Ex. 4 Preparing a Wet Mount and Observing Microscopic Organisms
Algae • Kingdom – Protista • Eukaryotic, single celled or multucellular organisms with a cell wall, live in water and are photosynthetic • Found in fresh water, sea water and salt water (Great Salt Lake)
Prepared Algae Slides • 1. Spirogyra • 2. Ulothrix • 3. Oedogonium • 4. Chlamydomonas • 5. Volvox
Spirogyra • Filamentous green algae commonly found in fresh water • Chloroplasts are spirally arranged
Ulothrix • Filamentous green algae found in fresh and marine water • Thrive in low temps of spring and winter
Oedogonium • Filamentous green algae found in fresh water
Pond Water (Hay Infusion) • Observe living microscopic organisms • Check for life characteristics • True Motility vs. Brownian Movement • Phototaxis – positive or negative • Chemotaxis – positive or negative • Aerotaxis – positive or negative
