Bacteria• Most are so small they
appear as little dots• Some larger ones form
designs and shapes• Once thought to be
algae because they performed photosynthesis

Euglenoids(type of algae)
• Flagella – whip like tail for movement
• Red eyespot to sense light used for energy
• Large numbers may turn ponds bright green

Volvox(green algae)
• Spherical colonies• Bright green cells• Colonies may have up
to 500 cells

Amoeba
• Unicellular protist• Surround and engulf prey• Free forming, can change
shape

Paramecium
• Small unicellular organism
• Swims and rotates slowly
• Covered by hair-like cilia• Feed on bacteria and
smaller microorganisms

Vorticella(type of ciliate)
• Bell shaped or cylindrical body
• Cilia• Attach to plants and
animals• Stalk can contract quickly

Rotifer
• Small mulitcelled animal• Red, light sensitive
eyespots• Use cilia to rotate food
into their mouth

Daphnia
• Crustacean (hardened shell)
• Water flea• Large antennae for
movement• Large eyes

Worm
• Flexible• Break down organic
material on bottom of ponds
• Movements vary by type of worm

Insect Larvae
• Not microscopic, can be seen with naked eye
• Usually transparent• Well developed nervous
system and circular system
