Plant Form and Functions Flashcards
underground part of the plant
root system
above part of the plant
shoot system
first organ to appear when a seed germinates
primary roots
smaller roots that emerge horizontally from the primary root
secondary roots
secures and protects the root tip
root cap
the end of the primary root
root tip
an extension of plant epidermal cells in growing plant roots
root hairs
outer layer of cells that provides protection and helps in absorption
epidermis
serve as a storage area for reserved foods(in plants)
cortex
central region of the root
stele
controls water transport. can be found in stele
casparian strip
boundary between the cortex and the stele
endodermis
support, protect, and functionally assist phloem and xylem cells .function to facilitate and regulate new lateral root growth
Pericycle/Cambium
vascular tissue that transports food and water
Phloem
vascular tissue that transports water and has a one way flow
xylem
carries out basic metabolic functions and stores food and water. cortex and pith
ground tissue
transportation vessel phloem and xylem
vascular bundle
the location on a stem to which a leaf or branch is attached
node
the part of a plant stem between two notes
internode
located in the axle of a leaf. potential to form shoots
lateral bud
a protective tissue
epidermis
tissues that are originally able to regenerate the plant, increase growth
shoot tip
protects the outer layer of the shoot
epidermis
transport and store nutrients and provide support. located outside the ring
cortex
