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.
Drag the Coarse focus slider until the sample is focused as well as possible. Then, improve the focus with the Fine focus slider. Select the 400x magnification. If necessary, adjust the fine focus. The individual chambers you see are cells, the smallest functional unit of an organism. Click on the show labels button.
State four structures that are found in an elodea leaf.
According to the microscope image, are elodea eukaryotic or prokaryotic cells?
State 3 organelles you see in the mouse skin.
State 3 organelles you see in the fly muscle
State 3 organelles you see in the maple leaf
State 3 organelles you see in the protista
State 3 organelles you see in the fungi
What do all of these samples have in common?
What organelles are present in E.coli?
What organelle is missing from E.coli?
What type of cell are E.coli?
Compare: Look at the Sand/silt sample under the microscope.Turn on Show labels. Does sand//silt have any internal structures?
Do you think sand is alive?

Marcus says all cells have the same structures, while Joelle says that some cells have different structures. After collecting evidence, do you agree with Joelle or Marcus? Why? Share your evidence to support your reasoning. You need at least 2 pieces of evidence.
