A-3 Cells are the basic units of life. Based on the number of cells, there are unicellular and multicellular organisms. The cells in our body exhibit a variety of shape and size. For example, the shape of a nerve cell (neuron) in animals is very different from the shape of a muscle cell. Some cells of the organisms are spherical or rounded. For example, the shape of the bacteria Cocci is spherical. B-1 The vacuole is membrane-bound space found in the cytoplasm of a cell. It contains excretory product, water, sap and other materials that are not useful for the cell. In the plant cells, vacuoles occupy 90% of the volume of the cell, and they store mineral, salts, sugars, water, etc. They help in maintaining cell fluid balance and shape of the cell by maintaining turgor pressure against the cell wall. C-4 Animal cells are typical eukaryotic cells, enclosed by a plasma membrane and possess a membrane-bound nucleus and other cell organelles, which are well-defined and well-developed. D-2 Prokaryotic cells have a primitive nucleus called a nucleoid, i.e. these cells do not have a well-developed nucleus and cell organelles. All bacterial cells are prokaryotic cells. All these cells have 70S ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. Column I Column II A. Spherical bacteria 3. Cocci B. Membrane-bound 1. Contractile vacuole C.
