1. Protist / Algae Live Specimens Lab

2. Nostoc Blue-green alga. Filaments are called “trichomes”.
Form slimy gelatinous colonies with many trichomes encapsulated within a sheath.
No nucleus visible, but chromatin granules seen.
Large cells (heterocysts) visible and are breakage points from which new colonies form.

3. Spirogyra Green alga. Filamentous. Spiral – shaped chloroplast.
More than 400 species in the world.
Conjugation (sexual reproduction) seen as a ladder-like structure.

4. Ulothrix (Spore-like)
Filamentous green algae
Fresh and Marine Environment
Eukaryotic
Unicellular
Autotrophic
Vegetative/Sexual or Asexual Reproduction

Pest organism

6. Euglena Unicellular protist. Freshwater. One flagellum is visible.
Contains chloroplast and can carry out photosynthesis.
Flexible body that can change shape.
Divides by binary fission.

7. Paramecium Unicellular protist. Freshwater pond.
Reproduces both asexually and sexually via conjugation.
Cilia for movement.
Macronucleus and one or more micronuclei.
More than 80,000 species identified.

8. Blepharisma Unicellular protist. Ciliate. Pink colored pigment.

Conjugation occurs.

9. Amoeba Unicellular protist. Moves via extending pseudopods.
Feeds by extending pseudopods around food and engulfing it (phagocytosis).
“Shape shifter”.
Reproduces via binary fission.

10. Eudorina Colonial flagellate.
16 – 64 spherical cells, each with 2 flagella.
Contain chloroplasts and can carry out photosynthesis.
Green alga.
