Chapter Four: Plant Tissues Flashcards
four basic tissue types that make up gymnosperms and angiosperms
- meristems
- ground tissue
- dermal tissue
- vascular tissue
regions of active cell division
meristems
meristems contain ____ cells
undifferentiated
meristem that is located near the tips of shoots and roots in all plants
apical meristem
three types of primary tissue
- protoderm
- procambium
- ground meristem
the protoderm gives rise to the ____
epidermis
the procambium gives rise to the ___ and ___
primary xylem and primary phloem
the ground meristem gives rise to the ___ and ___
cortex and pith
pith is found in the central region of ____
monocots
apical meristems allow shoots and roots to ____; this is known as ____
lengthen
primary growth
located near older roots and shoots of woody dicots and gymnosperms
lateral meristems (cambia)
gives rise to secondary xylem and phloem
vascular cambium
gives rise to outer bark
cork cambium
lateral meristems allow shoots and roots in ___; this is known as ___
increase in girth
secondary growth
located at the base of grass plants, allows grass to regrow after being cut back
intercalated meristems
makes up the bulk of plant interior
ground tissue
3 cell types in ground tissue
- parenchyma
- sclerenchyma
- collenchyma
parenchyma cells have a ___ cell wall
thin
parenchyma cells function in ___, ___, and ___
cellular respiration, photosynthesis, and storage of metabolic products
sclerenchyma cells have a ___ cell wall and are ___ at maturity
thick
dead
sclerenchyma cells function to support ____ regions of plants; aka ___ support
non-growing
rigid
two different types of sclerenchyma
sclerids, fibers
collenchyma cells have a ___ cell
unevenly thick
collenchyma cells function to support growing regions of ___
shoots
a single layer of tightly packed cells covering plants
dermal tissue
waxy coating produced by epidermis of stems and leaves
cuticle
term for the wax that is produced by epidermis
cutin
