Tomatoes are generally referred to as having either Regular Leaf (RL) or Potato Leaf (PL) and as such each will take on a different appearance when growing. Although not grown commercially, potato leaf plants often produce great tasting fruit and home growers will often grow them, because of it.
Here are two photos showing the difference between the two types. Top plant is a Potato Leaf, while the lower is the Regular Leaf.
