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.
