1.<\/span> The diagram below shows the initial diameter of a potato disc.<\/span><\/span><\/p>\n

\"\"<\/a>The potato disc was placed in a high water concentration for one hour.<\/span><\/span><\/p>\n

Which of the diagrams shows correctly the change in the diameter of the potato disc?<\/span><\/span><\/p>\n

\u00a0<\/span><\/p>\n

\"\"<\/a>2.<\/span> Four cylinders of potato tissue were weighed and each was placed into a salt solution of different concentration. The cylinders were reweighed after one hour. <\/span><\/span><\/p>\n

The results are shown in the following table.
\n<\/span><\/span><\/p>\n

<\/a>\"\"<\/a>In which salt solution would most potato cells be plasmolysed?<\/span><\/span><\/p>\n

3.<\/span> Of what are the c<\/span>arrier molecules involved in the process of active transport made?<\/span><\/span><\/p>\n

4.<\/span> Red blood cells have a solute concentration of around 0.9%. Which of the following statements correctly describes the fate of these cells when immersed in a 1% salt solution?<\/span><\/p>\n

a.<\/span> The cells will burst <\/span><\/span>b.<\/span> The cells will shrink<\/span><\/span><\/strong><\/p>\n

c.<\/span> The cells will expand but not burst <\/span><\/span>d.<\/span> The cells will remain unaffected<\/span><\/span><\/strong><\/p>\n

5.<\/span> Which of the following describe passive transport?<\/span><\/span><\/p>\n

\"N5_Unt_1_Sht_8f\"<\/a><\/span><\/p>\n

6.\u00a0What are the correct labels for S and T in the diagram below?<\/span><\/p>\n

\"N5_Unt_1_Sht_8i\"<\/a><\/span><\/p>\n

\"N5_Unt_1_Sht_8j\"<\/a>
\n7.<\/span> <\/span>The diagram below shows Paramecium, <\/em><\/span>a single-celled organism which lives in water.<\/span><\/span><\/p>\n

\"N5_Unt_1_Sht_8k\"<\/a> <\/span>\u00a0<\/span><\/p>\n

a)<\/span> <\/span>The water concentration outside <\/span><\/span>the cell is <\/span>higher<\/span><\/span><\/strong> than the water concentration of the cytoplasm. This causes water to <\/span>enter<\/span><\/span> the cell constantly.<\/span><\/span><\/p>\n

i.<\/span> <\/span>What is the name for this movement of water? <\/span><\/span><\/p>\n

ii.<\/span> <\/span>From the information given, state whether Paramecium <\/em><\/span>is likely to live in fresh water or salt water. Explain your choice.<\/span><\/span><\/p>\n

b)<\/span> Paramecium <\/em>must get rid of excess water. Pure water is collected in the vacuoles by removing it from the cytoplasm. The vacuoles are emptied to the surrounding water as soon as they are full.<\/span><\/span><\/p>\n

i.<\/span> <\/span>What would happen to the <\/span>Paramecium <\/span><\/em>cell if the vacuoles stopped working properly? <\/span><\/span><\/p>\n

ii.<\/span> <\/span>The vacuoles are not filled by the diffusion of water. What evidence is there to support this statement?<\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
