1. Cell Wall   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   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.   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   Hint Hint       2. Secretory Granule   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 contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   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   3. Chromoplast   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   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 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.   Half-n-half Clue   4. Cytoplasm   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 has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   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   5. Smooth Endoplasmic Reticulum   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   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 does not have ribosomes attached to it.   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   6. Nucleoplasm   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 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 numerous pores, making it semi-permeable. It is the covering of 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).   Half-n-half Clue   7.
