cool-season plant a plant with an optimum growth temp of 60-75f solanaceae the nightshade family drupe a dry, fleshy fruit with outer thin skin, fleshy middle, and a hard center pit epigynous describes an inferior ovary arrangment pod dehiscent dry fruit that opens along 2 structures tracheid long thin cell with tapered ends involved in water conduction hypogenous describes a superior overy arrangement asteraceae the sunflower family stolon above ground stems that grow horizontally short-day plant a plant that flowers in responce to the lenthening nights of autumn warm-season plant a plant with an optimum growth temo. of 80-95f perenial a plant that repeats its life cycle indefinitely chloroplast a plastid containing chlorophyll; site of photosynthesis plasmodesmata intercellular cytoplasmic connection spongy mesophyll irregularly shaped parenchyma cells in lower portion of leaf microtubules lend support for cellular shape oligocentric crops center of origin, widely disersed; numerous secondary centers prokaryotic cell with no membrane enclosed organelles meristem a zone of active cell division sclereids irregular shaped sclerenchyma cells palisade mesophyll columnar parenchyma cells oriented perpendicular to leaf surface monocentric crop center of origin, widely dispersed; no secondary center apparent superior refers to sepals, petals and stamens attached below ovary pericycle outermost zone of stele meristematic; from which lateral root arise golgi apparatus membranous sacs that package proteins for secretion in vescles periderm stem tissue composed of cork cells smooth endoplasmic reticulum organelle that serves as the site of packaging and transport of lipids pepo fruit with hard rind that develops from inferior ovary endemic crop origin was a limited area without spread or dispersal inferior refers to sepals, petals and stamens attached above ovary eukaryotic cell with membrane enclosed organelles fibers long, staight sclerenchyma cells found in xylem for support casparian strip a waterproof corky layer in the endodermis of roots bundle sheath tightly packed cells surrounding vascular tissue in leaf long-day plant a plant that flowers in response to shortening nights of spring follicle dehiscent, dry fruit that opens along one structure tendrils used by climbing plants for attachment and support ribosome cell organelle responsible for protein synthesis bulb compressed underground stem with leaf scales biennial a plant that requires 2 years to complete its life cycle stipules paired appendages found at base of petiole shrub plants with multiple stems originating at the ground sieve tube long, thin cells with tapered ends involved in sugar conduction samara a one-seeded fruit with winged appendages formed from pericarp soil mixture of 25% air, 45% minerals, 25%water, 5% organic matter soil properties color, texture, stucture, chemistry, depth soil structure the arrangement of the mineral particles soil structure is affected by soil texture, organic matter-humus, root penetration organic matter humus trnspiration movement of water
