cell wall
Most bacteria are surrounded by an endospore. They form these when exposed to extreme temperatures or harsh conditions.
amniotic sac :)
Angiosperms produce seeds. In an angiosperm eggs develop in a protective structure called the ovary. As seeds of an angiosperm develop, the ovary changes into a fruit.
It the usefulness of enzyme for which it is named after. As the enzyme restriction endonuclease restrict the entry of foreign DNA in the bacteria. So it can be called a protective mechanism of bacteria and it is believed to be evolved by bacteria to resist viral attack.
flagellum
Capsules. Encapsulated organisms are very tough for the body to resist because they are hiding inside a polysacharide or polypeptide shell that phagocytes do not recognize as foreign pathogens. This also means that most encapsulated bacteria are among the most pathogenic of all. Most capsule formers are responsible for horrific diseases because the body has little resistance against them.
amniotic sac :)
a barrier
No - They are surrounded by a protein coat called the capsid
The resting period of bacteria is called the dormant period
Lysosomes
its change its color according to its environment that animals called CAMOUFLAGE
This structure is called as Cell Wall that gives shape to the bacteria. This wall gives protection to the bacteria and prevents it from exploding because of osmotic lysis.
Angiosperms produce seeds. In an angiosperm eggs develop in a protective structure called the ovary. As seeds of an angiosperm develop, the ovary changes into a fruit.
Bacteria are surrounded by endospheres which contain genetic material and keeps the bacteria safe until conditions are right for it to live again.
It the usefulness of enzyme for which it is named after. As the enzyme restriction endonuclease restrict the entry of foreign DNA in the bacteria. So it can be called a protective mechanism of bacteria and it is believed to be evolved by bacteria to resist viral attack.
A bacteria moves using a structure called the flagellum, which resembles a tail.
I believe you are looking for the organelle called a Ribosome(s)
