PLANT STRUCTURE AND FUNCTION (THE LAST CHAPTER!!)
PLANT STRUCTURE AND FUNCTION • MONOCOTS VS DICOTS
PLANT STRUCTURE AND FUNCTION • ORGAN SYSTEMS • ROOT SYSTEM • FUNCTION?? • SHOOT SYSTEM • MADE UP OF STEMS AND LEAVES • FUNCTIONS??
PLANT STRUCTURE AND FUNCTION • ROOTS • FUNCTIONS?? • TYPES?? • TAPROOT VS FIBROUS • ROOT HAIRS • FUNCTION??
PLANT STRUCTURE AND FUNCTION • STEMS • FUNCTION?? • NODES VS INTERNODES?
PLANT STRUCTURE AND FUNCTION • LEAVES
PLANT STRUCTURE AND FUNCTION • MAJOR TYPES OF PLANT CELLS • PARENCHYMA CELLS • COLLENCHYMA CELLS • SCLERENCHYMA CELLS • TRACHEIDS AND VESSELS* • SIEVE-TUBE CELLS AND COMPANION CELLS*
PLANT STRUCTURE AND FUNCTION • MAJOR TYPES OF TISSUES • THREE TYPES • DERMAL • GROUND • VASCULAR • XYLEM VS PHLOEM
PLANT STRUCTURE AND FUNCTION • PLANT GROWTH • PRIMARY VS SECONDARY • PRIMARY GROWTH IS VERTICAL • SECONDARY GROWTH IS HORIZONTAL • SECONDARY GROWTH IN WOODY DICOTS IS UNIQUE
PLANT STRUCTURE AND FUNCTION • SECONDARY GROWTH IN WOODY DICOTS • UNIQUE STRUCTURES • VASCULAR CAMBIUM • CORK CAMBIUM • CORK • PRIMARY VS SECONDARY XYLEM**
PLANT STRUCTURE AND FUNCTION • REPRODUCTION
PLANT STRUCTURE AND FUNCTION • POLLINATION • TWO TYPES • WIND VS ANIMAL • MAJOR STRUCTURES TO REMEMBER • OVULE develops into the seed • COTYLEDON “SEED LEAF”; may become the embryonic first leaves of a seedling • RADICLE is the embryonic root of the plant, and grows downward in the soil • HYPOCOTYL primary organ of extension of the young plant and develops into the stem • EPICOTYL embryonic shoot above the cotyledons. In most plants the epicotyl will eventually develop into the leaves of the plant • SEED COAT
PLANT STRUCTURE AND FUNCTION • OVARY DEVELOPS INTO A FRUIT
PLANT STRUCTURE AND FUNCTION • GERMINATION**
PLANT STRUCTURE AND FUNCTION • VEGETATIVE REPRODUCTION VS VEGETATIVE PROPAGATION
PLANT STRUCTURE AND FUNCTION • TROPISM VS PERIODISM • PHOTOTROPISM • GROWING TOWARDS LIGHT (SLIGHTLY MISLEADING) • PHOTOPERIODISM • LONG-DAY VS SHORT DAY • ACTUALLY EFFECTBY HOURS OFDARKNESS
