Correct Answer - Option 3 : infected agar-wood
EXPLANATION:
- The agar oil is obtained from the INFECTED AGARWOOD.
- Agarwood is dark resinous wood.
- It is found in the trees of genus Aqualaria, which are primarily found in south and southeast Asia, only when the heartwood is infected with a fungus from the genus Phialophora.
- The heartwood of the uninfected Aquilaria tree can not be used for the extraction and production of Agaroil because it is light in color and odorless.
- Only after the infection, from the respective fungus, the fungus makes the heartwood dark and aromatic, thus being called AGARWOOD and becoming perfect for the process of agar oil extraction.
- The agar oil is extracted through the process of distillation by collected the infected agarwood.
The correct answer is - infected agarwood
USES OF AGAROIL -
-
In making medicines, perfumes, and incense
- It has sedative, carminative, and anti-emetic effects (effective against vomiting and nausea), which is why it is used in making medicines.
PARASITES -
- The species Phialophora parasitica, from the genus Phialophora, is a fungus that acts as a parasite on its host.
- A parasite is defined as - "an organism that lives on or in another organism's body to obtain its food directly from that organism in which it is living."
- The organism on which or within it is living is called the host. in this case, Phialophora parasitica is thus a parasite that infects the tree and extracts its food from the heartwood.
- Found at the center of the tree trunk and is the region to find the hardest and the toughest timbre.
- The central core of the trunk
- The cells of the heartwood are comparatively older and are full of raisin and tannins
ENDANGERED - (an animal or plant species that is on the verge of extinction)
- The loss of the wild habitat and the changing climatic conditions is one of the key explanations for agarwood's relative scarcity and high price.
- The primary source, Aquilaria Malaccensis, has been on the Convention on International Trade in Endangered Species of Wild Fauna and Flora's Appendix II (potentially threatened species) list since 1995.
- All Aquilaria species were described in Appendix II in 2004, although there were a few exceptions.
AGARWOOD |
AGAR-AGAR |
The dark-colored, filled with fragrance heartwood due to fungal infection is called agarwood which has other names like aloes or agar. |
AGAR- AGAR is taken or extracted from red algae found in oceans. |
Agarwood is found on land, in the heartwood of infected trees of Aqualaria. |
The agar, used as a culture medium or gelling substances in food is obtained through the red algae found in the oceans. |
- Both these terms are different and not be mixed and matched with one another.
- One is taken out from the ocean's red algae and one from the trees of south and southeast Asia.
