Question

Can microorganisms be seen with the naked eyes:
A. Yes
B. No
C. Ambiguous
D. Data insufficient

Answer 1

Hint: The existence of microorganisms was founded during the 1665-1683 and founded by Robert Hooke and Antoni van Leeuwenhoek. Microorganisms or microbes are microscopic organisms which exist in the single celled form or a colony of cells.

Complete Answer:
> Microorganisms generally include the unicellular organism and are extremely diverse. The vast majority of microbes on the earth pose no real threat to humans, plants or animals. They actually work alongside humans which helps with decomposition, decay and even in the digestion of food. There are also some microorganisms which are negatively affecting the human lives, which cause illness, bad odours and damage the product and the surface. Some of the microorganisms include the following bacteria, fungi, algae etc.
> The study of microorganisms is called microbiology. They are also very important in some processes such as climate change, food spoilage, nutrient cycling, biodegradation etc.
> Microorganisms can’t be seen with the naked eyes. So for this reason they are identified in several different ways. Microscopy is a method which is used to identify the cell shape or appearance of the spores. They are often stained to enhance the cellular features and the properties of the cell wall are generally used in the classification of microorganisms.
> Biochemical tests are also used to identify the type of metabolism which is used by a microorganism based on the products it makes from defined substrates.
> So, we can conclude that microorganisms exist as unicellular forms and are widespread in nature and are beneficial to life and also they can cause harmness to the body.

Hence, the correct option is B, “No”.

Note: Microorganisms play a very important role in maintaining the fertility of the soil and they help in many ways serving to ferment foods, and to treat sewage and to produce fuel, enzymes and other bioactive compounds.
