Question

1. properly set up your microscope to prepare for viewing the specimens.
2. carefully pick up the slide labeled \a\ and place it on the stage, being sure to use the stage clips.
3. bring the specimen into view on the low power objective using the coarse adjustment knob. then focus the image using the fine adjustment knob.

note your initial observations:

1. turn the revolving nosepiece to increase the magnification to the medium power objective. if needed, focus the image using the fine adjustment knob.

draw what you see in the space below:

do you believe this is a prokaryotic or eukaryotic cell? why?

if you believe it is eukaryotic, do you think it is an animal or plant cell? why?

is this organism unicellular or multicellular? why?

Explanation:

• Prokaryotic vs. Eukaryotic: Prokaryotic cells lack a nucleus and membrane - bound organelles. Eukaryotic cells have a nucleus and membrane - bound organelles. The cell in the image (assuming it has a nucleus which is a key feature of eukaryotes) is likely eukaryotic.
• Animal vs. Plant: Plant cells have cell walls and chloroplasts (if they are photosynthetic). Animal cells do not have cell walls. If the cell in the image has a cell wall (a common feature in plant cells), it is a plant cell.
• Unicellular vs. Multicellular: Unicellular organisms consist of a single cell. Multicellular organisms have multiple cells. If the observed specimen is made up of many cells (as in a tissue - like structure which is common in plant tissues), it is multicellular.

Answer:

• Do you believe this is a prokaryotic or eukaryotic cell? Eukaryotic. Why? (Assuming the cell has a nucleus, which is a defining feature of eukaryotic cells).
• If you believe it is eukaryotic, do you think it is an animal or plant cell? Plant. Why? (Assuming the cell has a cell wall, a characteristic of plant cells).
• Is this organism unicellular or multicellular? Multicellular. Why? (Assuming the observed structure is a collection of cells, indicating a multicellular organism).
