1. Golgi Apparatus   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 small, dense and granular structure. It is spherical in shape and is single-walled.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   Hint Hint       2. Cell Wall   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 has ribosomes attached to it.   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       3. Chromoplast   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   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 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   4. Vacuole   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It is a clear space filled with water or other substances in the form of solutions. It has a covering called tonoplast.   Hint       5. Lysosome   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 is the largest cell organelle. It has a dense structure. It is spherical in shape.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   Half-n-half Clue   6. Centrosome   It has numerous pores, making it semi-permeable. It is the covering of 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 double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   Half-n-half Clue   7. Nuclear Membrane   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It is the largest cell organelle. It has a dense structure. It is spherical in shape.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   Half-n-half Clue
