51st Day of School
Learning goal (7.L.1): I will be able to describe the
life characteristics of Amoeba and Paramecium.
Due Today: Euglena part of chart & flashcards
Evening Assignment: Finish
Amoeba/Paramecium part of chart
Explain why I have written Euglena using
the color scheme? How do the colors relate
to how it gets energy?
Do Now
What characteristics do all living
things share?
All living things…
• Are organized (cells,
structures)
• Reproduce (pass on genetic
material)
• Use energy
• Grow & develop
• Remove waste
• Regulate Internal Conditions
(homeostasis)
• Respond to the environment
• Evolve and Adapt

Characteristics of Life
• As you watch note what
role each of the following
plays in the life of
unicellular organisms:
•

Nucleus

Definition: A cell is
the basic unit of life
that is able to perform
basic life functions.
Examples:
Euglena: single-celled
organism
Red blood cell: cell in
human body that
carried oxygen
Cell
5. chloroplast
Autotroph
6. flagella
Photosynthesis 7. cilia
Heterotroph 8. pseudopod
8 Vocabulary Flashcards
• Organization: Singlecelled, shapeless & has
pseudopods
• Respond to Environment:
Cytoplasmic streaming
allows it to move toward
food or away from predators
• Energy Use: Heterotrophicengulfs food with
pseudopods
• Evolve/Adapt: Can become
dormant
Amoeba
• Heterotroph (eats bacteria,
algae & other protozoa
• Surrounds food and engulfs it
with pseudopods
• Moves by cytoplasmic
streaming
• Can change shape
• Waste is removed by the
vacuole
Amoeba Feeding & Waste
removal
• Asexual reproduction only
• Through binary fission
• One organism splits into
two genetically identical
organisms
Amoeba Reproduction
• Organization: Single-celled,
shaped like a shoe sole & has
cilia
• Respond to Environment:
Cilia allows it to move toward
food or away from predators
• Energy Use: Heterotrophicuses cilia to sweep food into
the oral groove
• Evolve/Adapt: Stiff elastic
membrane gives it shape and is
covered in cilia that allow it to
spiral through water
Paramecium
• Heterotroph (eats bacteria,
algae & yeast)
• Cilia sweeps food into oral
groove
• Moves by cilia
• Has 2 nuclei: one large &
one small
• Waste is removed by the
vacuole
Paramecium Feeding &
Waste removal
• Asexual reproduction
Through binary fission
• One organism splits into
two genetically identical
organisms
• Sexual reproduction occurs
if there is environmental
stress or overcrowding.
Example of how
paramecium
response to the
environment and
evolve/adapt
