Part 2: The World of Protists
What Makes Protists Special?
Protists are _____________________________________________
 ________________________________________________________
Protists are _____________________________________________
 many are ______________________________/ others are __________________________
 some _______________________________________/ others ______________________________
Others are _____________________________________________
 some are ________________________/ others __________________________
Scientists believe they provide __________________ of the oxygen in our current atmosphere
What Do Protists Share in Common?
They are all _________________________ (which means they have a ________________)
They have a ______________________________________, but most have no cell wall
Most are __________________, but some are ______________________
Protists are so diverse that they are more different than similar!

(example___________________________________)
(example_________________________________)
Parts of the cell (organelles)? See chart on p. 74 of text for definitions of new terms
Nucleus(examples from part 3 with a nucleus _____________________________________________________________________)
Cytoplasm(examples from part 3 with cytoplasm _____________________________________________________________________)
Cell Membrane(examples from part 3 with a cell membrane _______________________________________________________________)
Chloroplast(examples from part 3 with chloroplasts __________________________________________________________________)
Vacuole (use definition for large central vacuole)(examples from part 3 with a vacuole _____________________________________________________________________)
How does it eat (get energy)? Definitions are provided
Autotrophs- organisms that make their own food using sunlight (contain chloroplasts)
(examples from part 3 that is an autotroph _________________________________________________________________)
-Eyespot- an organelle that detects light and allows some protists to find light for energy
(examples from part 3 that has an eyespot__________________________________________________________________)
Heterotrophs-
organisms that need to eat outside energy sources (can not make own food)
(examples from part 3 that is a heterotroph ________________________________________________________________)
-Oral Groove- an organelle that gathers food and take it into the cell (like a mouth)
(examples of from part 3 with an oral groove _______________________________________________________________)
Autotrophs that act like heterotrophs- organisms that can make food, but also eat food or have
more “animal-like” qualities
(____euglena________)
