Vedclass · Answer

(A) Statement $A$ is correct: Auxins are known to induce parthenocarpy in many plants.Statement $B$ is correct: Plant growth regulators (PGRs) can act as promoters (e.g.,auxins,gibberellins,cytokinins) or inhibitors (e.g.,abscisic acid) of growth.Statement $C$ is correct: Dedifferentiation (the process where mature cells regain the capacity to divide) is a necessary step before redifferentiation (where cells mature into specific tissues) can occur.Statement $D$ is incorrect: Abscisic acid $(ABA)$ is a plant growth inhibitor,not a promoter.Statement $E$ is incorrect: Apical dominance refers to the phenomenon where the apical bud inhibits the growth of lateral buds,not promotes it.Therefore,statements $A, B,$ and $C$ are correct.
