Cytoplasm in a plant cell will shrink if the cell is
1. placed in a concentrated salt solution
2. kept warm and moist and in medium light
3. placed in distilled water
4. exposed to a different concentration of nitrogen gas

1 is the answer

Explanation:

Well, this is a tricky question indeed. Theoritically speaking, it's true that a cytoplasm will shrink because the entropy of the system will tend to balance the salt concentration between the two sides of the membrane. This process is called osmosis and sooner or later, both sides will be balanced in terms of salt concentration. However, remember that plants (actually organisms) have the homeostasis system which does not let these things happen.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
