A

Cells are loosely associated (colonial forms)

17
Q

Brown Algae

A

Commonly called seaweed or kelp

18
Q

Red Algae

A
  • Smaller and more delicate than brown algae
  • Grow in shallow waters
19
Q

Diatoms

A
  • Cell Wall: in two sections woth larger one fitting over the smaller with a “Shoebox lid” fit; c.w. inpregnated with silica
  • “Live in glass house”
  • cell walls do not decompose: Diatomaceous Earth- used in filters and insecticides
  • Photosynthetic and extremely abundant
20
Q

Dinoflagellates

A
  • Have 2 flagells; one free and one wrapped around
  • Spin like a top
  • Can cause “Red Tide”
  • Toxins from red tide can cause widespread fish kills
  • Can cause paralysis in humans who eat shellfish that consume these protists
21
Q

Heterotrophic Protists

A
  1. Injest food by forming food vacuoles
  2. Amoeba: Pseudopods
  3. Paramecium: “Slipper shaped”; ciliated
22
Q

Slime Molds

A
  1. Once classified as fungi
  2. Unlike fungi, they phagocytize their food like amoeboids
  3. Types:
    1. Cellular Slime Molds
    2. Plasmodium
23
Q

A

Exists as indiviuals

24
