Consider the following statements:
- Moringa (drumstick tree) is a leguminous evergreen tree.
- Tamarind tree is endemic to South Asia.
- In India, most of the tamarind is collected as minor forest produce.
- India exports tamarind and seeds of moringa.
- Seeds of moringa and tamarind can be used in the production of biofuels.
Which of the statements given above are correct?
Detailed Explanation:
Answer: Option 2 — 3, 4 and 5
This question tests knowledge about Moringa (drumstick) and Tamarind trees, their characteristics, economic uses, and potential applications. Out of the five statements, only statements 3, 4, and 5 are correct regarding tamarind collection as minor forest produce, India's exports, and biofuel potential of both plants' seeds.
❌ Statement 1 – Incorrect: Moringa oleifera is a deciduous tree (not evergreen) and belongs to family Moringaceae (not a legume; it lacks nitrogen-fixing root nodules).
❌ Statement 2 – Incorrect: Tamarind (Tamarindus indica) is native to tropical Africa, not endemic to South Asia, though it is widely naturalized in India.
✅ Statement 3 – Correct: Tamarind is collected as Minor Forest Produce (MFP) in India and provides livelihood to tribal and forest-dwelling communities.
✅ Statement 4 – Correct: India is a major exporter of both tamarind and moringa seeds (valued for oil content and medicinal properties).
✅ Statement 5 – Correct: Moringa seeds contain 30-40% oil suitable for biodiesel production, and tamarind seed oil is also being researched for biofuel applications.
