The chromosomes become visible under a light microscope during prophase stage of mitosis

Explanation:

Propohase -

The first phase of mitosis , in which the chromosomes becomes visible , as a distinct structure , the nuclear envelope breaks down and the spindle formation takes place .

Hence , this stage is visible under the light microscope.

The next phase is the metaphase , in which the chromosomes line up in middle of cell .

In the third phase , i.e. , the anaphase , the chromosomes moves towards the opposite sides of the vcell .

In the fourth phase , i.e. , the telophase , the two nuclei are formed .

In the last stage , i.e. , cytokinesis , the cell finally divides into two daughter cells .

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
