In the space below, draw three plants cells: one that is turgid, one that is flaccid, and one that is plasmolyzed. Indicate with arrows the direction of the net movement of water across the cell membrane. Feel free to draw these in a notebook, then uploading a photo below. It’s also ok if you use some program like Paint.  2 Underneath each cell you drew above, label whether the plant that cell represents was placed in a hypertonic, hypotonic, or isotonic solution.  3 Design and describe an experiment using celery stalks to demonstrate how certain conditions will cause a loss or gain of turgor pressure. In order to follow the scientific method, your description should start with an observation and be followed by: a. a testable hypothesis, b. an outline of the experiment that will test the hypothesis, c. a description of the type of data that will be collected, and d. a possible conclusion that could likely be made after completing the experiment and analyzing the data.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
