Transport process
Photosynthetic products
glucose stored in leaves
palisade cells
Starch
sieve plate cells of phloem to all tissues
uses energy from respiration
Carbon dioxide
Stomata
Found upside of the leaves
acts like pores
Carbon dioxide enter for photosynthesis
allows oxygen
Waste products to leave
Respiration
carbon dioxide as waste of respiration
Food storage
Modification of organs
onion
low permeable to air
starch
potato
high water content
Starch
carrot
dicots
Starch
root shape
Water
Transpiration stream
Cohesion tension of water
moves up to xylem
inside cellular leaf
saturates cellulose microfibrils
cohesion of water
water evaporates through stomata
creates negative pressure
root pressure
transverse osmotic pressure
occurs in xylem of vascular plants
transpiration low during day
diffusion across cortex
Adhesion of water molecules
water molecules stick to form strong column
minerals
uptake and transport
diffusion transport
distribution of xylem
nutrients proceed
