exists and is an alternate of .

Maybe because bananas are annual kind of plant, which means they can survive in all year round in both rainy season and summer season and it's easy to produce unlike to the other plant to our surroundings. On the other hand, bananas have a juicy stem or body, it has a complete structures of genetic information and besides banana can reproduce itself, without mating from the other plant nor from the other species of banana.(asexual reproduction).
