Question

Identify the correct statement/s about ex situ conservation. Advanced ex situ conservation includes i. Cryopreservation of gametes. ii. Plant tissue culture method. iii. Seed bank. iv. In vitro fertilisation.

• A. Only ii
• B. i & ii
• C. i,ii,iii,iv
• D. None of the above

Answer 1

The Correct Option is C

Ex situ conservation refers to the conservation of components of biological diversity outside their natural habitats. It involves the preservation of plants, animals, and other organisms outside their natural habitats to save them from extinction.

1. Cryopreservation of Gametes: This is an advanced ex situ conservation technique where gametes (sperm and eggs) are stored at low temperatures to maintain their viability over time.
2. Plant Tissue Culture Method: This is a method of culturing plant cells, tissues, or organs under sterile conditions on a nutrient culture medium. It is used to produce large numbers of plants and preserve genetic material.
3. Seed Bank: Seed banks are collections of seeds stored to preserve genetic diversity. Seeds from these banks can be used to grow plants if their natural populations are threatened or destroyed.
4. In Vitro Fertilization (IVF): This is a technique of fertilizing an egg with sperm in a laboratory setting. It is a part of advanced conservation techniques for endangered species.

The correct option is i,ii,iii,iv as all mentioned techniques are part of advanced ex situ conservation strategies. Each method helps in the conservation of genetic material or species itself, ensuring biodiversity is maintained and species are preserved for future generations.
