A reproductive cell must differ from other normal body cells. The reproductive cell must because it will soon fuse with another reproductive cell to form a new individual

I'm not 100% sure what the exact answer is to this, because lots of things could be said about what gametes need to do for reproduction.

I suppose since it says that it's combining with another cell, it's hinting at the fact that reproductive cells are haploid.

If this is multiple choice I would choose the choice that has to do with gametes being haploid.

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.
