Transport in plants
Photosynthetic product
Glucose stored in leaves
Palisade cells
Flowers through perforated ends of sieve plate cells of phloem to all tissue
Uses energy from respiration
Minerals
Uptake and transport
CO2 =carbon+ Dioxide H20 = hydrogen +14 other needed (NDK)
Root hairs
Diffusion /active transport
Distributed by xylem
Food storage
Modification of organs
Onion
Fleshy leaves store starch
Potato
Steam
Leaves store starch
Carrot
Tap root
Starch
Dicots
Carbon dioxide
Respiration
Mitochondria in palisade layer produce co2 as waste of respiration
stomato
Extra co2 from atmosphere diffuses
Water
Transpiration stream
Root Pressure
Root hair absorbs (increase area)
Pressure pushes water up xylem
Diffuses across cortex
Osmosis water enters root
Adhesion of water molecules
Water molecules stick to each other forming strong column
Cohension of water
Upward force created as h20 molecules attract each other
Cohension tension model
Continuously- transportation adhesion+ cohesion = Strong unbreakable column
Transpsuction froceortation of water from leaves = suction force
Water drain up xylem to replace lost h20
