Kingdom Protista
SWBAT list the prime characteristics of
organisms in the kingdoms Protista; describe
three ways that protists may move; list two
general ways that protists obtain energy;
explain fragmentation and conjugation in
protists
Kingdom Protista

What common characteristics do
organisms in kingdom Protista share?
Have a nucleus (eukaroytic)
 Unicellular

Two Groups of Protists

What are the two general types of
organisms in this kingdom?

Protozoa
Animal like protists
 Move on their own
 Capture food


Algae
Plant like protists
 Perform photosynthesis
 Cannot move themselves

Structures of Protists

Colony


A group of unicellular protists living together,
though capable of living on their own
How is a colony different from tissue?

Tissue cells cannot live on their own.
Tissue is found in multicellular organisms
Movement of Protists

What are the three general ways protists
can move themselves?

Flagella


Cilia


Whipped back and forth to propel the cell
Move like oars to propel the cell
Pseudopodia

A buldge forms in the cytoplasm and works as
an anchor for the cell to pull itself forward
Nutrition in Protists

What are two general ways that protists
get energy?
Eat other protists, bacteria, or debris
 Use energy from the sun to make their own
food


Invagination

An infolding of the cell that creates a food
vacuole
The Importance of Protists

Plankton


How are protists (specifically plankton)
important for life?


Microscopic organisms that float or drift near the
ocean’s surface
Food source for most of the ocean’s animals
What are some harmful effects that protists
have?

Cause diseases



Malaria
African sleeping sickness
Dinoflagellates - toxic
Reproduction in Protists

What is fragmentation?
A protists creates threads called filaments
which when broken result in 2 colonies.
 Breaks into two


What is conjugation?

Filaments line up and grow between
protists. These tubes join the cells and
allow genetic material to be exchanged
