Current Question (ID: 12623)

Question:

Different cells have different sizes. Given are the following cells: I. Mycoplasma II. Ostrich eggs III. Human RBC IV. Bacteria The correct ascending order of their size of the cells given above will be:

Options:

1. I, IV, III, II
2. I, I, III, IV
3. II, I, III, IV
4. III, II, I, IV

Solution:

(a) Represents the correct ascending order of cell's size. Cells in organism vary greatly in their size, shapes and activities. I. Mycoplasmas are the smallest cell with size only 0.3 mm. II. Bacterial cell are of size 30-5um III. In human red blood cells are about 7.0 um in diameter. IV. Ostrich eggs are among the largest cells with size (15x 13)cm. Mycoplasma Like Organisms (MLOs) or mycoplasma are the smallest cell followed by the size of bacterial cell, then RBCs and ostrich egg cell is the largest known cell.
