Hint: Cells are microscopic and the unit of measurement has the word in the instrument used for visualizing cells.
Complete answer: Cells are microscopic and they cannot be seen by the naked eye. It is visualized with the help of a microscope. There are many types of the microscope; the compound microscope, fluorescent microscope, contrast microscopes, electron microscope, etc. They are measured by unit micrometers (μm). One micrometer is 10-6 of a meter.
The sizes of different cells are given as follows:
1. Eukaryotic cells range between 1– 100µm in diameter.
2. Normal RBCs have a diameter of 6 - 8 μm.
3. Neurons are several micrometers long, they can sometimes be meters long.
4. A sperm cell can range in length between 40.45–54.04 μm.
5. An ovum can be as large as 100 microns in diameter.
6. Micrometers are used by pathologists, nanotechnologists, etc.
Additional information: $Å$ is known as angstroms.
1. One angstrom is equal to 10 –10 meters.
2. It is also frequently used in several fields of science
3. nm Is known as nanometer; it is equal to 10–9-meter
4. mm is known as millimeter; it is one-thousandth of a meter
So the correct answer is Option 4: μm
Note: Other units of measurement are decimeter (dm), decameter, picometer (pm). Femtometer (fm), centimeter (cm), kilometer (km), zeptometer (zm), yoctometer (ym), etc.
2. Smaller lengths like nanometer, angstroms are used in chemistry and atomics to measure the interatomic distance and diameters of several molecules.
3. Zacharias Janssen is known for his pioneering work in the invention of the microscope.
4. Anton Von Leuwenhoek developed his crude microscope and he observed the cork cells of the bark of a tree.
5. Ostrich cell is the largest single cell in the world.
