  2. 2. INTRODUCTION • The term ‘phycology’ is derived from Greek word ‘phykos’ which means ‘seaweed’. • It is the scientific study of algae and also known as algology. • Phycology is a branch of life science
  3. 3. GENERAL CHARACTARISTICS OF PHICOLOGY • Eukaryotic • Most unicellular but some multicellular • Produce oxygen that is returned to the atmosphere • Do not have true roots or leaves • Mostly aquatic although some are found in soil or on tress when sufficient moisture is present • Contain chlorophyll and carry out photosynthesis • Cellwall was thin and rigid. • No vascullar tissue • Cellwall is made by celluloge and pectin. • Reserve food starch.
  4. 4. CLASSIFICATION OF ALGAE • Chlorophyceae • Green Algae • Example:Volvox • Xanthophyceae • Yellow green algae • Botrydium
  5. 5. CONTINUE • Bacillariophyceae • Golden-brown algae • Example:Diatom • Phaeophyceae • Brown algae • Example:Laminaria
  6. 6. CONTINUE • Rodophyceae • Red algae • Example: Polysiphonia • Myxophyceae • Blue- green algae • Example:Nostoc
  7. 7. BODY STRUCTURE OF ULOTHRIX
  8. 8. REPRODUCTION OF ULOTHRIX LIFE CYCLE OF ULOTHRIX
  9. 9. WHY BLUE GREEN ALGAE(CYANOPHYCEAE CALLED CYANOBACTERIA??? BACTERIA • Advent in arkiojig era • prokaryotic • Cell wall is made by peptidoglycan • Amitosis cell divison • In outer part of the body has mucilage cover • 70s ribosome is present • Chlroplast,andoplasmic reticulum,golgi body,mitochondria is absent • Attacted by faz CYANOBACTERIA • Advent in Arkiojig era • prokaryotic • Cell wall is made by peptidoglykan • Amitosis cell division • In outer part of the body has mucilage cover • 70s ribosome is present • Chloroplast,andoplasmic reticulum,golgi body,mitochondria is absent • Attacted by faz
  10. 10. SPECIAL FEATURES OF ALGAE • Algae as superfood • 60% photosynthesis • To produce light • Sex organ are non-jacket
  11. 11. IMPORTANCE OF ALGAE • As food • To produce biofuel • In industry • As fertilizer • In pisi culture • To reduce environment pollution • As producer in ecosystem ADVANTAGE
  12. 12. DISADVANTAGE • To spread plant disease • Damages the deployment • To linged Roads • To create water bloom • To spread fish deases
