, Biology Gizmo - Cell Types
Knowledge Questions:
1. How do you know if something is alive? Describe some of the characteristics of living
things.
In order to recognize if something is alive it must breathe and reproduce excrete. Living
things require energy as well as water
2. Humans, plants and mushrooms are all alive. What do these organisms have in
common?
What they all have in common is that they all have cells, they grow and develop, and
they all use energy.
Gizmo Warm-up:
In the Cell Types Gizmo, you will use a light microscope to compare and contrast different samples. On
the LANDSCAPE tab, click on the Elodea leaf. (Turn on Show all samples if you can’t find it.) Switch to
the MICROSCOPE tab to observe the sample as it would appear under the microscope. By default, this
microscope is using 40x magnification.
1. Drag the Coarse focus slider until the sample is focused as well as possible. Then,
improve the focus with the Fine focus slider. What do you see?
I see almost hexagonal compact plant cells.
2. Select the 400x magnification. If necessary, adjust the fine focus. Now, what do you
see?
I see a more clear visual of an individual plant cell and I'm now able to identify the
nucleus.
The individual chambers you see are cells, the smallest functional unit of an organism.
