QUESTIONS WITH VERIFIED ANSWERS
/. spines - Answer-✅modified leaves
/.cork - Answer-✅Waxy cells produced in secondary growth that replace primary dermal
tissue.
/.dermal tissue - Answer-✅outer, protective tissue of plants
/.simple leaf - Answer-✅a leaf with a single blade
/.compound leaf - Answer-✅blade is divided into multiple leaflets
/.zone of cell division - Answer-✅Contains the apical meristems and its derivatives in
the root.
/.root hairs - Answer-✅extensions of root epidermal cells where most water absorption
takes place
/.apical meristems - Answer-✅divide to produce primary growth at the tips of roots and
stems, increase length
/.lateral meristems - Answer-✅secondary growth in woody plants, increases girth,
/.tap root system - Answer-✅consists of a single, large, vertical root; in eudicots
(EX. carrots and turnips)
/.Sclerenchyma - Answer-✅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 - Answer-✅location of primary growth in the shoot
/.vascular tissue - Answer-✅tissue that transports materials
/.vascular cambium - Answer-✅makes new xylem and phloem in secondary growth
/.primary growth - Answer-✅occurs in the youngest parts of the plants
, /.zone of elongation - Answer-✅responsible for most increase in length in primary
growth of roots

/.stolon - Answer-✅the runner of a strawberry plant, allow sexual reproduction
/.tracheids - Answer-✅thin tapered xylem cells
/.xylem - Answer-✅water conducting vascular tissue
/.bulb - Answer-✅underground stem for food storage and composed largely of leaf
layers
(EX. Onion)
/.meristems - Answer-✅embryonic tissues in growth areas
/.secondary growth - Answer-✅occurs in older parts of woody plants
/.fibrous root system - Answer-✅composed of a network of many, thin roots; in
monocots
/.ground tissue - Answer-✅composed mostly of parenchyma cells and does many jobs
in the plant
/.parenchyma - Answer-✅most unspecialized, lack secondary cell walls, flexible,
perform most metabolic jobs of plant
/.guard cells - Answer-✅form the stomata
/.stomata - Answer-✅allow gas exchange in leaves,
/.protoderm - Answer-✅primary meristem that produces dermal tissue
/.procambium - Answer-✅primary meristems that produce vascular tissue
/.cladophyll - Answer-✅photosynthetic stem
(EX. cacti)
/.stele - Answer-✅center of root containing vascular bundles
