1. PLANT DIVERSITY

2. SUPERGROUP ARCHAEPLASTIDA – KINGDOM PLANTS

3. SPORE

4. GAMETOPHYTE

5. GAMETOPHYTE SHEDDING SPORE COAT

6. MATURE GAMETOPHYTE (HERMAPHRODITIC) Antheridia (male) Archegonia (female) Rhizoids

7. EGG IN ARCHEGONIUM

8. FLAGELLATED SPERM COMING OUT OF ANTHERIDIUM

9. Colonization of Land – Adaptive Radiation Limitations for terrestrial life – Water availability – Dispersal mechanisms – Maintaining genetic diversity Result = great diversity of land plants

10. Vascular Tissue Long tubes: transport water minerals and nutrients. – Phloem: sugars/nutrients from leaves – Xylem: wter and minerals from roots Made of special cells called tracheid cells Tracheophytes

11. Alternation of generations Haploid generation (1n) Gametophyte Haploid gametes fuse to form diploid zygote – Diploid generation (2n) Sporophyte Produce haploid spores through meiosis

12. Moss and Liverwort Life Cycle Gametophyte is dominant form Lack of vascular tissue – Low to the ground Swimming sperm (dependent on water)

13. Fern Life Cycle Sporophyte is dominant form Vascular tissue present – Can grow taller Swimming sperm (dependent on water)

14. Pine Life Cycle Sporophyte is dominant form Vascular tissue present Dispersal ability – Sperm in pollen – Seeds

15. Angiosperm Life Cycle Sporophyte is dominant form Vascular tissue present Flowers – Pollination (dispersal and genetic variability) – Double fertilization

16. TODAY’S LAB Fill out Table 5.2 with plant characteristics – study for quiz Lab Report due next week: fern lifecycle Plant presentations
