At 40x magnification Stella will see organism 5mm.

At 100x magnification Stella will be able to see organism 2mm.

At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.

2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.
