transpiration
the movement of water theough a plant
xylem
transports watet and minerals
xylem features
-made of dead cells
-lignin strengthens the walls
transpiration increases with
high temp
low humidity
wind
light intensity
translocation
the movement of dissolved sugars within a plant
phloem fewtures
-substances move up ans down
-sieve plates (pores)
-made of living cells
photosynthesis
6co2 + 6h20 = c6h1206 + 602
uses of glucose
respiration
cellulose (cell walls)
protein synthesis
storagw (cobverted into starch because it is insoulble)
seeds (fat and oils)
fruit
signs of plant vitus
stunted growth
areas of decay or discolouration
abnormal growths
presence lf peats
tmv
mosaic pattern of discolouration
rose black spot
purple black spots on leaves
discolouration
less chlorophyll - less light absorbed - less photosynthesis - stunted growth
