1. Lesson 11 Notes
Protists

2. What we will look at:
Amoeba
Paramecium
Euglena
Volvox

3. Objectives Make a list of things you already know about microbes.
Observe four species of living microorganisms called protists and identify their animal-like and plant-like characteristics.
Observe, draw, and estimate the length of four protists.
Create a cartoon using an Amoeba, Euglena, or Paramecium as the main character.
Read about the importance of microorganisms in history.
Read about the kingdom Monera and its significance to humans.

4. Protists all have: Cytoplasm Nucleus
Reproduce asexually by cell division
Vacuoles
Food and water storage

5. B. Amoeboids PSEUDOPEDIA (false feet) .25 mm – 25 mm
For movement & trapping of food
.25 mm – 25 mm
Thin cell membranes
Ectoplasm: excrete wastes, absorb O2, eliminate CO2
Endoplasm: within cytoplasm
Live on aquatic plants, moist ground, or as parasites on animals
Contractile vacuole: eliminates excess water

8. C. Ciliates: Paramecium
Single-celled
Slipper-shaped
Cilia: tiny hairs for movement and trapping of food
Size of bacteria – 2 mm
Oral groove: opening for food & bacteria
Contractile vacuole

11. D. Flagellates: Euglena
Single-celled
15 – 500 micrometers
Contain nucleus, chloroplast, contractile vacuole, stigma (eyespot), one or more flagella
Pellicle: wall allowing for change in shape
Also absorption of food
photosynthesis

15. E. Volvox Pond alga Spherical colonies 1000-3000 cells per Volvox
Flagella
1 mm in diameter (width)
Found in ponds, puddles
Absorb food through cell surface
Photosynthesis
