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.   Golgi Apparatus   Nuclear Membrane   Chromoplast   Centrosome   Hint Half-n-half Clue   2. It controls and coordinates all the activities and functions of the cell. It plays a vital role in cell division.   Chloroplast   Nucleus   Chromoplast   Cell Wall   Hint       3. It provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and ions.   Cell Membrane   Chromoplast   Cytoplasm   Cell Wall   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.   Chloroplast   Nuclear Membrane   Nucleoplasm   Mitochondrion   Hint       5. It is semi-permeable, allowing substances to enter and leave the nucleus of the cell. It also provides protection to the nucleus of the cell.   Lysosome   Ribosome   Cell Wall   Nuclear Membrane   Half-n-half Clue   6. It synthesizes proteins by producing and storing RNA (Ribonucleic acid). At the same time, it orders ribosomes to synthesize proteins.   Ribosome   Nucleolus   Chloroplast   Nucleoplasm   Half-n-half Clue   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   Cell Wall   Lysosome   Nuclear Membrane   Hint
