BIOLOGY 1407 EXAM 1 PROTISTS VERIFIED STUDY GUIDE
General Characteristics of Protists - Answers - Diverse in species and function and
include any eukaryote that is not a plant, animal, or fungus. Some photosynthesize,
some consume bacteria, many interact in a large number of symbioses, some are
pathogens, live in a multitude of ecosystems, play important role in biosphere, usually
unicellular but multicellular exceptions include brown algae (kelp), slime molds, etc. First
eukaryotes, most are small or microscopic. Extremely diverse assortment, found in
many habitats including anywhere there is moisture. Some reside in bodies of host
organisms, many live in pond water. Some autotrophic, some heterotrophic, some both.
Autotroph - Answers - Uses an inorganic source (carbon dioxide) as a carbon source to
make its own food; a "producer." Many autotrophs use light energy to synthesize sugars
(foods) in a process called photosynthesis.
Heterotroph - Answers - Eats autotrophs or other heterotrophs or their organic products
for food; a "consumer"
Parasite - Answers - Certain heterotrophs that derive their nutrition from a living host,
which is harmed by the interaction.
Mixotroph - Answers - Uses both photosynthetic and heterotrophy.
3 basic ways that protists can be grouped based on how they obtain food - Answers - 1.
Algae 2. Protozoa 3. Fungus-like Protists
Algae - Answers - Autotrophic protist, photosynthesize; similar to plants
Protozoa - Answers - Heterotrophic, similar to animals. Ingest bacteria and other
protists first, then digest and absorb the food with enzymes internally.
Proto= "first" and zoa comes from zoion= "animal"
Fungus-like Protists - Answers - Heterotrophic, similar to fungi, secrete enzymes
outside of organisms which digest organic molecules in surroundings first, then absorb
digested nutrients.
3 basic ways in which protists can be grouped based on locomotion structures -
Answers - 1. Flagellates 2. Amoeboids 3. Ciliates
Flagellates - Answers - Structure for locomotion is flagellum, a long whip like
appendage. Some are anaerobic.
