1. Chromoplast   It is round in shape. It is contained in the nucleus of the cell.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   It is a clear space filled with water or other substances in the form of solutions. It has a covering called tonoplast.   It is a plastid that is colored differently in different cells. It contains pigments such as xanthophyll (yellow in color) and carotene (orangish-red in color).   Hint Half-n-half Clue   2. Golgi Apparatus   It has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   Hint       3. Nucleoplasm   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   It is round in shape. It is contained in the nucleus of the cell.   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   Half-n-half Clue   4. Leucoplast   It is a colorless plastid. It contains starch.   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It is round in shape. It is contained in the nucleus of the cell.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   Half-n-half Clue   5. Rough Endoplasmic Reticulum   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   Half-n-half Clue   6. Centrosome   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Half-n-half Clue   7. Smooth Endoplasmic Reticulum   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   It is a colorless plastid. It contains starch.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   It has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   Half-n-half Clue
