  1. Beautiful area for recreation

  2. Reservoir for tropical plants

  3. Ex situ conservation of germplasm

  4. Natural habitat for wildlife


Correct Option: C
Explanation:

Botanical gardens are sufficiently large sized tracts where plants belonging to different types and localities are grown for scientific and educational purposes. Botanical gardens mainly serve the purpose of providing ex-situ conservation(conservation of selected rare plants/animals in places outside their natural homes) of endangered plant species.

  1. These help in growing important plants of local flora and keeping their record

  2. These help in providing living plant material for research work

  3. These help in growing and maintaining rare and endangered plants

  4. None of these


Correct Option: D
Explanation:

Botanical gardens help in
(i) Providing plant material for comparative taxonomic studies.
(ii) Functioning as acclimatisation centres for exotic plants of economic importance.
(iii) Growing and maintaining records of local flora.
(iv) Providing seeds and living materials for different research work.
(v) Growing and maintaining and endangered plants.

  1. Dried specimens are poisoned by using DDT

  2. The collections are kept inside metallic vasculum

  3. Herbarium sheet is $41\times 29$cm

Correct Option: A

Duplicate of holotype from same collection of same locality, date and same branch of plant is called

  1. Syntype

  2. Paratype

  3. Neotype

  4. Isotype


Correct Option: D
Explanation:
Isotype (in plant taxonomy) A plant specimen that is a duplicate of or very similar to the type specimen and can be used as a reference specimen if the type specimen is lost. In simple language, the isotype is the duplicate of the holotype.
So the correct option is 'Isotype'.
