Something that potatoes and bacteria could have in common would be that they both reproduce asexually.
Potato is a plant with crawling attributes and has the capacity to be propagated by cutting parts of the crawling stem. In addition, potato tubers have nodes from which new plants can arise. In other words, potato is mainly propagated vegetatively either from stems or from tubers. Vegetative propagation is a form of asexual reproduction.
Bacteria, on the other hand, have the capacity to reproduce by an asexual method known as binary fission. A bacterial cell divides to form two new cells that are genetically and morphologically similar to the parent cell.
Hence, both potatoes and bacteria have the capacity to reproduce in asexual ways. Although bacteria sometimes reproduce sexually in addition to asexual reproduction.
