Which of the following is the correct order of taxonomic hierarchy? MCQ with Answer and Explanation

Explanation:
Totipotency is the genetic ability of a single plant cell to divide and differentiate into all the cell types of the plant, ultimately generating an entire new plant. This property is the fundamental basis of plant tissue culture. Micropropagation is the technique used to rapidly multiply plants using this totipotency, often through the formation of callus and somatic embryos.

Explanation:
Carolus Linnaeus, a Swedish botanist, is known as the father of Binomial Nomenclature. He introduced this system of naming organisms using two terms: the generic name and the specific epithet. This standardized naming system eliminated the confusion caused by local and common names across different languages and regions.

Explanation:
Xylem is a complex permanent tissue responsible for the unidirectional upward transport of water and dissolved minerals from the roots to the aerial parts of the plant. Phloem is the vascular tissue responsible for the translocation of organic nutrients (primarily sucrose) from sources (leaves) to sinks (roots, fruits), which can be bidirectional. Cambium (vascular and cork) is a lateral meristem responsible for secondary growth (increase in girth); primary growth (increase in length) is driven by apical meristems. Thus, statements 1 and 2 are correct.
