2 For more awesome GSE and level resources, visit us at 1 In a photosynthesis experiment, a plant is left in bright sunlight for several hours. leaf is then removed from the plant and tested for starch, using iodine solution. The diagram shows the leaf from the plant that was used in the experiment. white area green area Which diagram shows the result of the experiment? key iodine solution turns blue / black iodine solution stays brown 2 Which substance, needed for protein synthesis, is carried into a leaf from the stem? carbon dioxide nitrate oxygen starch 3 Which two substances are the products of photosynthesis? carbon dioxide and glucose carbon dioxide and oxygen and carbon dioxide oxygen and glucose

What are the raw materials and the waste product of this process? raw materials carbon dioxide and chlorophyll carbon dioxide and oxygen and chlorophyll oxygen and waste product oxygen oxygen carbon dioxide carbon dioxide 6 plant with variegated leaves has the starch removed from its leaves by placing it in a dark cupboard for 48 hours. lack paper is then fixed on one leaf as shown and the plant is exposed to light. fter 24 hours, which part of the leaf contains starch? green region white region black paper on both sides of leaf

4 For more awesome GSE and level resources, visit us at 7 plant with striped leaves similar to the one below was kept in bright light for six hours. white stripe green stripe leaf was taken from the plant and the chlorophyll removed. It was then tested for starch using iodine solution. Which diagram shows the result of the test? yellow-brown white blue-black yellow-brown blue-black blue-black green green 8 pparatus was set up as shown. air to pump sodium hydroxide solution lime flask X plant black paper lime flask Y Sodium hydroxide removes carbon dioxide from the air. Lime goes cloudy if carbon dioxide is bubbled through it. What happens to the lime in flasks X and Y when the pump is switched on? flask X flask Y goes cloudy goes cloudy goes cloudy stays clear stays clear goes cloudy stays clear stays clear

The carbon dioxide content of the in each tube was measured at the start and again three hours later. In which tube would there be a decrease in carbon dioxide content? plant black polythene to keep out light light light snail

In which region is starch stored? 20 The diagram shows the apparatus used in an investigation to measure the rate of oxygen production during photosynthesis. gas measuring cylinder bright light beaker glass funnel aquatic plant The investigation was repeated several times and the average amount of gas collected was calculated. Which two factors must be kept constant during this investigation? the amount of in the beaker and the height of the measuring cylinder the size of aquatic plant and the amount of gas in the measuring cylinder the size of aquatic plant and the duration of exposure to light the size of the beaker and the funnel
