Plants, like all living things, need toreproduce. (If a species doesn't reproduce, it will eventually become extinct.) Like animals such as mammals, plants reproduce bycombining special reproductive cellsfrom two parent plants. This creates new plants withcharacteristics of both parents. Unlike mam...
