Lab 6 quiz Flashcards
the most abundant cell type is
parenchyma
which cell lives at maturity with thin cell walls
parenchyma
functions of parenchyma include
storage, carbon fixation, and various roles in tissues like mesophyll and cortex.
collenchyma are ____ at maturity
living
collenchyma are [blank] (length) cells with [blank] (thin or thick) regions provinding [blank] (what type of support) support in growing areas
elongated, thickened, structural
which cell type is dead at maturity
schlenrenchyma
funciton for schlerenchyma
mechanical strength and stiffness
name of the stain used
tbo
type of cuts
transvers (cross section), tangential (anywhere but the middle), longitduinal (straight down the middle)
macroscelreids
long narrow stick like
osteosclereids
pointy ends, long in the middle
astrosclereids
star shaped
tricoschlereids
hair like
what was the raununculus acris
a mature root crosssection
what was observed in this Plasmodesmata in Diospyros endosperm
parenchyma
what organell could we not see in trifolium pratense
collenchyma, it had parenchyma, xylem/schlerenchyma, and phloem
what were we looking for in blast
schlerenchyma
the oak fibres were which type of cell type
schlerenchyma
Why do parenchyma cell walls in Trifolium thicken with age?
part of the plant’s natural process of maturation and structural adaptation.
thickening enhances overall structural integrity and support
purpose of sclerenchyma cells?
provide mechanical strength and rigidity to the plant. These cells have thick, lignified secondary walls and are typically dead at maturity, making them well-suited for supporting structures such as stems and other plant parts.
Why are the bast fiber cells of Linum not stained red unlike most fiber cells
they might not contain lignin, which typically reacts with certain stains to appear red
