The smallest free living organism is mycoplasma. It is unicellular smallest prokaryotic organism ranges from $0.1 \mu$ to $00.3 \mu$, which is capable for independent growth reproduction and metabolism also called PPLO (pleura pneumonia like organism). Cell wall absent exhibit polymorphism called "Joker of plant kingdom".

The sexuality in bacteria was established by
1 Lederberg and Tatum
2 H J Muller
3 Hargobind Khorana
4 Ochoa and Kornberg
Explanation:
The sexuality in bacteria was discovered by Lederberg and Tatum (1946). E. coli bacterium in this process gene transfer from one cell to other cell by physical contact called the conjugation.

Cell wall is extremely well preserved in fossil specimen in
1 diatoms
2 dinoflagellates
3 slimemoulds
4 None of these
Explanation:
Diatoms may be either unicellular or colonial the diatoms are important components of marine and fresh water habitats. The cells are normally protected by a wall called a frustules, made up of silica and surrounded by mucilage.

Some bacteria are not easily killed by antibiotics or heat treatment because of their
1 Capsule
2 Chitinous cell wall
3 Mucopeptides in cell wall
4 Mesosomes
Explanation:
Some bacteria are not easily killed by antibiotics and heat treatment because their capsule and mucopeptide cell wall is present. The gram positive bacteria produce endospores during the unfavorable condition. Endospore are tough and resistant structure which remains undamaged during stressful condition.
