Introduction
In plant cells, the apical meristem is a region of actively dividing cells responsible for the growth of the plant. The number of chromosomes in an apical meristem cell is important to determine the number of chromosomes in the telephase of the same cell. In this response, we will discuss the number of chromosomes in the telephase of an apical meristem cell with 2n=28 chromosomes.

Explanation
During the cell cycle, the apical meristem cell goes through different stages, including interphase, prophase, metaphase, anaphase, and telephase. The number of chromosomes in the apical meristem cell during interphase is the same as the number of chromosomes in the telephase.

In the case of an apical meristem cell with 2n=28 chromosomes, the number of chromosomes in the telephase of the same cell would be the same. In other words, the number of chromosomes in the apical meristem cell during interphase, prophase, metaphase, and anaphase would also be 28.

During metaphase, the chromosomes line up at the equator of the cell, and during anaphase, the sister chromatids separate and move towards opposite poles of the cell. In the telephase, the chromosomes reach the opposite poles of the cell and begin to decondense.

The number of chromosomes in the daughter cells formed during cytokinesis is the same as the number of chromosomes in the parent cell. Therefore, the number of chromosomes in the daughter cells formed from the apical meristem cell with 2n=28 chromosomes would also be 28.

Conclusion
In conclusion, the number of chromosomes in the telephase of an apical meristem cell with 2n=28 chromosomes would be 28. This is because the number of chromosomes in the daughter cells formed during cytokinesis is the same as the number of chromosomes in the parent cell.
