Help with plant species?

Question

In science right now we are doing biology. We went to a forest and we had to take pictures of various plants and identify them. Unfortunately, i cant find these species, or, i don't know exactly how to find what they are called.

Does somebody know the names of these plant species?

That last one looks like a species of Equisetum (horsetail), if you mean the blurry one.

You also have 3 photos there of the genus trillium, and at least 2 species. If you find a key to Trillium, you can ID them further.
