Kingdom Protista
Introduction
 Kingdom Protista contains __ __ __ __ __ __ __ __ __ __ __ __ __ __. This is like
Kingdom Monera.
 What is the difference between Kingdom Monera and Kingdom Protista?
... This fact adds a level of complexity to the organisms in kingdom Protista that does not
exist in Kingdom Monera.
... Discuss how is it more complex?
Because of the complexity, we cannot study a “typical” organism from Kingdom Protista (in the way
that we studied bacterium in Kingdom Monera). We will look at the classification system for this
kingdom and then look at the organisms within each major phylum.
Classification in Kingdom Protista
Consider Figure 3.1...
Subkingdom 1: Protozoa
- What is the main difference between Subkingdom Protozoa and Algae?
- Another quality that separates them from algae is the fact that most protozoa are heterotrophic,
while most algae are autotrophic.
Phylum 1: Phylum Sarcodina.
 KEY: Phylum within Subkingdom 1 can be distingushed by the way they MOVE.
(Locomotion).
 Have no standard body shape... they are enclosed in a flexible plasma membrane that allows
them to change shape at will.
 When resting, they are usually somewhat spherical. However, when they wish to move, they
form extensions of their bodies called pseudopods or “__ __ __ __ __ __ __ __ __.”
Pseudopod:
Draw a picture of a member of Phylum Sarcodina:
Tell your partner about the role of the following organelles in this phylum:
 Nucleus:
 Vacuole:
 Cytoplasm...
- Ectoplasm:
- Endoplasm:
Explain to your partner the way amoeba eat and move. (Nutrition and locomotion).
Phylum 2: Phylum Mastigophora
At Home...
 One of the features of organisms in phylum mastigophora is flagellum.
 Flagellum:



 Although most flagellates use their flagellum to swim freely in water, some use it
to attach themselves to a sold object.
Members of this phylum vary significantly in shape.
Genus Euglena provide an interesting example of organisms from phylum Mastigophora.
Members of this genus have the ability to ....
Despite this fact, we do not necessarily consider them autotrophic because...
 Thus members of Genus Euglena are both...
 Even when there is plenty of light for photosynthesis, euglenas still tend to...
 When their surroundings become dim, their photosynthesis shuts down, and they
become completely _____________________. In fact, if their environment stays ______
for several day or more, the euglenas’ photosynthetic capability ___________________.
After that happens, they can _____________ produce their own food again, regardless of
how bright their surroundings might later become.
In Class (Next Lesson)...
Draw Figure 3.4...
Tell your partner about the role of the following organelles in this phylum:
 Contractile vacuoles: help expel excess ______ in order to reduce pressure inside the cell.
 Nucleus: Holds main ______ and controls both reproduction and metabolism.
 Pellicle
 Chloroplast:
 Chlorophyll:
 Eyespot:
Complete: Euglenas reproduce only ____________________. Under ideal conditions, a single
euglena can reproduce __________ a day.
