Citrus canker is a bacterial disease caused by the bacterium Xanthomonas citri. - It affects the leaves, twigs and fruit of citrus plants, causing the leaves to drop and unripe fruit fall to the ground. - Citrus canker is most severe in hot, wet areas.

When the procedure of bacterial staining is carried out, the Gram negative bacteria stains :
1 red
2 green
3 purple
4 black
Explanation:
When the procedure of bacterial staining is carried out, the Gram negative bacteria stains red. Stains and dyes are used to highlight the microscopic level to study it at higher magnification for histopathological studies and diagnostic purposes. However, staining is not just limited to biological specimens. It can also be used to study the structure of crystalline polymers. - Gram's staining procedure is used to identify becteria based on their cell wall composition.

The cell wall material present only in bacteria and blue-green algae is
1 pectin
2 cellulose
3 chitin
4 muramic acids
Explanation:
Muramic acid is an amino sugar acid. It occurs naturally as $\mathrm{N}$-acetyl muramic acid in peptidoglycan, whose primary function is a structural component of many typical cell walls. - Muramic acid, is a component of the muramyl peptide found only in the cell wall of bacteria and blue green algae.

Which is the hereditary material in bacteria?
1 Nucleic acid
2 Nucleic acid cytoplasm
3 Nucleic acid and histone
4 None of the above
Explanation:
The DNA of most bacteria is contained in a single circular molecule called the bacterial choromosome. The chromosome along with several protiens and RNA molecules, forms an irregularly shaped structure called the nucleiod. This sites in the cytoplasm of the bacterial cell. The genetic material is free irregular, thin fibril double stranded circular DNA.

Mesosomes are found in:
1 Yeast
2 Acetabularia
3 Bacteria
4 Chara
Explanation:
Mesosomes are organelles formed by plasma membrane infoldings and found in the membrane of bacteria. - Mesosome play a role in the formation of cell walls. - They are involved in the replication of DNA in prokaryotic. - Increase plasma membrane surface area and enzymatic content. - Mesosomes are analogous to cristae in the mitochondria in eukaryotic cells.
