Questions p. 15
1. 4 characteristics of living things:
organization
growth and development
response to environment
reproduction
2. The microscope changed human understanding of life by
allowing people to see cells. Before the microscope humans
did not realize that life could be so small.
3. Cell Theory:
every living thing is made of one or more cells
cells carry out the functions needed to support life
cells come only from other living cells
4. The cell theory is widely accepted and explains observations
of nature, and is supported by evidence such as Pasteur’s
experiments.
5.
Unicellular
One cell
Multicellular
Many cells
Cannot be seen
directly
Easier to see
simple
complex
Both
Need energy,
materials and living
space
Have the ability to
reproduce, grow &
develop & sense
their environment
Made up of cells &
come only from
other cells
6. In Pasteur’s experiment, bacteria did not grow
spontaneously. They came from the environment, which
indicates that cells come from other cells.
Discussion Questions from video
1. How does the actual size of the unicellular organisms you are
looking at compare with that of a familiar object? like a grain of
sand; pixels in a computer
2. What do these unicellular organisms have in common? All can
reproduce. How do they differ from one another? size, how they
acquire their food, structures
3. What characteristics do these unicellular organisms share with
multicellular organisms such as insects, birds, squirrels, and humans?
All are made up of cells and bodies are organized. All have the
ability to reproduce. All have the ability to grow and develop.
All have the ability to respond to the environment.
4. How do unicellular organisms get their nourishment? as either
autotrophs (make their own food) or heterotroph How do they
get water? How do they get oxygen? How do they get rid of wastes?
Needs of life:
1. energy (from the Sun & food)
2. materials (carbon dioxide, nitrogen, oxygen and water)
3. living space (All living organisms live near or in the water, and get
materials from their surroundings.)
