Structures that open and close the stomata

• guard cells

• mesophyll

• cuticle

• epidermis

Why is the leaf lighter green on one side and darker green on the other side

• it is lighter on the side that has the spongy mesophyll

• it is lighter on the side that has the palisade mesophyll

• it is darker on the side that has spongy mesophyll

• it is darker on the side that has a thick cuticle

Why is the leaf a lighter shade of green on the side that has the spongy mesophyll

• there are more chloroplasts in that area

• there are less chloroplasts in that area

• it contains a lot of carotenoids

• it contains a lot of anthocyanins
