7. PLANT STRUCTURE AND FUNCTION
LEAVES

8. PLANT STRUCTURE AND FUNCTION
MAJOR TYPES OF PLANT CELLS
PARENCHYMA CELLS
COLLENCHYMA CELLS
SCLERENCHYMA CELLS
TRACHEIDS AND VESSELS*
SIEVE-TUBE CELLS AND
COMPANION CELLS*

9. PLANT STRUCTURE AND FUNCTION
MAJOR TYPES OF TISSUES
THREE TYPES
DERMAL
GROUND
VASCULAR
XYLEM VS PHLOEM

10. PLANT STRUCTURE AND FUNCTION
PLANT GROWTH
PRIMARY VS SECONDARY
PRIMARY GROWTH IS VERTICAL
SECONDARY GROWTH IS HORIZONTAL
SECONDARY GROWTH IN WOODY DICOTS IS UNIQUE

11. PLANT STRUCTURE AND FUNCTION
SECONDARY GROWTH IN WOODY DICOTS
UNIQUE STRUCTURES
VASCULAR CAMBIUM
CORK CAMBIUM
CORK
PRIMARY VS SECONDARY
XYLEM**

12. PLANT STRUCTURE AND FUNCTION
REPRODUCTION

13. 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

14. PLANT STRUCTURE AND FUNCTION
OVARY DEVELOPS INTO A FRUIT

15. PLANT STRUCTURE AND FUNCTION
GERMINATION**

16. PLANT STRUCTURE AND FUNCTION
VEGETATIVE REPRODUCTION VS VEGETATIVE PROPAGATION

17. PLANT STRUCTURE AND FUNCTION HORMONES!!!!
Where Found in Plant
Major Functions
Auxin
Embryo of seed, young leaves, meristems of apical buds
Stimulates cell elongation; involved in phototropism, gravitropism, apical domincance, and vascular differentiation; inhibits abscission prior to formation of abscission layer; stimulates ethylene synthesis; stimualtes fruit development; induces adventitious roots on cuttings
Cytokinin
Synthesized in roots and transported to other organs
Stimulates cell division, reverse apical dominance, involved in shoot growth, delay leaf sequence
Ethylene
Tissues of ripening fruits, nodes of stems, senescent leaves and flowers
Stimulates fruit ripening, leaf and flower senescence, and abscission
Abscisic Acid
Leaves, stems, green fruit
Stimulates stomatal closure
Gibberellin
Meristems of apical buds and roots, young leaves, embryo
Stimulates shoot elongation, stimulates bolting and flowering in biennials, regulates production of hydrolytic enzymes in grains

18. PLANT STRUCTURE AND FUNCTION
TROPISM VS PERIODISM
PHOTOTROPISM
GROWING TOWARDS LIGHT (SLIGHTLY MISLEADING)
PHOTOPERIODISM
LONG-DAY VS
SHORT DAY
ACTUALLY EFFECT BY HOURS OF DARKNESS
