Explanation:

The seminal vesicle, bulbourethral glands and prostate gland are three vital accessory glands the seminal fluid for nourishment, motility and protection. Prostrate fluids provide nourishment to sperm cells. The seminal vesicle provides fluid that helps sperm cell to move and source of energy. The seminal fluid is sugar rich in nature mainly fructose.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
