Modified Leaf of a Plant
These are two leaves from a forest that was harvested and is now thick with new growth. The leaves are so large because they are fighting for sunlight among the rest of the growth which is why they are considered modified plant leaves.
Spore
This is a puffball fungi that when stepped on or touched releases a smoke-like puff of spore out its top.
Introduced Species
In my father's hand is a branch of an autumn olive plant. The plant is not originally from the United States and is considered an invasive introduced species.
