Explanation:
The anther is the male reproductive structure of a flower that contains the pollen grains. The anther consists of several layers of cells, including the cells of the anther wall, the pollen mother cells, and the pollen grains.
Formation of Diploid Plants:
Diploid plants can be obtained through the process of anther culture, which involves culturing the anther in a suitable nutrient medium. During anther culture, both haploid and diploid plants can be obtained.
Origins of Diploid Plants:
The diploid plants obtained in anther culture are derived from the cells of the anther wall. This means that the cells of the anther wall have the potential to give rise to diploid plants.
Reasoning:
- The vegetative cell of the pollen is not capable of giving rise to diploid plants because it is a haploid cell that gives rise to the pollen tube during pollination.
- The exine of the pollen wall is the outermost layer of the pollen grain and does not have the ability to give rise to new plants.
- The generative cell of the pollen is also a haploid cell that gives rise to the sperm cells during pollination. Therefore, it cannot give rise to diploid plants.
Conclusion:
Based on the above reasoning, the cells of the anther wall are the most likely candidates for giving rise to diploid plants in anther culture. These cells have the potential to undergo cell division and give rise to new plants with a diploid chromosome number.

After culturing the anther of a plants few diploid plant were got alon...
Explanation:
The diploid plants obtained after culturing the anther of a plant indicate that there was a process of fertilization and the fusion of male and female gametes.
To determine which part of the anther gave rise to the diploid plant, we need to understand the process of fertilization in plants.
During fertilization in plants, the male gametes are produced within the pollen grain, which is located in the anther. The pollen grain consists of two cells - the generative cell and the vegetative cell.
Here is a breakdown of the options and their role in fertilization:
A: Vegetative cell of pollen
- The vegetative cell of the pollen is responsible for the growth and development of the pollen tube, which helps in the delivery of the male gametes to the ovule.
- The vegetative cell does not contribute to the genetic material of the offspring, so it is unlikely to give rise to a diploid plant.
B: Exine of pollen wall
- The exine is the outer layer of the pollen wall and provides protection to the pollen grain.
- It does not play a direct role in fertilization or contribute to the genetic material of the offspring.
C: Cells of anther wall
- The cells of the anther wall do not directly participate in fertilization but support the development and maturation of the pollen grains.
- However, they are diploid cells and can give rise to diploid plants through a process called somatic embryogenesis or callus induction.
D: Generative cell of pollen
- The generative cell of the pollen is responsible for the production of the male gametes (sperm cells).
- It undergoes mitosis to produce two haploid sperm cells, which participate in fertilization.
- The generative cell does not contribute to the genetic material of the offspring, so it is unlikely to give rise to a diploid plant.
Based on the above analysis, it can be concluded that the cells of the anther wall (option C) are the most likely to have given rise to the diploid plant.
