1. It is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA (Ribonucleic acid).   Golgi Apparatus   Cytoplasm   Ribosome   Mitochondrion   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.   Leucoplast   Endoplasmic Reticulum   Nucleolus   Mitochondrion   Half-n-half Clue   3. It initiates and regulates cell division. It also helps in forming spindle fibres, with the help of asters.   Endoplasmic Reticulum   Nucleolus   Cell Wall   Centrosome   Half-n-half Clue   4. It synthesizes and secretes certain substances, namely hormones and enzymes. It also helps in the formation of acrosome of sperm.   Golgi Apparatus   Ribosome   Vacuole   Cell Membrane   Hint       5. It controls and coordinates all the activities and functions of the cell. It plays a vital role in cell division.   Golgi Apparatus   Nucleoplasm   Nucleus   Nuclear Membrane   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.   Golgi Apparatus   Leucoplast   Vacuole   Cytoplasm   Hint       7. 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.   Nucleolus   Leucoplast   Vacuole   Chloroplast   Hint
