Journal Entry #15: Perform the following procedures to observe osmosis and plasmolysis in a plant cell.

PLASMOLYSIS IN PLANT CELLS PROCEDURE:

1. Make a wet mount of the red onion epidermis.

2. Examine under medium power (10X). When you have a clear view of several cells, switch to high power (40X). Make a colored drawing, properly labeled in the first circle on the data sheet (Fig. 2). Label the nucleus, cell wall, and cell membrane.

2. Draw the water out of your specimen by lifting the cover slip and placing a small piece of paper towel along the edge of the slide. The paper should draw out the water. Place two drops of salt solution on your specimen.

4. Observe the effects of the salt solution on the onion cells. Make a properly labeled, colored drawing of the cells' appearance in the second circle on the data sheet (fig. 3).

5. Replace the sodium chloride solution with distilled water in the same way that the salt solution was added. Make a properly labeled, colored drawing of the cells' appearance in the third circle on the data sheet (Fig. 4).

CONCLUSION QUESTIONS:

1. Why do grocery store owners spray fresh fruits and vegetables with water?

2. Roads are sometimes salted to melt ice. What does this do to plants around the roadside and why?

3. If a shipwrecked crew drinks sea water, they will probably die.

Why?

4. If a bowl of fresh strawberries is sprinkled with sugar, a few minutes later the berries will be covered with juice. Why?

Science Inquiry and Application

During the years of grades 9 through 12, all students must use the following scientific processes with appropriate laboratory safety techniques to construct their knowledge and understanding in all science content areas:

• Identify questions and concepts that guide scientific investigations;

• Design and conduct scientific investigations;

• Use technology and mathematics to improve investigations and communications;

• Formulate and revise explanations and models using logic and evidence (critical thinking);

• Recognize and analyze explanations and models; and

• Communicate and support a scientific argument.

Cell function

• Cellular processes

o Characteristics of life regulated by cellular processes o Photosynthesis, chemosynthesis, cellular respiration o Cell division and differentiation
