Question

Most cells are infinitesimal, and can only be seen under a microscope. In the preceding sentence, what does infinitesimal mean?.

Answer 1

Here, the word infinitesimal means tiny. Most cells can only be visualized under a microscope since they are so tiny.

• In general, all cells must be tiny.
• While not all cells have a sphere-like form, the majority do.
• A cell's surface area grows as the square of its radius as the radius rises, yet its volume grows as the cube of its radius (much more rapidly).
• Thus, a cell's surface area to volume ratio drops as it grows in size. If the cell were in the form of a cube, the same reasoning would hold true (below).
• The plasma membrane won't have enough surface area if the cell enlarges too much to support the rate of diffusion needed to accommodate the larger volume.
• In other words, a cell gets less effective as it develops. One technique to increase efficiency is to divide, while another is to create organelles with specific functions. These modifications result in the emergence of eukaryotic cells, which are more complex cells.

Hence, the correct answer is tiny.
