  1. 1. Algae•Aitana•Marta•María
  2. 2. What´s an algae?•The algae comprise several different groups ofliving things which are similar to plants but arenot actually true plants.•Algae is aquatic organisms that do not haveroots, leaves or stems.
  3. 3. How does an algae eat?• they are autotrophic, obtaining their energy through photosynthesis
  4. 4. Algae types-Green algae(clocophyta)-Red algae(rhodophyta)-Brown algae(phaeophyta)
  5. 5. Phaeophyta(bronw algae)It includes a much-advanced group of algae, which are mostly marine forms.The name brown algae comes from the fact that they contain large quantities of a brown coloured pigment (fucoxanthin) which masks the colour of other pigments.
  6. 6. Rhodophyta(red algae)• They are generally found attached to rocky stones.• It is a group consisting of multicellular aquatic algae. •The members of this group are commonly called red algae due to the presence of a characteristic red pigment called phycoerythrin (red), which masks the colour of other pigments
  7. 7. Chlocophyta(green algae) • are the large group of algae from which the higher plants emerged. • Almost all forms have chloroplasts. These contain chlorophyll, giv ing them a bright green colour • Green algae are found attached to rocks.
  8. 8. Algae parts
  9. 9. USES• Despite of being an unknown group, algae offer a very big number of uses: -Nutritional (in food) -Agricultural (in farming) -Industrial (in industry) -Medical (in medicine)
  10. 10. Nutritional• Probably the most known use for algae.• In Spain, is not very popular but in other countries like Japan and China is used every day since more than 2600 years ago.• There are about 200 species used for human consume. The most used are:
  11. 11. The most used are:• Saccharina Japonica (“kombu” is used in meat, fish and soup)• Undaria Pinnatifida ( “Wakame” or “Miyeok”)• Porphyra (“Noi”)
  12. 12. Europe´s native species• Ulva• Himanthalia elongata• Porphyra dioica
  13. 13. Ulva algaeHimanth aliaelongat a Porphy ra
  14. 14. Agricultural• Mostly used as fertilizer• Most common are: -Ascophyllum nodosum -Fucus serratus -Laminaria
  15. 15. Ascophyl Fucus Lamina lum serrat rianodosum us
  16. 16. Industrial• Algae are used for cosmetics ,food and medicaments.• Most common are: -Gelidium sesquipedale -Pterocladia capillalea• Most common in Spain (used in milk products): -Chondrus Crispus -Mastocarpus Stellatus
  17. 17. Gelidium ChondrusPterocla Mastoca
  18. 18. Medical• During a lot of time algae have been used to treat illness like tuberculosis, flu and fam. Also for herpes and cancer.(Sargassum and Corallina)
