1. Chloroplast   It is a green-colored plastid. It contains a pigment called chlorophyll.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   It has a vesicular structure. It is formed when the substances produced in the endoplasmic reticulum are further processed in the golgi apparatus.   Hint Hint       2. Nucleoplasm   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Half-n-half Clue   3. Smooth Endoplasmic Reticulum   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   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).   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   Half-n-half Clue   4. Cell Wall   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   It is a clear space filled with water or other substances in the form of solutions. It has a covering called tonoplast.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Hint       5. Centrosome   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   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 vesicular structure. It is formed when the substances produced in the endoplasmic reticulum are further processed in the golgi apparatus.   Half-n-half Clue   6. Chromoplast   It is a colorless plastid. It contains starch.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   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).   Half-n-half Clue   7. Leucoplast   It is a colorless plastid. It contains starch.   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   It is round in shape. It is contained in the nucleus of the cell.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Half-n-half Clue
