1. It performs intracellular digestion. It also helps in destroying foreign substances.   Golgi Apparatus   Ribosome   Lysosome   Leucoplast   Hint Half-n-half Clue   2. It provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and ions.   Cell Membrane   Chloroplast   Nucleolus   Lysosome   Hint       3. 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 Wall   Chloroplast   Leucoplast   Golgi Apparatus   Hint       4. It is the site of ATP (Adenosine triphosphate) synthesis. It also synthesizes respiratory enzymes.   Mitochondrion   Nucleoplasm   Cytoplasm   Golgi Apparatus   Half-n-half Clue   5. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid). After cell division takes place, these chromatin fibres undergo certain structural changes, and are called chromosomes. These chromosomes carry the hereditary information of the genes.   Endoplasmic Reticulum   Cytoplasm   Cell Wall   Nucleoplasm   Half-n-half Clue   6. It is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA (Ribonucleic acid).   Nucleus   Ribosome   Mitochondrion   Golgi Apparatus   Half-n-half Clue   7. 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.   Chromoplast   Mitochondrion   Lysosome   Nuclear Membrane   Half-n-half Clue
