Q.1
Given below are two statements
Statement |: Candidatus phytoplasma is a wall-less prokaryoteStatement I : l: Candidatus phytoplasma colonize in plant phloem
In light of the above statements, choose the most appropriate answer from the options given below.
- Biology of Phytoplasmas: Statement (I) is correct because Candidatus Phytoplasma represents a genus of specialized, wall-less obligate prokaryotes belonging to the class Mollicutes. They lack a peptidoglycan cell wall and are bounded solely by a triple-layered unit membrane.
- Tissue Tropism: Statement (II) is correct because phytoplasmas are strictly confined to the phloem sieve tubes of infected host plants, where they feed on rich sugars and amino acids, and are vector-transmitted between plants by phloem-feeding sap-sucking insects (leafhoppers, planthoppers, and psyllids).
- Conclusion: Both Statement (I) and Statement (II) are correct (Option 1).
