Vedclass · Answer

(B) Monocarpic plants are those that flower and produce seeds only once in their lifetime,after which they die. Cereals like wheat,rice,and maize are annual plants that complete their life cycle in one season,flower once,and then die,making them monocarpic.All sexually reproducing organisms,including monocarpic plants,exhibit distinct phases in their life cycle: the juvenile phase (growth),the reproductive phase (flowering/fruiting),and the senescent phase (aging/death).Therefore,both statements are correct,and the presence of these distinct phases is a general characteristic of all organisms,but the specific reason for being monocarpic is the single flowering event,not just the existence of these phases. Thus,$B$ is the correct choice.
