  1. Kingdom Protista: Part 2

  2. Photosynthetic Phyla (the algae) • Myzozoa- dinoflagellates. • Euglenozoa- euglenoids. • Cryptophyta- cryptomonads. • Haptophyta- haptophytes. • Chlorophyta- green algae. • Rhodophyta- red algae. • Heterokontophyta- heterokont algae. • Phaeophyceae- brown algae. • Chrysophyceae- golden-brown algae. • Bacillariophyceae- diatoms.

  3. Cryptophyta- cryptomonads • Characteristics • Unicellular. • Chlorophylls A & C, phycobilins. • Food reserve- starch within 2 chloroplast membranes. • Thylakoids in 2. • Eukaryotic nucleus. • 2 flagella, both with hairs (dbl. & single). • No cell wall, proteinaceous periplast plates. • Habitat- marine & freshwater. • 200 species. • Examples- Cryptomonas.

  4. Haptophyta- haptophytes • Characteristics • Unicellular. • Chlorophylls A & C, fucoxanthin. • Food reserve- chrysolaminarin in vesicles. • Thylakoids in 3. • Eukaryotic nucleus. • 2 whiplash flagella and 1 haptonema. • No cell wall, covered with scales of cellulose or calcium carbonate. • Habitat- marine & freshwater. • 300 species. • Examples- Prymnesium & Phaeocystis.

  5. Chlorophyta- green algae • Characteristics • Unicellular and multicellular. • Chlorophylls A & B, carotenoids. • Food reserve- starch in chloroplast. • Thylakoids in 3-6. • Eukaryotic nucleus. • Highly variable; 0, 2, 4, multi-flagellated; whiplash when present. • Cell wall cellulosic. • Habitat- marine & freshwater. • 17,000 species. • Examples- Ulva, Codium, Chlorella, Volvox, Chara, Chlamydomonas, Closterium.

  6. Charales- Coleochaete

  7. Rhodophyta- red algae • Characteristics • Multicellular. • Chlorophylls A & D, phycobilins. • Food reserve- floridean starch in cytoplasm. • Thylakoids occur singly. • Eukaryotic nucleus. • No flagella. • Pit connections. • Cell wall with cellulose & galactans. • Habitat- marine & freshwater. • 6,000 species. • Examples- Polysiphonia, Porphyra, Batrachospermum, Corallina.

  8. Heterokontophyta- heterokonts

  9. Phaeophyceae- brown algae • Characteristics • Multicellular. • Chlorophylls A & C, fucoxanthin. • Food reserve- mannitol & laminarin in sac. • Thylakoids in 3. • Eukaryotic nucleus. • 2 flagella, 1 tinsel & 1 whiplash. • Cell wall cellulosic with alginate. • Habitat- marine. • 2,000 species. • Examples- Fucus, Macrocystis, Laminaria, Nereocystis, Ectocarpus, Sargassum.

  10. Chrysophyceae- golden-brown algae • Characteristics • Unicellular, colonial. • Chlorophylls A & C, fucoxanthin. • Food reserve- chrysolaminarin in vesicle. • Thylakoids in 3. • Eukaryotic nucleus. • Most= 2 flagella, 1 tinsel & 1 whiplash. • Cell wall cellulosic, silica, or none. • Habitat- marine and freshwater. • 1,000 species. • Examples- Dinobryon, Synura.

  11. Bacillariophyceae- diatoms • Characteristics • Unicellular, colonial. • Chlorophylls A & C, fucoxanthin. • Food reserve- chrysolaminarin in vesicles. • Thylakoids in 3. • Eukaryotic nucleus. • No flagella, or 1 tinsel on male gamete. • Cell wall is silica and made of 2 frustules. • Habitat- marine and freshwater. • 100,000 species. • Examples- Acnanthes, Bacillaria, Licmophora, Navicula, Coscinodiscus.
