1. It is a plastid, containing a pigment called chlorophyll. This chlorophyll captures energy from sunlight and helps in the manufacture of food by the process of photosynthesis.   Golgi Apparatus   Mitochondrion   Chloroplast   Cell Membrane   Hint Hint       2. It is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA (Ribonucleic acid).   Lysosome   Chloroplast   Golgi Apparatus   Ribosome   Half-n-half Clue   3. It provides protection, shape and rigidity to the cell. It is freely permeable, allowing substances in the form of solutions to enter and leave the cell without any hindrance.   Chloroplast   Centrosome   Cell Wall   Cell Membrane   Hint       4. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid). After cell division takes place, these chromatin fibres undergo certain structural changes, and are called chromosomes. These chromosomes carry the hereditary information of the genes.   Mitochondrion   Lysosome   Centrosome   Nucleoplasm   Half-n-half Clue   5. It controls and coordinates all the activities and functions of the cell. It plays a vital role in cell division.   Endoplasmic Reticulum   Cell Membrane   Nucleus   Lysosome   Hint       6. It helps in the storage of water and several other substances, namely food, waste products and pigments. It also provides turgidity to the cell.   Vacuole   Nuclear Membrane   Lysosome   Nucleus   Hint       7. It provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and ions.   Mitochondrion   Cell Membrane   Nucleoplasm   Ribosome   Hint
