What is the benefit form pollen culture :a)Production of hybrid speciesb)Rare plant species can be preservec)Haploid plants can be producedd)None of theseCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Pollen culture ka ye benefit hai ki hame jo plants milte hai wo haploid hote hai...bcz pollen is haploid..bcz tissue culture me jis portion ko use karte hai...hamara plantlets usi ki tarah milta hai...
Means... 2n ----> 2n or n ----> n

So, that's why right answer is 'Haploid plants can be produced'...

$$Hope it's help... $$

Answer

Overcrowding of pollen grains in anther is eliminated and isolated pollen grains are equally exposed to nutrients medium , unwanted growth of the anther wall and other associated tissue are eliminated

Answer

Pollen culture is a technique used in plant tissue culture to produce haploid plants. It involves the in vitro germination of pollen grains and subsequent development of haploid plantlets. The correct answer to the question is option 'C' because the main benefit of pollen culture is the production of haploid plants.

Here is a detailed explanation of the answer:

1. Production of haploid plants:
Pollen culture allows the production of haploid plants, which are plants that have a single set of chromosomes instead of the usual two sets (diploid). Haploid plants are valuable in plant breeding and genetic research because they can be used to produce new varieties through the induction of chromosome doubling. By doubling the chromosome number, a diploid plant is obtained, which can then be used for further breeding or genetic manipulation. Haploid plants are also useful for studying the effects of single gene mutations or for producing homozygous lines in a shorter time frame.

2. Hybrid species production:
Although hybrid species production is mentioned as one of the benefits in option 'A', it is not directly linked to pollen culture. Hybridization is usually achieved through cross-pollination between different plant species or varieties. Pollen culture, on the other hand, focuses on the in vitro development of haploid plants. While haploid plants can be used in hybridization programs, the direct production of hybrid species is not a primary outcome of pollen culture.

3. Preservation of rare plant species:
Option 'B' suggests that pollen culture can be used for the preservation of rare plant species. However, this is not a direct benefit of pollen culture. Rare plant species preservation is typically achieved through conservation strategies such as seed banking, cryopreservation, or ex situ cultivation. Pollen culture primarily aims to produce haploid plants and does not specifically address the preservation of rare plant species.

In conclusion, the correct answer to the question is option 'C' because pollen culture allows the production of haploid plants, which is the main benefit of this technique. Other benefits such as the production of hybrid species or preservation of rare plant species are not directly associated with pollen culture.
