leaf anatomy

#1 - outermost layer and not made of cells; helps regulate water loss.

• Epidermal cells

• Palisade cells

• Xylem cells

• Waxy cuticle

#2 & #5 - outermost layer of cells; provides protection from outside elements.

• Epidermal cells

• Palisade cells

• Phloem cells

• Waxy cuticle

#3 - layer of tall, columnar cells that contain many chloroplast for photosynthesis

• Epidermal cells

• Guard cells

• Pallisade mesophyll

• Spongy mesophyll

#4 - layer of irregular cells with space in between the cells

• Pallisade mesophyll

• Phloem

• Spongy mesophyll

• Xylem

#6 - porous opening in the bottom of the leaf that allows for gaseous exchange

• Pallisade mesophyll

• Spongy mesophyll

• Stomata

• Vein

#7 - two cells that surround each porous opening; regulates gaseous exchange by opening and closing the pore.

• Epidermal cells

• Guard cells

• Stomata cells

• Xylem cells

#8 - Cell tissue that makes up part of each vein that transports glucose and nutrients throughout the plant

• Epidermal cells

• Guard cells

• Phloem cells

• Xylem cells

#9 - Cell tissue that makes up part of each vein that transports water throughout the plant

• Epidermal cells

• Guard cells

• Phloem cells

• Xylem cells
