  6. It is believed that nature has the best sensors to detect climate change. Algae are said to be one. All algae use carbon dioxide but, while some lock up this gas in their calcified skeletons, others do not do so. other groups of algae produce compounds such as dimethyl sulphonioproprionate that can become climatically active. To understand this, one needs to be able to differentiate the algal types and count them using equipment that is precise and cheap enough so that very many can be used. To that end, Southampton University and the School of Electronics and Computer Science are developing a sensor which, when dropped into the sea, can record information about the types and quantities of algae present. This provides vital information for specialists in climate change


  7. Algae flow through the device one at a time at a high speed. When the device shines light at the algae, they respond by emitting light at different wavelengths. allowing them to be characterized. The device records data about such properties of algae which tells us about the size of particles and the types of membranes. Algae are now known to influence the climate in various ways. Much of the existing progress made by oceanographers has been based on studying satellite images in colour. The sea can have many different colours and what one sees depends not only on light and weather conditions but also on what plant life the water contains. Colour measurements have become an important tool for studying plant life in the oceans. Calculating the amount of chlorophyll from measurements of water colour is one of the successes of optical oceanography


  8. Q. 1 Consider the following statements regarding algae 1. There are many types of them in the sea 2. They can detect climate change 3. All have carbon dioxide in their skeletons 4. Different species emit light at different wavelengths when light is shone on them Which of the above statements are incorrect, as per the passage? (a) 3 and 4 (c) Only 2 (b) 2 and 3 (d) Only 3


  9. Q. 1 Consider the following statements regarding algae 1. There are many types of them in the sea 2. They can detect climate change 3. All have carbon dioxide in their skeletons 4. Different species emit light at different wavelengths when light is shone on them Which of the above statements are incorrect, as per the passage? (a) 3 and 4 (c) Only 2 (b) 2 and 3 (d) Only 3


  10. Q. 2 This question consists of an Assertion (A) and a Reason (R). Indicate your answer by selecting the correct alternative. Assertion (A): oceanographers study satellite colour images of the oceans to understand plant life in them. Reason (R): The sea can have different colours depending partly on what plant life it contains. (a) Both A and R are right and R is the correct explanation for A (b) Both A and R are right but R is not the correct explanation for A (c) A is right but R is wrong (d) A is wrong but R is right


  11. Q. 3 Which of the following can be achieved by making colour measurements of the water in the oceans? a) Understanding how much carbon dioxide is in algae skeletons (b) Calculating chlorophyll content in plants in the oceans (c) Finding out the sizes of particles and types of membranes in algae (d) All of the above


  12. Q. 4 Which of the following can be considered to be the central idea of the passage? a) Sensor to detect climate change have een developed (b) Algae influence climate (c) Algae detect climate change by altering their structures (d) The importance of colour measurements of oceans
