Exercise 3: Cell Structure of Exercise 3: Cell Structure of Primary Tissues…Lab Study C: Primary Tissues…Lab Study C: LeavesLeaves

Observe prepared slide of Leaf cross section (lilac leaf)

View Leaf model as reference on leaf cells

Observe prepared slide of Stinging nettle trichomes. Trichomes (modified epidermal cells) that

function in defense. Each trichome consists of a bulb filled with formic acid. The trichome injects the chemical irritant into the skin of an animal that touches the plant.
