cell wall
endospore
The immune system helps protect the body by removing bacteria and foreign bodies.
The virus uses a capsid; a protein structure. Bacteria use a peptidoglycan cell wall with one or two cell membranes. Protazoa use different methods. Some have VSP or VSGs; proteins attached to their cell membranes that protect them. Some do not and only have a cell membrane.
US has protected the environment. It has made many protocols.
The skin protects the inner body from not allowing bacteria access in. This is due to the fact that the only entrances through the skin are very small and will only allow molecules in. It isn't quite habitable for the bacteria. The salt, oil, low ph, constant removal of skin, and sweat make it a harsh environment for bacteria to live in.
Bursts in Animal cell But the cell walls and vacuoles protect it in a plant cell
endospore
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.

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,
What can protect bacteria from harsh conditions for even millions of years?
there trying the best they can do to protect their environment.
You protect food to keep germs and bacteria out.
What can protect bacteria from harsh conditions for even millions of years?
Gram positive bacteria protect themselves using antibiotic resistance and their flagella to move. They do not have a membrane like the gram negative bacteria.
