Why are microscopes important when studying most cells?
A
Most cells are very large.
B
Most cells are very small.
C
Most cells move very quickly.
D
Most cells are dead.
Explanation: 

Detailed explanation-1: -Because most cells are too small to be seen by the naked eye, the study of cells has depended heavily on the use of microscopes.

Detailed explanation-2: -Microscopes can provide magnifications of 40x to 1000x, which are necessary to see some species since they are so minute. Microscopes allowed scientists to investigate cell structure, observe the tiniest details of plants, animals, and fungi, and learn about the presence of microbes.

Detailed explanation-3: -A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.

Detailed explanation-4: -Microscopes are the backbone of studying biology. The biologists use them to view the details that cannot be seen by the naked eye such as the small parasites and small organisms which is important for the disease control research.

Detailed explanation-5: -Because light needs to pass through the sample, it must be either very small or very thin. Most cells (bacterial or otherwise) are both small and transparent, and so light can easily pass through them.
