BIOL 1407 LECTURE EXAM 1 (YODER)
spines - Correct Answers -modified leaves
cork - Correct Answers -Waxy cells produced in secondary growth that replace primary
dermal tissue.
dermal tissue - Correct Answers -outer, protective tissue of plants
simple leaf - Correct Answers -a leaf with a single blade
compound leaf - Correct Answers -blade is divided into multiple leaflets
zone of cell division - Correct Answers -Contains the apical meristems and its
derivatives in the root.
root hairs - Correct Answers -extensions of root epidermal cells where most water
absorption takes place
apical meristems - Correct Answers -divide to produce primary growth at the tips of
roots and stems, increase length
lateral meristems - Correct Answers -secondary growth in woody plants, increases girth,
tap root system - Correct Answers -consists of a single, large, vertical root; in eudicots
(EX. carrots and turnips)
Sclerenchyma - Correct Answers -plant cells with rigid/thick cell walls containing lignin,
give support in areas that aren't growing, 2 forms (fibers in bundles and sclereids)
terminal bud - Correct Answers -location of primary growth in the shoot
vascular tissue - Correct Answers -tissue that transports materials
vascular cambium - Correct Answers -makes new xylem and phloem in secondary
growth
primary growth - Correct Answers -occurs in the youngest parts of the plants
, zone of elongation - Correct Answers -responsible for most increase in length in primary
growth of roots
vessel elements - Correct Answers -wider xylem cells with perforated ends
tendril - Correct Answers -leaf modification for clinging
stolon - Correct Answers -the runner of a strawberry plant, allow sexual reproduction
tracheids - Correct Answers -thin tapered xylem cells
xylem - Correct Answers -water conducting vascular tissue
bulb - Correct Answers -underground stem for food storage and composed largely of
leaf layers
(EX. Onion)
meristems - Correct Answers -embryonic tissues in growth areas
secondary growth - Correct Answers -occurs in older parts of woody plants
fibrous root system - Correct Answers -composed of a network of many, thin roots; in
monocots
ground tissue - Correct Answers -composed mostly of parenchyma cells and does many
jobs in the plant
parenchyma - Correct Answers -most unspecialized, lack secondary cell walls, flexible,
perform most metabolic jobs of plant
guard cells - Correct Answers -form the stomata
stomata - Correct Answers -allow gas exchange in leaves,
protoderm - Correct Answers -primary meristem that produces dermal tissue
procambium - Correct Answers -primary meristems that produce vascular tissue
cladophyll - Correct Answers -photosynthetic stem
(EX. cacti)
stele - Correct Answers -center of root containing vascular bundles
phloem - Correct Answers -vascular tissue that conducts sugar
