Description
Ten (10) students say the top of the leaf takes in gases because when rain and watering cans water plants it comes from above and hits the top of the plant leaves first. Ten (10) say the bottom of the leaf takes in gases because after observing the leaves from each plant the bottom of the leaves were more veiny and the skin of the bottom leaves seemed thinner. The top of the plant leaf had a thicker, waxy covering and it looked like water would be hard to get through it.
