms – 1st seed bearing plants
Conifers – seeds develop on woody scales (form cones)
Reproduction does not have to be in a moist environment

16. Gymnosperms Sperm is enclosed in pollen
4 haploid cells leave, 2 disintegrate, leaving two attached to a wing

17. Gymnosperms
Redwoods
Fir
Pine

22. Angiosperms
Flowering plants
Produce fruit (contains the seeds)

25. Plant Parts Male = Stamen – anther and filament
Female = Pistil- ovary, style, stigma
Petals
Sepal – for protection

26. Plant Parts Stamen – whole thing Anther – pollen is produced
Filament- structure anther is on

27. Plant Parts Pistil – whole thing Ovary – where eggs are
Style – neck of ovary
Stigma – sticky part on top of style

28. Petal
Stigma
Style
