U3 biotest (NOT finished/study cycles on ur own)

Cuticle

-Waxy layer

-waterproof

epidermis (upper & lower)

Protects from predators

Mesophyll

Made up of Palisades & Spongy cell

Guard Cells

-opens & closes stoma

Palisades

-contains chloroplast

-catches sunlight

Spongy cells

-gas exchange

-loosely packed to move gases

Xylem

Moves water

Phloem

Moves food

(Think: “Ph-“ = “F”)

Central vein

Contains both Xylem & Phloem

lumen

Liquid INSIDE a thylakoid

Stroma

Soupy liquid OUTSIDE thylakoid but INSIDE the Chloroplast

Stoma/Stomata

Allows CO2 & O2 in/out of the leaf

Granum

Stack of thylakoids
