1. It initiates and regulates cell division. It also helps in forming spindle fibres, with the help of asters.   Centrosome   Chloroplast   Golgi Apparatus   Cytoplasm   Hint Half-n-half Clue   2. It synthesizes proteins by producing and storing RNA (Ribonucleic acid). At the same time, it orders ribosomes to synthesize proteins.   Nucleoplasm   Cytoplasm   Nucleolus   Mitochondrion   Half-n-half Clue   3. It provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and ions.   Mitochondrion   Nucleoplasm   Cell Membrane   Vacuole   Hint       4. 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   Lysosome   Cytoplasm   Chloroplast   Hint       5. It performs intracellular digestion. It also helps in destroying foreign substances.   Endoplasmic Reticulum   Lysosome   Nuclear Membrane   Centrosome   Half-n-half Clue   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   Chloroplast   Golgi Apparatus   Leucoplast   Hint       7. 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.   Chromoplast   Cytoplasm   Cell Wall   Nuclear Membrane   Hint
