Question

Preservation of genetic materials of threatened trees in cryopreservation is covered under __________.

• A. In-situ conservation
• B. Ex-situ conservation
• C. Circa situm conservation
• D. In-ex-situ conservation

Hint:

Any conservation method that relies on human-controlled facilities (like botanical gardens, zoos, seed banks, or cryopreservation units) falls under ex-situ conservation.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Biodiversity conservation strategies are broadly categorized based on whether the genetic resources are maintained inside or outside their tural habitats.

Step 2: Detailed Explation:
Let us distinguish the conservation strategies:
• In-situ conservation: Protecting plants and animals within their tural habitats, such as tiol parks, biosphere reserves, and sacred groves.

• Ex-situ conservation: Protecting species outside their tural habitats in controlled environments. This includes botanical gardens, seed banks, gene banks, pollen banks, tissue culture, and cryopreservation.

• Circa situm conservation: Preserving wild species within agricultural landscapes close to their tural habitats.
Cryopreservation involves storing biological materials (such as seeds, embryos, or shoot tips) at ultra-low temperatures, usually in liquid nitrogen at \(-196^\circ\text{C}\).
Because this process occurs entirely in a laboratory or gene bank outside the tural forest habitat, it is classified as ex-situ conservation.

Step 3: Fil Answer:
The correct option is (B).
