50th Day of School
Learning goal (7.L.1): I will be able to describe
the characteristics of Euglena.
Due Today: Characteristics of Life foldable
Evening Assignment: Finish Euglena part of
chart
On the slip of paper, write the eight
characteristics of life shared by all living
things?
http://vimeo.com/15407847
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
Flagella
Cilia
Pseudopod
Cytoplasm
Vacuole
Cell membrane
Mitochondria
Chloroplasts
Life Functions of single-celled Organisms
Make a Characteristics of Life foldable

1) Explain the heading
in your own words
2) Give an example of a

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
carries oxygen
Cell
Autotroph
Photosynthesis
Heterotroph
4 Vocabulary Flashcards
Example
Outside Flap
Inside Flaps
All life is
Living things are organized into
structures (cells, organelles,
tissues, etc.) that perform life
functions.
_____________________
For example, humans are made
up of many cells, tissues, organs,
and organ systems that help us
use energy, remove waste,
respond to the environment, and
reproduce.
Organized
Characteristics of Life
Foldable
• Organization: Singlecelled, flagellate algae
with a red eye spot
• Respond to
Environment: Single
flagella allows it to move
toward food or away from
predators
• Energy Use: Autotrophmakes it’s own food like
plants; Heterotroph- eats
other organism
• Evolve/Adapt: When
water is scarce, forms a
cyst
Euglena
•
•
•
•
•
Autotroph (makes it’s own food)
Sense light using red eyespot
Move toward light with flagella
Chloroplasts -> photosynthesis
Can also feed heterotrophically
by engulfing food
• Waste is removed by the vacuole
Euglena Feeding & Waste
removal
• Asexual reproduction only
• Through binary fission
• One organism splits into
two genetically identical
organisms
