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.   Cell Membrane   Lysosome   Chloroplast   Ribosome   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).   Nuclear Membrane   Chloroplast   Vacuole   Ribosome   Half-n-half Clue   3. It synthesizes proteins by producing and storing RNA (Ribonucleic acid). At the same time, it orders ribosomes to synthesize proteins.   Leucoplast   Nucleolus   Cytoplasm   Golgi Apparatus   Half-n-half Clue   4. It is the house of all metabolic activities and functions in the cell. In other words, it contains most of the cell organelles, each of which perform a specific function.   Cytoplasm   Nucleus   Nuclear Membrane   Endoplasmic Reticulum   Half-n-half Clue   5. 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.   Leucoplast   Chloroplast   Chromoplast   Cell Wall   Half-n-half Clue   6. It is the site of ATP (Adenosine triphosphate) synthesis. It also synthesizes respiratory enzymes.   Nuclear Membrane   Ribosome   Mitochondrion   Chloroplast   Half-n-half Clue   7. It helps in the storage of water and several other substances, namely food, waste products and pigments. It also provides turgidity to the cell.   Lysosome   Vacuole   Mitochondrion   Ribosome   Hint
