A | B |
stems | serve as framework and support to position leaves |
leaves: | primary location for photosynthesis |
meristem | give rise to all other cells of plant |
ground meristem | produces ground tissue |
protoderm | produces epidermis |
procambium | produces primary vascular tissue |
lateral meristems | secondary growth initiated by |
cork cambium | cork cells in bark of woody plants (outer bark) |
vascular cambium | secondary vascular tissue |
PLANT TISSUES AND CELL TYPES=A. 3 basic tissues | dermal tissue, ground tissue, vascular tissue |
guard cells | paired cells flanking a stoma |
trichomes | hair like epidermal outgrowths |
root hairs | single cells found near root tips |
ground tissue | primarily parenchyma cells |
parenchyma cells | most abundant cells of primary tissues |
collenchyma | living at maturity (usually long-lived) |
sclerenchyma | thick, tough secondary walls |
lignin | highly branched polymer that reinforces structure |
fibers | long, slender, usually grouped in strands |
sclereids | variable in shape; often branched; single or in groups |
