Copper T is placed to prevent pregnancy. It is a intr-uterine device that is placed in the uterus so that there is prevention from joining sperms with egg cell.
Thorns of Bougainvillea and tendrils of Passiflora are homologous structures. These are modified branches and are located at the same position and serve the function of helping in climbing.
