Which part of the leaf has air spaces to allow carbon dioxide to flow through the leaf and diffuse into cells.

• epidermis tissue

• palisade mesophyll

• spongy mesophyll

• xylem

What is transported in the xylem

• water and mineral

• sugar

what is transported in the phloem

• water

• sugars made by photosynthesis

what are the name of the pores that allow carbon dioxide to enter the leaf

• tomato

• stomata

• so matter

There are more stomata on the lower side of the leaf, because

• rain does not run into the pore

• it is cooler on the lower side so there is less evaporation of water

• There is a higher contraction of carbon dioxide on the lower surface.

The outside layer of cells in the leaf are called the

• epidermis

• epithelial

• plant skin
