The right answer is roots, stems and leaves.
Mitochondria and chloroplasts are not organs but organelles.
Plants, although of very varied morphologies, have in common (with the exception of a few rare groups) of possessing differentiated organs: a stem bearing itself leaves and buds, and for most of them, roots. These organs are themselves made of tissues, organized sets of specialized cells. Among the smaller plants are the mosses, whose leafy stem, a few millimeters to a few centimeters in height, is anchored to the ground by filaments. They have neither roots nor conductive tissues.
