6 Plant tissues
Epidermal
Palisade
Mesophyll
Spongy
Mesophyll
Xylem
Pholem
Meristem
Function of
Epidermal
tissue
Covers
and
protects
leaf
Function of
palisade
mesophyll tissue
Site of
photosynthesis
Function of
spongy
mesophyll tissue
The site of
gas exchange
and
phtosynthesis
Function of
xylem
tissue
Transport of
water
and
dissolved
ions
Function of
Pholem
tissue
Transport of
Glucose
Function of
meristem
tissue
Dividing into cells at growing tips of
shoots
and
roots
Three plant organs
Leaf
Stem
Roots
Transpiration
Movement of
water
from the roots to the leaves eventually leaving the leaves via
evaporation
4 factors affecting the rate of transpiration
Temperature
Humidity
Air
movement
Light
intensity
Translocation
Movement of
sugars
from the leaves to the rest of the plant
Adaptation of
Xylem
tissue
Hollow tubes strengthened by
lignin
in the walls
Adaptation of
Pholem
tissue
Elongated cells with
pores
in the end cell walls to aid the movement of dissolved sugars.
Function of
stomata
and guard
cells
Controling gas exchange and
water
loss
