Vedclass · Answer

(D) The juvenile phase in plants is the period of growth between germination and the onset of reproductive maturity. This phase is also known as the vegetative phase.When the plant reaches maturity,the juvenile (vegetative) phase ends,and the reproductive phase begins,which is characterized by the formation of flowers.Therefore,statement $A$ is incorrect because it states the end of the juvenile phase marks the beginning of the 'growth phase',whereas it actually marks the beginning of the 'reproductive phase'.Statement $R$ is correct as the juvenile phase is indeed synonymous with the vegetative phase in plants.Thus,$A$ is incorrect and $R$ is correct.
