1. Chromoplast   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 has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   It is round in shape. It is contained in the nucleus of the cell.   Hint Half-n-half Clue   2. Cytoplasm   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It is a green-colored plastid. It contains a pigment called chlorophyll.   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 has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Half-n-half Clue   3. Cell Wall   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   Hint       4. Leucoplast   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It has a vesicular structure. It is formed when the substances produced in the endoplasmic reticulum are further processed in the golgi apparatus.   It is a colorless plastid. It contains starch.   Half-n-half Clue   5. Smooth Endoplasmic Reticulum   It is a colorless plastid. It contains starch.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   Half-n-half Clue   6. Rough Endoplasmic Reticulum   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 consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Half-n-half Clue   7. Ribosome   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 is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   It is a clear space filled with water or other substances in the form of solutions. It has a covering called tonoplast.   Hint
