For my bad plant I choose poison oak. It is in the phylum Anthophyta and its scientific name is Toxicodendron diversilobum. Urushiol oil is what causes the rash produced by poison oak. Only 1 nanogram is needed to cause a rash. Just ¼ of an ounce is needed to give every person on the earth a rash. Urushiol can stay alive for 1-5 years on any surface including a dead plant. It is the most common allergy country and effects half the population. Rubbing the rash won’t spread it if you don’t have the urushiol oil on your hands. Poison oak has three leaves, same as poison ivy.

For my good plant I chose the Northern Red Oak. It can grow from 60 to 90 feet tall and 2 to 3 feet in diameter. It comes from the phylum anthophyta and its scientific name is Quercus rubra. This tree can live up to 500 years old and it reproduces from seeds and root sprouts. This tree can be found worldwide but it is very common in Minnesota and it is the New Jersey state tree. The Northern Red Oak has many uses. It is a good source of lumber and it is harvested and milled in Minnesota because they have an abundant supply of red oaks. It is often used for hardwood flooring, furniture, and for fence posts.
