1 Introduction to Lab Ex. Photosynthetic Microbes

2 Introduction to Lab 3: Ex. Photosynthetic Microbes
Microbes that are capable of photosynthesis Found in 2 groups: Protista –Algae; Monera - Cyanobacteria Organisms will be studied using stained slides and wet mounts. Specific organisms to be studied in the lab: Algae: Spirogyra Hydrodictyon Cyanobacteria: Oscillatoria

3 Spirogyra: (stained slide)
Characteristic features: filamentous with spiral chloroplast, sexual reproduction (through conjugation)

4 Hydrodictyon (water net) (stained slide)
Characteristic features: colonial form with individual cells arranged in benzene ring patterns)

5 Oscillatoria (wet mount)
Characteristic feature: filamentous form with oscillating tips; (shows gliding/creeping motility) prokaryotic.
