Living vs Nonliving Cells Practice Test

Two samples are viewed under the same microscope magnification.

Sample 1 (thin slice of mushroom): many round compartments with boundaries are visible.

Sample 2 (foam packing material): many holes/air pockets are visible, but they are not enclosed by cell boundaries and do not form repeating cell units.

Which statement best uses evidence to distinguish living from nonliving here?

Two samples are viewed under the same light microscope at 400×.

Sample 1 (pond water drop): the view shows many small oval units, each surrounded by a thin boundary; some units have a darker spot inside.

Sample 2 (glass bead): the view shows one smooth, uniform piece with no repeating units or boundaries.

Based on evidence from the microscope views (cells), which sample is living?
