primary growth

vertical growth

apical meristem (shoot and root)

zone of high cell division (primary growth)

stem

...

node

internode

...

epidermis

leaf surface that contains tiny hairs (trichomes)
made of compact epidermal cells covered by waxy layer (cuticle)

parenchyma

...

collenchyma

...

sclerenchyma

...

vascular bundle

...

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

spine

tendril

...

tuber

rhizome

corm

...

bulb

...

root

...

secondary growth

lateral growth of plant

cork

...

wood

...

ray

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

pith

central portion of the stem made of parenchyma cells
