phloem
sugar conducting
sieve element
paired with companion cells to transport carbohydratest
companion cell
found with sieve elements and help transport carbohydrates/sugars
cambium
layer of cells around the stem (secondary growth)
xylem
water-conducting
tracheid
water conducting cell in the xylem
vessel element
tracheids that have perforations at the end plates
axillary bud
where the petiole joins the stem
leaf
primary site of photosynthesis:
all have an epidermis/guard cells, internal parenchyma cells, and vascular tissue (veins) to transport photosynthate and water
petiole
stalk of the leaf
blade
round leaf structure
stoma (pl. stomata)
caused by turgor pressure
atmospheric gases can entire and water vapor can escape
potassium ions/water expansion regulate opening/closing
guard cell
present on bottom of epidermis
regulate exchange between atmosphere and mesophyll cells

ray
facilitate transverse movement across stem - secondary tissues that transport metabolic wastes to center of the stem
