From which of the following parts of the plant opium is obtained

  1. New leaves

  2. Roots

  3. Unripe capsule

  4. Seeds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Opium is the dried latex obtained from the opium poppy (Papaver somniferum). Opium latex contains approximately 12% of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade. The latex also contains the closely related opiates 'codeine' and 'thebaine' and non-analgesic alkaloids, such as 'papaverine' and 'noscapine'. The traditional, labour-intensive, method of obtaining the latex is to scratch the immature seed pods (unripe capsule) by hand. The latex leaks out and dries to a sticky yellowish residue that is later scraped off and dehydrated. Thus, option C is correct. 

Opium is not obtained from new leaves, roots and seeds. 
Thus, the correct answer is option C
