Thick-walled cells in which bacteria store genetic material are called endospores. Endospores form when bacteria are under stress and help the bacteria survive harsh conditions by protecting the genetic material inside.
Bacteria that produce thick walls around themselves are called Gram-positive bacteria. These bacteria have a thick peptidoglycan layer in their cell wall that retains the purple stain in the Gram staining technique. This thick wall provides structural support and protection to the bacterial cell.
The thick wall formed by bacteria cells that can survive some cooking or freezing temperatures and sanitizing solutions is called a spore. Spores are a dormant form of bacteria that allow them to withstand harsh conditions until they find a more favorable environment to grow and reproduce.
Some bacteria are covered by a thick protective layer called a capsule or slime layer. These structures help the bacteria evade detection by the host immune system and protect them from environmental stressors like desiccation and antibiotics. Capsules can also aid in adherence to surfaces and protect against phagocytosis by immune cells.

No, saprophytes do not have thick walls called endospores. Endospores are a type of resistant structure formed by some bacteria, such as Bacillus and Clostridium, to survive harsh conditions. Saprophytes are organisms that obtain nutrients from decaying organic matter in their environment, such as fungi and some bacteria, but they do not form endospores.
Bacteria cells are prokaryotic, meaning they lack a nucleus and membrane-bound organelles, while mammal cells are eukaryotic with a defined nucleus and complex organelles. Bacteria have a cell wall made of peptidoglycan, whereas mammal cells do not have a cell wall. Additionally, bacteria often have plasmids, small circular DNA molecules, in addition to their chromosomal DNA, which mammal cells lack.
Prokaryotic cells, such as bacteria, do not have a well-defined nucleus, but instead have a nucleoid region where the genetic material is located. They also have a thick cell wall for protection and ribosomes for protein synthesis.
The thick white substance that accumulates at the site of a cut during the healing process is called pus. Pus is a combination of dead white blood cells, bacteria, and tissue debris, and it forms as the body's immune system responds to an infection.
