1. Vacuole   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 clear space filled with water or other substances in the form of solutions. It has a covering called tonoplast.   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   Hint Hint       2. Mitochondrion   It is round in shape. It is contained in the nucleus of the cell.   It is a membranous sac budded off from the golgi apparatus. It contains several types of enzymes.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   Half-n-half Clue   3. Smooth Endoplasmic Reticulum   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 has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   Half-n-half Clue   4. Ribosome   It is a colorless plastid. It contains starch.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   Hint       5. Rough Endoplasmic Reticulum   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 double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   Half-n-half Clue   6. Cytoplasm   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   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. Cell Membrane   It is the largest cell organelle. It has a dense structure. It is spherical in shape.   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 has a living, flexible and thin structure. It possesses fine pores, making it semi-permeable. It is chiefly composed of lipo-proteins.   Hint
