Questions and Answers
How is the amoeba an example of an organism?
An amoeba is able to fit all characteristics of life, which include reproduction, organization, growth, response, homeostasis, and metabolism.
How would you classify an amoeba: animal-like, plant-like, or fungus-like? Why?
Animal-like
Research how amoeba reproduces and summarize your findings.
Amoebas reproduce via binary fission.

Euglena contains chloroplasts. When light is limited, they can eat particles to obtain energy. Are these organisms classified as heterotrophs or autotrophs?

Euglena are not the only organisms that have a flagellum. Zooflagellates are protozoa that also have flagella. Although euglena and zooflagellates move by flagella, why are these organisms classified differently?

You place millions of euglena into a container and place it by the window. The entire container is a bright green color as the euglena swim freely. You cover half the container, blocking out the sunlight. At the end of the day, you return to the container and find that all the euglena are now on the uncovered side. Explain why this happened.

Study Notes
Amoeba as an Organism
- An amoeba meets all characteristics of life: reproduction, organization, growth, response to stimuli, homeostasis, and metabolism.
- Classification relies on an organism’s ability to display these essential life functions.
Classification of Amoeba
- Amoeba is classified as animal-like due to its purposeful movement and feeding habits.
- Lacks chloroplasts, preventing photosynthesis; does not reproduce through spores like fungi.
Reproduction of Amoeba
- Amoebas reproduce via binary fission, where a single parent cell divides to produce two daughter cells.
Paramecium as a Living Organism
- A paramecium exhibits all characteristics of life, responding effectively to its environment and actively obtaining food.
- Capable of locomotion and reproduction, distinguishing it as a living entity.
Survival Structures of Paramecium
- Paramecium regulates water balance to maintain cellular equilibrium, preventing shrinkage or bursting.
- Utilizes organelles to trap and digest prey within vacuoles, crucial for obtaining nutrients.
Classification of Paramecium
- Paramecium is classified as animal-like due to its predatory behavior and lack of chloroplasts.
- Reproductive methods differ from plant and fungal classifications.
Complexity of Paramecium
- Considered a complex organism due to its specialized digestive structures, including the oral groove lined with cilia.
- The presence of a vacuole distinguishes it from simple organisms that only perform endocytosis.
Euglena's Protist Group
- Euglena belongs to the group of protists known as algae.
Nutritional Classification of Euglena
- Euglena is classified as both autotrophic (creates food through photosynthesis) and heterotrophic (consumes external organisms when light is insufficient).
Distinction Between Euglena and Zooflagellates
- Euglena has the capability of photosynthesis due to the presence of chloroplasts, unlike zooflagellates which cannot perform this process.
Unique Organelles in Euglena
- Distinguishing organelles not found in zooflagellates include stigma (eyespot) and chloroplasts.
Euglena's Movement Toward Sunlight
- Euglena migrated to the illuminated side of a container as it recognized through its eyespot that insufficient sunlight was available for photosynthesis in the shaded area.
- The ability to move towards sunlight enables continued efficient energy production.
Labeled Diagrams
- Labeled diagrams of Paramecium, Euglena, and Amoeba may include anatomical structures to provide visual context.
Zygomycota Reproduction
- Specific reproductive methods utilized by Zygomycota need further research to provide detailed notes.
