1. It is a plastid, containing pigments such as xanthophyll (yellow in color) and carotene (orangish-red in color). These pigments impart color to flowers and fruits of plants.   Cytoplasm   Ribosome   Nucleoplasm   Chromoplast   Hint Half-n-half Clue   2. It initiates and regulates cell division. It also helps in forming spindle fibres, with the help of asters.   Nucleus   Nucleolus   Centrosome   Vacuole   Half-n-half Clue   3. It helps in the storage of water and several other substances, namely food, waste products and pigments. It also provides turgidity to the cell.   Nucleolus   Vacuole   Lysosome   Chloroplast   Hint       4. It is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA (Ribonucleic acid).   Ribosome   Golgi Apparatus   Mitochondrion   Chromoplast   Half-n-half Clue   5. 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.   Vacuole   Nucleolus   Nucleoplasm   Chloroplast   Hint       6. It is a plastid. It helps in the storage of starch.   Vacuole   Nucleolus   Leucoplast   Ribosome   Half-n-half Clue   7. It provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and ions.   Nuclear Membrane   Cell Membrane   Endoplasmic Reticulum   Nucleoplasm   Hint
