Please answer 6-8 Use the information and Fiqure 2 to answer questions 6-7. In the experiment below, a solution of glucose and starch was placed in dialysis tubing and incubated for 30 minutes in a beaker containing water and potassium iodide. A color change from cloudy white to dark blue in the dialysis tubing indicates A. The presence of sugar inside the beaker B. The diffusion of lodine into the tubing. C. The absence of sugar inside the beaker. D. The absence of starch inside the beaker. E. None of the above. 6. Figure 2 lodine solution Dialysis sac -Starch and glucose 7. The presence of sugar in the beaker solution indicates that the dialysits solution tubing is A. Impermeable to starch and sugar. B. Impermeable to starch. C. Permeable to starch. D. Permeable to sugar E. None of the above. 8. In a BIO 115 experiment, students put a stalk of kale in red dye solution to study the transport of water and nutrients looked at a slice of the kale under the microscope, they noticed that only certain parts in the cross section in plants. After 30 minutes, the students measured the distance the red dye had travelled in the kale. When the students showed the presence of the red dye. Which structure in the kale was responsible for the transport of the dye A. Phloem B. Xylem C. Stomata D. Chloroplasts Page 1 of 6

Explanation / Answer

6. A color change from white into blue indicates, the diffusion of iodine into the tubing. Hence, option “C” is correct.

7. The presence of sugar solution indicate that dialysis tube is imperable to starch. Hence option “B” is correct.

8. Xylem is the responsible for transporting water in the plants and is responsible for transporting dye. Hence, option “B” is correct.
