Grade 7-algae

  1. 1. Other Organisms Besides Plants & Animals
  2. 2. FUNGI
  3. 3. PROTISTS
  4. 4. Protists • It is actually an obsolete term that describes plant-like, animal-like, and fungus-like organisms (mainly unicellular).
  5. 5. Protists • Today, this term is not preferred by biologists because they have shown that these organisms are either plants, animals, fungi, or belonging to their own unique group.
  6. 6. Today, let’s start with the plant-like organisms / plant- like protists
  7. 7. ALGAE Plant-like Organisms
  8. 8. Algae • Eukaryotic, unicellular or multicellular organisms • Most are aquatic and autotrophic • Have chlorophyll as the main pigment for photosynthesis • No true roots, stems, or leaves • PRODUCERS of aquatic habitats
  9. 9. Groups of Algae • Green Algae • Red Algae • Brown Algae • Dinoflagellates • Euglenids
  10. 10. Green Algae • Contain chlorophyll in their chloroplasts • Has cell walls made of cellulose • Most scientists today consider them as plants • Has unicellular and multicellular forms • No true roots, stems, or leaves
  11. 11. Chlorella • Unicellular green algae • High in protein and other nutrients – used in food supplements • Excessive growth can sometimes cause problems in lakes, aquaria, etc.
  12. 12. Red Algae • They are red because of the pigment phycoerythrin • Mostly live in the ocean – seaweeds • Source of carrageenan and agar – gels that can be used for a variety of purposes
  13. 13. Gulaman (agar-agar) Nori
  14. 14. Brown Algae • They are brownish because of the pigment fucoxanthin • Mostly live in the ocean – seaweeds • Largest and the fastest growing of all seaweeds • Can be a food source
  15. 15. Sargassum
  16. 16. Giant Kelp
  17. 17. Dinoflagellates • Unicellular organisms that could do photosynthesis though some combine photosynthesis and ingesting food • Excessive growth (Algal bloom) causes death of marine organisms
  18. 18. Harmful algal bloom (red tide) caused by dinoflagellates
  19. 19. Euglenids • Unicellular organisms with chloroplasts and flagella
  20. 20. Euglena

Hinweis der Redaktion

  • Colonies of algae
  • Seaweeds
  • Lumot
  • Pronounced as “Al-jee” [singular: alga – “al-ga”]
  • OTHER examples of red algae
  • Mixotroph = combination of autotroph and heterotroph
    Algal bloom = red tide
