KENDRIYA VIDYALAYA, BADMAL: SUMMER BREAK TASK: Subject: Biology (Science) SECTION A (HOTS) & PREVIOUS YEARS QUESTION ANSWERS 1) Which structure do the cork cells resemble as observed by Robert Hooke? 1 Honey comb structure. 1 2) State the function of chromosome in a cell. 1 Chromosome is the carrier of genetic information. 1 3) What is the importance of osmosis in

4 (a) Unicellular organisms 2 Unicelluar gain water by osmosis (b) plants? Plants roots absorb water by osmosis 1+1 4) (a) Why is plasma membrane called selectively permeable membrane? (b) How is flexible nature of plasma membrane useful for Amoeba? Name this process. 3 (a) It allows the entry and exit of some materials in and out of the cell, and prevents movement of some other materials. (½+½) (b) It enables cells to engulf food and other materials from its external environment. Amoeba acquires food through this process. (½+½) The process is called endocytosis 1 5) Name the processes by which CO 2 and H 2 O move into and out of the cell? 1 By diffusion and osmosis. ½, ½ 6) What will happen if: (a) ribosomes are removed from the cell, (b) golgi apparatus is removed from the cell, (c) plasma membrane ruptures? 3 (a) Protein will not be synthesized (b) Packaging of materials, synthesis of complex sugar and formation of lysosome will be adversely affected (any one of these) (c) The inside materials will come out ) Describe the role played by the Lysosomes. Why these are termed as suicidal bags? How do they perform their function? 3 Role-digestion of foreign material, digestion of worn out organelles; because these burst themselves and digest the own cell; lysosomes are filled with digestive enzymes. Capable of breaking down all organic material ) Explain your observation in the following with reason involved in the process. 3 (a) Salt is applied to raw mango pieces (b) Dried raisins are kept in water for a few hours. (a) Mango pieces will shrink due to exosmosis in which more water molecules will go out (b) Raisin will swell up because medium surrounding it has higher concentration of water than the cell. Raisin gains water due to osmosis. 1½+1½ 9) (a) What is DNA? Mention its function? Where is it found? (b) Name the functional segment of DNA. 2

5 12) (a) DNA or Deoxyribo Nucleic Acid molecule. ½ Contains information necessary for constructing and organising cells and inheritance of features from parents to next generation. ½ They are found in chromosomes. ½ (b) Genes. ½ 10) (a) Name the two types of endoplasmic reticulum (b) What crucial role does it play in the liver cells of vertebrates? (c) Mention it s any other function. 2 (a) Rough endoplasmic reticulum and smooth endoplasmic reticulum.1 (b) Detoxifying many poisons and drugs. ½ (c) Functions of ER: ½ ER forms a network in cytoplasm, giving mechanical support to the cell. It functions as an intracellular transport system for substances like nucleoproteins. Protein Synthesis occurs on the surface of rough ER by ribosomes. Synthesis of lipids occurs on the surface of smooth ER. (Any one) 11) State if the following situations are possible 3 (i) An object has travelled a certain distance but still its displacement is zero. (ii) An object has travelling with a constant speed has acceleration. Justify your answers with suitable examples. 12) How would (i) a plant cell (ii) an animal cell behave when placed in a hypotonic solution of sodium chloride? Explain giving reasons. (Present your answer in a tabular form) 3 Plant cell swells, does not burst, because of the cell wall. Animal cell swells, bursts because of the absence of a cell wall. 1½+1½ 13) (a) What would happen to the life of a cell if there was no Golgi apparatus? (Any two) (b) Which two cell organelles of a cell contain their own genetic material? (c) What happen if the organisation of a cell is destroyed due to some physical or chemical influence? (1+1+1)=3 (a) There will be effect on the packaging and dispatching of different types of Proteins. The products of the cell cannot be stored. The products of the cell cannot be modified further.(any two)(½+½) (b) Mitochondria and Plastids. (½+½) (c) Each living cell has the capacity to perform certain basic functions due to its cell organelles which are responsible for its organisation.

6 If this organisation of a cell is destroyed, the cell will not be able to perform certain basic functions and ultimately it will die soon.
