Step 1: Understanding the Concept:
Botanical classification helps understand the relationships, chemical composition, and physiological requirements of major food crops.
Step 2: Detailed Explanation:
Tapioca (also known as Cassava or Manioc, Manihot esculenta) belongs to the family Euphorbiaceae (the spurge family).
Tapioca is a woody perennial shrub cultivated extensively in tropical and subtropical regions for its highly starch-rich tuberous roots.
It serves as a major dietary carbohydrate source for over 800 million people globally, particularly in Africa and parts of South America and Asia (such as Kerala in India).
As a member of the Euphorbiaceae family, tapioca plants contain specialized cells called laticifers that produce latex, and they synthesize cyanogenic glucosides (linamarin and lotaustralin).
These cyanogenic compounds must be properly processed (through peeling, soaking, and cooking) before consumption to prevent cyanide toxicity.
Other prominent plants in the Euphorbiaceae family include Castor (Ricinus communis), Rubber (Hevea brasiliensis), and Jatropha (Jatropha curcas).
Step 3: Final Answer:
Tapioca belongs to the family Euphorbiaceae.
