Observe the 2 sets of plates from the osmotic pressure experiment and record the results below.

Plate	Escherichia coli	Staphylococcus aureus	Aspergillus niger
Control	+++	+++	+++
5% NaCl
10% NaCl
15% NaCl
5% glucose
10% glucose
25% glucose

+ = Scant growth
++ = Moderate growth
+++ = Abundant growth
- = No growth
