The bunchy top of the papaya is caused by Phytoplasma. They are the bacterial parasites that are similar to mycoplasma. - The little leaf disease is caused by the Phytoplasma in the brinjal plant. - Witches broom disease is a type of disease caused by stress or mycoplasma.

The inner most membrane of gram (-) negative bacteria is consist of :
1 mucopeptide
2 lipoprotein
3 phospholipid
4 lipopolysaccharides
Explanation:
The inner most membrane of gram negative bacteria is plasma membrane which consist of lipoprotein while outer cell wall which consist of mucopeptide. Cytoplasm of all bacteria cells are surrounded by an inner membrane composed of phospholipids which is enclosed by the cell wall a macromolecular network of peptidoglycan that is single layered. - The outer membrane of Gram-negative bacteria contains lipo-polysaccharides, proteins and phospholipids.

Product of photosynthesis in blue-green algae is
1 glycogen like
2 glucoside
3 globulin
4 glycerol phosphate
Explanation:
Cyanobacteria is autotrophic eubacteria and make their food with the help of oxygen present in water. - The cell structure in cyanobacteria is typically prokaryotic. - Photosynthetic pigment of cyanobacteria is chlorophyll A and $\beta$-carotene and reserve food material is cyanophycean starch like glycogen.

Aerobic bacteria found in hot sulphur springs are termed as
1 halophiles
2 thermoacidophiles
3 chemolithotrophic
4 None of the above
Explanation:
The microorganisms that have developed mechanism to successfully persist in hot, acidic environments are known as thermoacidophiles. - Thermoacidophiles like Thermoplasma and Thermoproteus are the archaebacteria which have the two fold ability to tolerate a high temperature as well and acidic environment. - They are habitually found in acidic sulphur springs where the temperature may exceed $80^{\circ} \mathrm{C}$ and $\mathrm{pH}$ be as low as 2 . - They are chemosynthetic as they obtain energy by synthesizing food from oxidizing sulphur to sulphuric acid.
