Plant Physiology Vocab (10-3-14)

water/nutrients diffuse to cells, needs water for fertilization

has transport system for water/nutrients -> taller

don't need water for fertilization

seed plant; cone instead of fruit

seed plant; flowers develop into fruit

angiosperm; one cotyledon, scattered primary vascular bundles in stem

angiosperm; two cotyledons, ring shaped primary vascular bundles in stem

repeating modules of nodes, internodes, and buds

repeatedly branching root segments

uneven cell division causes one cell to have less cytoplasm than the other

groups of undifferentiated cells that continue to divide and create new tissues and organs throughout the life of a plant (Intermediate growth)

allow plants to lengthen (Primary growth)

causes plants to thicken (Secondary growth)

outer covering (epidermis), single cell layer; trichomes and leaf hairs

most of the body, between dermal and vascular tissues. for storage, support, and photosynthesis

Ground tissue; parenchyma cells, living at maturity, thin primary cell walls, large central vacuole; photosynthesis, storage, wound healing, asexual reproduction

Ground tissue; collenchyma cells, living at maturity, thick cell wall

Ground tissue; fibers (long cells grouped in bundles for rigid support) and sclereids (round cells with hard shells), dead at maturity, thick secondary walls

plumbing (transports water/nutrients from production/intake to other areas)

Vascular tissue; transports water and mineral ions from roots to rest of plant, dead at maturity

Xylem; ancient, tapered but no hole passes through pits (diffusion)

Xylem; angiosperms, long and tubular, open at both ends (pipes)

Vascular tissue; transport carbs from sources to sinks, alive at maturity, cell walls have pores (plasmodesmata) that connect (Sieve plates)
