A seedless orange is typically grown from a rootstock that has been specifically bred to be seedless. While the fruit itself might not produce seeds, the rootstock used to grow the tree will have the genetic makeup necessary for producing and sustaining the tree. This process allows seedless fruit trees to be grown and propagated despite the absence of seeds in the fruit.

Mushrooms typically grow within a few feet of their host tree, as their root-like structure extends into the soil around the tree to gather nutrients. However, there are some mushrooms that can grow further away from their host tree depending on the species and environmental conditions.
