Need help on three more.

The pictures below are of plants again on my property......
I did some research and decided that #1 could be a red mulberry.... are these fruits or am I wrong?
#2 I believe to be sassafras but there is no smell to the flowers or leaves.....
There are vines crawling all over this tree.... could that cause a lack of smell or is this not what I thought.

#3 is a vine that is not yet in bloom but should be soon.
Thank you so very much.

I am very sorry about the quality of the pics...... I can try for better if needed

 

#2 Sassafras albidum

 

#1 yes, mulberry flowers which are developing into fruits

 

In order for it to have done this don't I also need a male plant? If so how would I identify it?

 

The male and female flowers are usually on different trees in M. rubra. Pollen can travel a long ways. http://www.duke.edu/~cwcook/trees/moru.html

 

Might need to post a photograph of that vine when it's in flower.
