The figure given represents the life cycle of a plasmodial slime mould. In the life cycle figure, label F represents feeding plasmodium stage. The plasmodium is made up of millions of nuclei which share a single, large cell without any membranes to separate them. Therefore, label F in the figure is more like many workers in large meeting room.
Many workers in a large meeting room well to me you see most of them have little holes in them so I think of it as rooms and the label f has fewer holes than the other so I think of it as a lot of workers in one area. so I think that is your answer but I'm not really sure.
