Question:
Plant organ culture involves the in vitro growth of isolated _______:
Plant organ culture involves the in vitro growth of isolated _______:
Show Hint
Anther and pollen cultures are highly valuable in plant breeding because they yield haploid plants, which can be treated with colchicine to generate completely homozygous double-haploids in a single generation.

- Protoplast
- Plant cell
- Anther
- Callus
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Plant tissue culture can be classified into different types based on the explant used: cell culture, protoplast culture, callus culture, organ culture, and embryo culture.
Step 2: Defining Organ Culture
Organ culture refers specifically to the sterile, in vitro cultivation of structurally intact and organized plant organs (such as roots, shoot tips, leaves, embryos, ovaries, or anthers) where the characteristic architectural structure of the organ is maintained.
Step 3: Comparing Options
- A protoplast is a single cell whose wall has been removed (cellular level).
- A plant cell represents isolated individual cells or single-cell suspensions.
- A callus is an unorganized, amorphous mass of actively dividing parenchymatous cells.
- An anther is a highly organized, multicellular reproductive organ of the plant.
Step 4: Conclusion
Therefore, cultivating an isolated anther is classified as organ culture (specifically anther culture used for haploid production), matching option (C). Final Answer: (C)
