### Outside the Nucleus

Do Now:

Use your lab handout to answer. A student measures the low power field of view of their microscope to be 6.0 mm.

A: What is the medium power F.O.V.?

B: if about 20 animal cells fit in the medium power field of view, how big is each cell?

Medium power FOV
• Medium FOV = (low power diameter)(low power objective) / (medium power objective)
• = (6.0 mm)(4) / (10) = 2.4 mm
How big are the cells?
• (Medium FOV) / (# cells) x 1000
• = 2.4 mm / 20 x 1,000 µm / mm = 120 µm

Label the cell membrane (aka plasma membrane),

nucleus, and nucleolus on your diagram
