Answer:
Explanation:
A way you can use celery stalks to demonstrate the conditions with loss or gain of turgor pressure, is by setting us the same situation with water. I. You could possibly make a chart with how the celery could change. II. Testing the different out comes of the celery changing and what it has done and if it matches the hypothesis. III. The type of data you could conduct would be is seeing the height, length, and width. As wellas trying to see how much celery would soak up. IV. A possible conclusion of that experiment would be that the celery stalks would all expand expect for the one not in any water and it all would possibly start to grow into more than one celery and sprout.

Turgor pressure is the pressure due to fluid in a cell, that provides a force making the plasma membrane to push upon the cell wall
The responses and reasons for the experiment demonstrating the conditions by which turgor pressure is lost or gained are as follows:
Observation: Cut celery placed in water are fresher and are not as wilted than cut celery placed on a table without water, or placed in a salt solution
(i) A testable hypothesis is given as follows;
Hypothesis: The turgor pressure is gained by increasing the hypotonicity of the water that the celery stalks is placed into
(ii) An outline of an experiment to test the hypothesis is presented as follows;
- Procure three celery ticks and three beakers that can contain a stick each
- Place 100 mL fresh water from the tap into one of the beaker, 100 mL of 5% salt solution into the second and 100 mL 10% salt solution into the third beaker, and label the beakers
- Measure and record the mass and sizes of celery stalk lengths cut to 5 cm length and identically sized, after which they are placed one each into each beaker
- Take a picture of the sticks in the containers that shows the sizes of the sticks, and also write a note describing each stick in the lab notebook
- Place the containers into the fridge overnight
- Measure and record the parameters of the sticks removed from the fridge and take a picture of the sticks with a ruler by the side of the container to show the size of the sticks
- Record the observation
(iii) A description of the type of data that will be collected include, the width, mass and length of each celery
(iv) A possible conclusion that could likely be made after completing the experiment is that the gain in turgor pressure is directly related to the hypotonicity of the solution the stick of celery stalk is placed
