This document provides an introduction to phycology, the scientific study of algae. It discusses the general characteristics of algae, including that they are eukaryotic, photosynthetic, and mostly aquatic. The document then covers the classification of major algae groups and provides examples. It examines the structure, reproduction, and life cycle of Ulothrix algae in more detail. Finally, it discusses the importance and uses of algae, as well as some disadvantages, and provides references for further information.

- 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. 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. CLASSIFICATION OF ALGAE • Chlorophyceae • Green Algae • Example:Volvox • Xanthophyceae • Yellow green algae • Botrydium
- 5. CONTINUE • Bacillariophyceae • Golden-brown algae • Example:Diatom • Phaeophyceae • Brown algae • Example:Laminaria
- 6. CONTINUE • Rodophyceae • Red algae • Example: Polysiphonia • Myxophyceae • Blue- green algae • Example:Nostoc
- 7. BODY STRUCTURE OF ULOTHRIX
- 8. REPRODUCTION OF ULOTHRIX LIFE CYCLE OF ULOTHRIX
- 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. SPECIAL FEATURES OF ALGAE • Algae as superfood • 60% photosynthesis • To produce light • Sex organ are non-jacket
- 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. DISADVANTAGE • To spread plant disease • Damages the deployment • To linged Roads • To create water bloom • To spread fish deases
