Protist Notes
Chapter 3 Book A
General Characteristics
 Eukaryotic
 Producers and Consumers
 Three Groups:
1. Fungus-like Protists
2. Plant-like Protists
3. Animal-like Protists
Fungus-like Protists
 Fungus-like protists are like fungi
because they obtain their food similarly:
 Consumer
 From dead organic matter
 Secretes digestive juices into food sources
and then absorbs nutrients.
2 Types of Fungus-like
Protists:
1. SLIME MOLDS
•
single-celled thin mass of slime,
• Colorful, shapeless
• Grow in cool, shady, moist places
Ex. Woods, fresh water
• Consume:
bacteria, yeast, decaying matter
• Reproduction—spore knobs
2 Types of Fungus-like
Protists:
2. Mold
• Consumer-decomposer and parasitic
• Grow in water, moist soil, in other
organisms
• Cause disease
ex. Potato famine
Plant-like Protists: ALGAE
 Producer—photosynthesize by using
chlorophyll
 Grows in water
 Multicellular = kelp, seaweed
anchored
 Unicellular = microscopic
floats
Plant—like Protists cont…
1. Microscopic: Phytoplankton
• food for other oceanic creatures
• produces the world’s main oxygen
supply
• 6 Phyla based on color and structure:

Pigment Structure Characteristics
Red
Chlorophyll

Red pigment allows it to grow in
deep waters because it is good at
absorbing light. Tropical. Short:1m.
Yellow-brown
Chlorophyll
Multi
Cool climates.
Long:60 m
Chlorophyll
Single and
Multi
Very diverse.
Chlorophyll
Single
Salt and fresh water.
Unusual shapes. Rigid cell walls.
Used in lots of daily products
Chlorophyll
Single primarily
DIverse. Salt water mostly.
2 flagella
