Which of the following options show the characters of mycoplasma?
1 Smallest living cell without cell wall survive with oxygen.
2 Smallest living cell with cell wall survive with oxygen
3 Smallest living cell without cell wall survive without oxygen.
4 Smallest living cell with cell wall survive without oxygen.
Explanation:
Dienes and Edsall(1937) detected first Mycoplasma isolated from humans in a Bartholin's gland abscess. It is unicellular smallest prokaryotic organism, which is capable for independent growth, reproduction and metabolism, also called PPLO (pleuropneumonia like-organism) cell wall absent exhibit polymorphism called "Joker of the plant kingdom" cell membrane made up of lipoproteins, mesosomes are absent.

Bacterial toxins when excreted into the surrounding medium are known as :
1 toxins
2 endotoxins
3 exotoxins
4 both $[\mathrm{b}]$ and $[\mathrm{c}]$
Explanation:
Exotoxins:- Exotoxins are usually heat labile proteins secreted by certain species of bacteria which diffuse into the surrounding medium. An exotoxin can cause to damage to the host by destroying cells or by disrupting normal cellular metabolism. Pathogenic bacteria that produce exotoxin mainly include Clostiridium tetani, Clostridium botulinum, Vibrio cholera.
