1. Cell Membrane   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 round in shape. It is contained in the nucleus of the cell.   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 a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   Hint Hint       2. Nuclear Membrane   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   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).   Half-n-half Clue   3. Chromoplast   It is round in shape. It is contained in 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 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.   Half-n-half Clue   4. Vacuole   It has a vesicular structure. It is formed when the substances produced in the endoplasmic reticulum are further processed in the golgi apparatus.   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   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 small, dense and granular structure. It is spherical in shape and is single-walled.   Hint       5. Cell Wall   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 round in shape. It is contained in the nucleus of the cell.   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.   Hint       6. Nucleoplasm   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.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   It is round in shape. It is contained in the nucleus of the cell.   Half-n-half Clue   7. Centrosome   It has a vesicular structure. It is formed when the substances produced in the endoplasmic reticulum are further processed in the golgi apparatus.   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It is a green-colored plastid. It contains a pigment called chlorophyll.   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
