2. Four Types of Plants Non-vascular Vascular Gynosperms Angiosperms

3. Nonvascular plants: Mosses Characteristics no water transport system rhizoids used to anchor spores for reproduction no seeds Where must mosses live?

4. Peat Bog “Peat Moss”

5. Primitive Vascular Plants: Ferns Characteristics internal transport system xylem/phloem & roots swimming sperm need water to reproduce spores for reproduction no seeds First true roots, stems, leaves spores Where must ferns live?

6. Ancient Tree Ferns Carboniferous forest – 290-350 mya Forests of ferns & mosses decayed into deposits of coal & oil Fossil fuels… I get it!

7. Ferns - adaptations See the first true Roots Stems Leaves Still considered primitive because ferns are still dependent on water for reproduction

8. Gymnosperms (conifers) Characteristics internal transport xylem/phloem, roots seeds “naked” seeds in cone (no fruit) pollen sperm that doesn’t have to swim

9. Diversity in conifers

10. Cones & “naked” seeds

11. male female male (pollen) cones female cones sporangium & pollen pine embryo

12. Flowering plants Characteristics internal transport system xylem/phloem, roots flower specialized structure for sexual reproduction pollen sperm that doesn’t have to swim seeds within fruit

13. FLOWER FLOWER: specialized structure found in angiosperms

14. Anther Filament Stamen Stigma Style Ovary Carpel Sepal Petal Ovule Flower 4 rings of flower parts sepals petals stamens male carpel female
