* All Algaes are Autotrophs

* The Alga are called the Thallus because of lack of Vascular Tissue

* All Algaes are Eukaryotic, Except Blue Green Algae (Prokaryotic)

* The Biggest Single Cell Algae -Acetabularia, Used to Cytological Study

* Some Single Cell Alga - Chlamydomonas, Chlorella, Euglena

* Some Single Cell Thallus Structure Algae - Ulothrix, Spirogyra, Oedogonium

* Some Branched Thallus Algae - Cladophora, Pithophora, Bulbochaete

* False Branching Found in Scytonema

* Some Heterotrichous Thallus Alga - stigeoclonium, Fritschiella, coleochaete, Bulbochaete

* Some Epiphyte Alga - Oedogonium, Cladophora, Vaucheria

* Parasitic Alga - Cephaleuros, Rodochytrium, Phyllosiphon, Harviyella
                           - Cephaleuros Virescens - Affected Tea Leaf
                           - Cephaleuros Coffee - Affected Coffee Leaf

* Zoochlorellae is a Endozoic Algae - Growing inside the Hydra

* Algae With root, stem Structure - Caulerpa, Sargassum, Laminaria, Fucus, Macrocystis

* Fucus Algae is Called - Rock Weed

* The Largest Sea Weed (Algae) - Macrocystis ( 60M), Nereocystis (50M)

* Free Floating Algae - Phytoplankton - Eg. Chlamydomonas

* Spirogyra is Called - Water Silk or Pond Silk or Pond Scum

* Algae and Fungus Are called - Red Rust Of Tea

* Giant Algae - Laminaria - Growing 180 M

* Laminaria Fibre is called Lamina

* Algae cell wall is made up of Cellulose

* Chlorophyll - a Pigment is present in all Algae

* Starch is storage material of many Algae

* Three type of Pigments found in Algae - 1. Chlorophyll (a,b,c,d,e), Carotenoids, Biliproteins

* Water Soluble Biliproteins - Phycoerythrin - Rhodophyceae (Red Algae), Phycocyanin - Cyanophyceae (Blue Green Algae)

* Plastids - Chlamydomonas - Cup Shaped
                    Ulothrix - Incomplete Band Shaped
                    Zygnema - Star Shaped
                    Spirogyra - Ribbon Shaped
