How did you set up your microscope and microscope slide?
- Microscope - We gently carry the microscope to our station. We didn't have any light source but we had a mirror so, we had to get a light box to be our light source. Then after that we turn it on and turn the light directly to the mirror.
- Microscope slide - We place our specimen in the middle of a clean slide. We ensured the our specimen is laying flat and not folded over on itself. We added 2 to 3 drops of the stain solution. Plant cells are commonly stained with iodine, whereas animal cells are commonly stained with methylene blue. Both of these solution will stain the nucleus. We gently put the coverslip on a 45 angle and slowly putting it down.

What did you observe down the microscope/something that was discovered by a microscope.
- A Dutch father-son team named Hans and Zacharias Janssen invented the first so-called compound microscope in the late 16th century when they discovered that, if they put a lens at the top and bottom of a tube and looked through it, objects on the other end became magnified.
Plant cell
- The cells that we saw was a rectangular shape as the teacher say it was.
- Underneath the microscope we saw the Nucleus, Large Vacuole, and etc.
Animal Cell
- Our microscope didn't have enough magnification so, we only saw the part of a leg Moth.

What are key similarities and differences between plant and animal cells.
- Both animal and plant cell has a cell membrane, cytoplasm, nucleus, and a mitochondria.
Similarity
- Cell Membrane
- Cytoplasm
- Nucleus
- Mitochondria
-------------------------------------------------------------------------------------------------------------
- A plant cell has extra organelles - including, large vacuole, cell wall, and chloroplast.
Difference
- Large Vacoule
- Cell wall
- Chloroplast
