Spirogyra-Member of Chlorophyta (green algae)-Have Spiral Chloroplast-Pyrenoids: structures along the chloroplast that store starch-Have a distinct cell wall

Oedogonium-genus of freshwater alga, found in pond cultures-Netlike chloroplasts that extend around inner wall of cells-Pyrenoids: structures along the chloroplast that store starch-Oogoia: Structure along filaments where female gametes are formed

Volvox-Swimming spherical colony of several thousand cells-loose coordination between cells, but each is photosynthetic and self-sustaining.-form daughter colonies from cells specialized for reproduction

Chlamydomonas-one of the simplest chlorophytes-unicellular and bi-flagellated.

Laminaria sp.-Member of Phaeophyta (brown algae), restricted to ocean-commonly referred to as seaweed.

Diatoms Pennate and Centrate-unicellular algae with a wall of silica-microscopic photosynthesizers, primary food source for most marine food chains-contain abundant carotenoids and fucoxanthin (pigments)-Found in ocean, freshwater, and soil-Frustule: silicon impregnated case-Raphe: a longitudinal line found on the frustule-Pennate: bilaterally symmetrical-Centrate: radially symmetrical-have many uses including grinding, polishing, filtering, and providing information for geologists
