During plant tissue culture technique student wants to obtain triploid plant. Which part he should select foot culturing *
1.Stigma
2.Anther
3.Endosperm
4.zygote
Answers
Answer: The correct answer is Endosperm.
Explanation:
The stigma is a specially adapted portion of the pistil modified for the reception of pollen. It’s diploid(2n) structure.
Anther- It is the part of the stamen where pollens are produced. It is the male part of the flower and it contains pollen grains. It is diploid structure (2n).
The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes).
The endosperm is a tissue produced inside the seeds of most of the flowering plants following double fertilization.
It is triploid 3n (meaning three chromosome sets per nucleus)
Angiospermic endosperms are triploid(3n) in nature. Thus, by culturing endosperm, we can obtain triploid plants.
During the plant tissue culture technique, the student wants to obtain a triploid plant. The part that he should select for culturing is Endosperm.
We know that stigma, anther, and zygote have a diploid structure whereas endosperm is triploid. It is produced following double fertilization and has three chromosome sets per nucleus.
Therefore, by culturing endosperm, triploid plants can be obained.
