1. Chloroplast   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   It is a green-colored plastid. It contains a pigment called chlorophyll.   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   It is a colorless plastid. It contains starch.   Hint Hint       2. Cell Wall   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.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   Hint       3. Chromoplast   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   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 living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   Half-n-half Clue   4. Golgi Apparatus   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   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 has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   Hint       5. Leucoplast   It is a colorless plastid. It contains starch.   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   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.   Half-n-half Clue   6. Nucleolus   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It is round in shape. It is contained in 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 green-colored plastid. It contains a pigment called chlorophyll.   Half-n-half Clue   7. Lysosome   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 is the largest cell organelle. It has a dense structure. It is spherical in shape.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   Half-n-half Clue
