1. 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.   It is the largest cell organelle. It has a dense structure. It is spherical in shape.   It is made up of stacks of flattened membranous sacs. It mainly consists of vesicles, vacuoles and tubules.   It is round in shape. It is contained in the nucleus of the cell.   Hint Hint       2. Mitochondrion   It is a green-colored plastid. It contains a pigment called chlorophyll.   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 contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   Half-n-half Clue   3. Nuclear Membrane   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It is a colorless plastid. It contains starch.   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   4. Cell Wall   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 colorless plastid. It contains starch.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   Hint       5. Smooth 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 is a green-colored plastid. It contains a pigment called chlorophyll.   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   Half-n-half Clue   6. Rough Endoplasmic Reticulum   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   It is chiefly composed of a dense fluid. It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid).   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   7.
