Download Algae - Structure and Function of Plants - Lecture Notes and more Study notes Biology in PDF only on Docsity! Algae 1. Chlorophyta (Green Algae)- • 17,000 species • Unicellular and multicellular • Aquatic and in moist terrestrial habitats • Chlorophyll a and b • Storage = starch inside chloroplasts • Cellulose with hemicellulose, pectins • Zygotic and sporic meiosis in those we are considering. 2. What was required for algae to leave the water and colonize land? What links might we look for between specific algal groups and land plants? 3. Cellulose, hemicellulose, pectin 4. Starch stored in plastids 5. Chlorphylls a and b 6. Sporopollenin precursors – resist desiccation in spore walls 7. Cuticle precursors – protect vegetative structures from desiccation 8. Phragmoplast 9. Key connections to land plants… Green Algae  Cellulose, hemicellulose, pectin  Starch in plastids  Chlorophylls a and b  Sporopollenin precursors  Cuticle precursors (waxes)  Phragmoplast  Zygotic meiosis (zygote is the only diploid cell) 10. Phylogenetic Tree – reminder of relationships 11. Phylogenetic tree focusing on the green algae and land plants 12. Multicellular gametophyte, egg retention, phragmoplast 13. Coleochaete 14. Encasement of the egg on the gametophyte and sporopollenin around the zygote! 15. Charales – Docsity.com
