1. Vacuole   It has a non-living, rigid structure. It is freely permeable and is chiefly composed of cellulose.   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.   It has a double-walled structure. Its inner wall is produced into folds known as cristae. It is generally sausage-shaped.   Hint Hint       2. Secretory Granule   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   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 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   3. Golgi Apparatus   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   It contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It is situated near the nucleus.   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.   Hint       4. Nuclear Membrane   It consists of an irregular network of double-walled tubular membrane. It has ribosomes attached to it.   It consists of an irregular network of double-walled tubular membrane. It does not have ribosomes attached to it.   It is the largest cell organelle. It has a dense structure. It is spherical in shape.   It has numerous pores, making it semi-permeable. It is the covering of the nucleus of the cell.   Half-n-half Clue   5. Cytoplasm   It contains most of the cell organelles.
