2. if a plant cell has a lower water potential than its surrounding environment and if pressure is equal to zero, is the cell hypertonic (in terms of solute concentration) or hypotonic to its environment? will the cell gain water or lose water?

Hypertonic

Explanation:

In the event that the potential for the plant cell to assimilate water is lower than the environment's capability to ingest water, at that point indeed, the plant cell is hypertonic.   Tonicity is truly alluding to the osmosis direction. In the event that the water will stream out of the cell, at that point its hypertonic.  In the event that the water will stream into the cell, at that point the cell is hypotonic.

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.
