Yes. Most bacteria are too small to be seen without a microscope, but in 1999 scientists working off the coast of Namibia discovered a bacterium called Thiomargarita namibiensis (sulfur pearl of Namibia) whose individual cells can grow up to 0.75mm wide..
Subsequently, one may also ask, can be seen without a microscope?
The human eye cannot see most cells without the aid of a microscope. However, some large amoebas and bacteria, and some cells within complex multicellular organisms like humans and squid, can be viewed without aids.
One may also ask, can bacteria be seen with the eye? A Bacterium You Can See With the Naked Eye. It is commonly believed that bacteria are microscopic – stealthy and hidden from the naked eye. But the bacterium, Epulopiscium fishelsoni, is a microbial behemoth you can see with the human eye alone.
In this manner, which bacteria we can see without microscope?
The only visible bacteria without a microscope would be Thiomargarita namibiensis, (i.e the largest bacteria know), with a size of 0.1–0.3 mm, which is still really small and hard to see. The only way you can see bacteria with naked eyes is when they form a colony.
What will happen if there is no bacteria?
Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system. It's likely, the authors write, that most species would experience a massive drop in population, or even go extinct.

Can u see bacteria?
From deep within the soil to inside the digestive tract of humans. In order to see bacteria, you will need to view them under the magnification of a microscopes as bacteria are too small to be observed by the naked eye. Some bacteria are found in bunches and therefore, makes it difficult to see the individual cells.Can people see germs?

How small is a germ?
Bacteria are so small that you cannot see them unless you use a microscope. Just to give you an idea of how small they are, imagine a teaspoon with a BILLION little creatures on it. Those creatures would be bacteria. That means that one bacterium is even smaller than a grain of salt, or the tip of a pin!What is the largest visible cell?
The vast majority of cells are very small. However, the largest single-celled organisms are visible to the naked eye and big enough to hold in your hand. The algae Caulerpa is generally recognized as the largest unicellular organism. However, there are many super-sized one-celled creatures.What are the three basic shapes?

Where do bacteria grow best?
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or low acid. There are exceptions: some bacteria thrive in extreme heat or cold. some can survive under highly acidic or extremely salty conditions.What is the difference between a microbe and a pathogen?
Different diseases are caused by different types of micro-organisms. Microbes that cause disease are called pathogens. A pathogen is a micro-organism that has the potential to cause disease.
