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 species outside their natural habitats. Advanced ex situ conservation techniques include:

• Cryopreservation of gametes: This involves the freezing of gametes (sperm, eggs, or seeds) for long-term storage. It is a crucial method for preserving the genetic material of endangered species.
• Plant tissue culture method: This technique allows for the growth of plant cells or tissues under controlled conditions, enabling the conservation and regeneration of endangered plant species.
• Seed bank: Seed banks store seeds from a wide variety of plants, preserving genetic diversity for future restoration or research.
• In vitro fertilization: This technique involves fertilizing eggs outside the organism, which can be used for breeding endangered species or plants.

Since all these methods are part of advanced ex situ conservation techniques, the correct answer is:

The correct answer is (C) : i, ii, iii, iv.
