Bacteria can act as decomposers, breaking down organic matter and recycling nutrients in the environment. They can also be beneficial by aiding in digestion, producing vitamins, and helping protect against harmful pathogens. However, some bacteria can also be harmful, causing infections and diseases in humans and other organisms.
Bacteria from the environment can be present in the air we breathe, but our respiratory system has natural defenses that can help protect against harmful bacteria. Inhaling large amounts of bacteria can potentially lead to respiratory infections. It is important to maintain good hygiene and avoid situations where there is a high risk of inhaling harmful bacteria.
The thick-walled structure in bacteria that contains the chromosome and a small amount of cytoplasm is called an endospore. Endospores are formed under stressful conditions such as nutrient deprivation to protect the bacterial DNA and ensure survival.
The amniotic fluid provides a cushioning effect to protect the fetus from physical trauma, serves as a barrier against infection by preventing the entry of bacteria or viruses, and helps maintain a stable temperature environment for the fetus to develop properly.
endospore
In a hypotonic environment, a plant cell will swell due to water flowing into the cell by osmosis. This can cause the cell to become turgid, which is important for maintaining turgor pressure and structural support in plant cells. If the cell takes in too much water, it may burst, a process known as lysis.
the cell is covered in membrane and it surrounds the cell to protect anything like bacteria from getting in and out of the cell.
On our skin and even inside our own bodies, like the digestive tract, we have bacteria, considered to be our own micro flora, these are bacteria picked up in our environment that protect us. If you are away from home sometimes, because we are not normally exposed to some types of bacteria our micro flora may not be effective. But it is possible to get immunizations, that will help our bodies build up antigens to protect us.

What can protect bacteria from harsh conditions for even millions of years?
Bacteria usually lack capsid. However, certain bacteria have capsid-like proteins which can be the cause of certain infections. Almost all viruses contain this protein and can cause diseases as it protect the virus inner DNA/RNA structure,

Gram positive bacteria protect themselves using antibiotic resistance and their flagella to move. They do not have a membrane like the gram negative bacteria.
