1. Cell Membrane   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 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.   Hint Hint       2. Rough Endoplasmic Reticulum   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.   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.   Half-n-half Clue   3. Vacuole   It contains most of the cell organelles. It is composed of a mixture of water and soluble organic & inorganic compounds.   It consists of an irregular network of double-walled tubular membrane. It has 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 is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   Hint       4. Secretory Granule   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 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   5. Cell Wall   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   It has a small, dense and granular structure. It is spherical in shape and is single-walled.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   Hint       6. Mitochondrion   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   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.   It is round in shape. It is contained in the nucleus of the cell.   Half-n-half Clue   7. Nuclear Membrane   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   It has numerous pores, making it semi-permeable. It is the covering of 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.   Half-n-half Clue
