, Plant Tissues
Summary :
TemporaryTissue
:
-
meristematic tissue
·
constantly dividing
can be anything
·
can cause lateral or apical growth
·
located at buds ; stem a root tips
·
Permanent Tissue :
-
Ground tissue
·
btw .
Vasculara dermal tissue
makes up bulk of plant
types parenchyma (gas exchange) ; Collenchyma; Schevenchyma (both strength a
support
·
:
-
dermal tissue
make up outer layer
·
outer layer can be covered by a waxy layer-cuticle
·
adaptations ) root hairs TSA :
:
·
2)Stomata : pores for transpiration
3) trichomes :
hairs on leaves/stems
vascular tissue
-
·
transports water a nutrients
2
types 1) Xylem water a minerals
:
:
2) phloem : Vitamins (food)
·
sit in vascular bundles
Mevistematic Tissue
undifferentiated ; contains actively dividing cells to form other
issue
·
dense cytoplasm
apical meristems : buds & tips ; taller longer
grow or
thin wall
lateral meristems :
woody trees & plants ; grow wider
⑳ large nucleus
·
Characteristics of Meristematic Tissue
Roots Buds
Spherical/polygonal cells backing of many
&
1. small ,
: close cells
.
2 Small labsent vacuoles : no rigiditybo it prevents rapid division
.
3 large cytoplasma nucleus :
undiff cells have fewarganelles. Efficient division
torn/dry epidermis
Dermal Tissue :
↑
covers plant. Herbaceous -
epidermis ; woody-periderm
·
Characteristics of Dermal Tissue
1.
layer of cells covering plant surface barrier
:
to fungi a pathogens
2
. thin a transparent Lets :
light in for photosynthesis
. Trichomes
3 Chairs) project from surface :
trap water
.
4 root hairs (elongations of roof) :
maximise TSA for more absorption of water a minerals
