Question

An important function of botanical Garden is
A. Providing beautiful area for recreation
B. One can observe tropical plants over there
C. They allow ex-situ conservation of germplasm.
D. They provide natural habitat to wildlife

Answer 1

Hint: Botanical gardens are institutions that collect live plants from different plant species: ornamental and cultivated plants, wild, medicinal, economic interests, various geographic areas, special interests. They are valuable not only for botanists, gardeners and loggers, but also for millions of tourists. Ex situ storage is the protection of plants and animals in places outside their natural habitat.

Complete answer:
Botanical gardens are institutions that collect live plants from different plant species:
Role of Botanical Gardens
Taxonomic Research: The Botanical Garden provides valuable information on a variety of plants, native plants, bonsai, rare plants, and more.
Plant Research: The Botanical Garden offers various types of plants, seeds, flowers and fruits for plant research.
Conservation: Botanical gardens preserve and reproduce rare species and genetic diversity.
Education: They provide opportunities for courses on native plants, horticulture, mating, plant breeding, etc. The educational program includes courses for seminars, teachers, students, naturalists.
General service. They help people identify native and exotic plant species. Give instructions for home gardening and plant breeding. Transfer of plant resources; Sale or exchange.
Aesthetics and recreation: attracting people for whom gardening has become a hobby.
Botanic Gardens play a very important role in maintaining a germ-plasm bank of different plant species and act as a depository of ‘endangered’ and ‘extinct’ plant species.. They also play an important role in ex-situ conservation of plant species.
Ex situ storage is the protection of plants and animals in places outside their natural habitat. This includes the collection and conservation of species at specific locations such as botanical gardens, zoos, safari parks, aquariums, and at institutes such as gene banks.
During ex situ conservation, all or part of the plant (i.e. reproductive stock) can be preserved. A long-term alternative to in-situ conservation is ex-situ conservation in botanical gardens, where the whole crop or growing stock is well kept.
Thus, ex-situ conservation in a botanical garden field can be an incentive for researchers and can also help manage crops for future use. At the same time, botanical gardens can raise public awareness of plants and / or plants through advertising.
So it's clear from the above points that options A, B and C all are correct but option D is incorrect. Botanical Gardens do not provide natural habitat to wildlife; it is the function of a zoological garden.
Among correct options the main function of botanical Garden is ex-situ conservation of germplasm.

Hence option (C) is correct.

Note: Plant banking is usually coordinated by the International Bureau of Plant Genetic Resources (IBPGR). IBPGR is also involved in the collection and storage of game species from various genera such as Phaseolus, Glycine, Brassica, Arachis, and others.
Cryopreservation through gene and seed banks, as well as ex situ conservation, are important means of restoring endangered taxa. Botanical gardens in various parts of the world function as medicinal gardens, herb gardens, gardens with economical species, etc. - Preserving various germplasm of the world's flora. Departments from various universities can play a historical role in conservation and exchange programs. In the world.
