Tree is to what? Forrest. plant or leaf?

I believe it is a plant. SInce a forest is home to many trees making it not singlar, tress arent necesaily leaves even though they have some. Therefore a plant.

Explanation:

the turtle carries new life, oat seeds, over to the other side of the highway and plants them there.

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
