Question: 96: Which of the following is not a method of ex situ conservation?
(1) Micropropagation
(2) Cryopreservation
(3) In vitro fertilization
(4) National Parks
Answer: Option (4)
Explanation:
Ex situ conservation involves the conservation of biological diversity outside their natural habitats using controlled conditions.
Micropropagation is an ex situ method where plants are multiplied in laboratory conditions using tissue culture techniques.
Cryopreservation is also an ex situ conservation method in which living cells, tissues,
or embryos are stored at very low temperatures to preserve genetic material.
In vitro fertilization is used in ex situ conservation of animals to help in breeding and preservation of endangered species under controlled conditions.
National Parks represent in situ conservation,
where species are protected within their natural habitats.
Therefore, National Parks are not a method of ex situ conservation,
making option (4) the correct answer.
