For 10 points, name these parts of plant anatomy where gas exchange and photosynthesis take place.
These structures may develop hair-like structures called trichomes in response to damage. These structures are covered in cutin and cutan, which make up the waxy cuticle, while the mesophyll of these structures is divided into pallisade and spongy layers. Oxygen is brought into these structures through openings surrounded by guard cells called stomata, and senescence in these structures is caused by ethylene. Cells in these structures contain chloroplasts and perform the Calvin cycle to fix atmospheric Carbon dioxide.
