Question

A cell whose cytoplasm has a concentration of 0.02 molar glucose is placed in a test tube of water containing 0.02 molar glucose. Assuming that glucose is not actively transported into the cell, which of the following terms describes the tonicity of the external solution relative to the cytoplasm of the cell?

A) isotonic
B) hypertonic
C) hypotonic
D) flaccid
E) turgid

Answer 1

I think the correct answer from the choices listed above is option A. The term that describes the tonicity of the external solution relative to the cytoplasm of the cell would be isotonic. An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. Hope this helps. Have a nice day.
