Euglena

Are euglena considered a heterotroph, autotroph, or decomposer?

• Autotrophic - meaning they can create their own food by using chloroplasts.
• Heterotrophic - meaning they have to go search for their food.
• Decomposer - meaning they eat off of dead, rotting matter.

What special way do euglena eat?

• Euglena use a flagellum to sweep food into a gullet-like mouth called an oral groove.
• Euglena use the process of photosynthesis which allows a Euglena to convert light energy into sugars for the organism.
• Euglena engulf food with pseudopods which allows a euglena to be heterotrophic

A contractile vacuole is used by a Euglena to 

• make their own food by the process of photosynthesis.
• secrete enzymes for digestion within the food vacuole.
• excrete excess water out of the cell
• produce antibodies to defend the cell from predators.

How does a euglena move?

• Cilia - many tiny hair-like structures that allow the euglena to move around its watery environment.
• Flagella - a whip-like structure that allows the euglena to move around its watery environment.
• pseudopods - aka false foot, euglena use cytoplasmic streaming which creates pseudopods to move around.

What are the ways within which microbiologists classify protists?

• Microbiologists classify protists by the way they look. Some of them are green in color, while others are clear.
• Microbiologist classify protists by observing their method of obtaining energy.
• Microbiologists classify protists by observing how they move. Some protists use cilia to move, while some other use cytoplasmic streaming or flagellum.
• Microbiologists classify protists by observing how they move, and the protists method of obtaining energy.

The ____ is a producer that uses light to make food.  It also uses it _____ to move toward light.

• amoeba, pseudopods
• paramecium, flagellum
• euglena, cilia
• euglena, flagellum
