Transport in Plants
Phloem
Made of Living Cells
Thin Cell Wall
Cell Wall is made of Cellulose
Permeable Cell Wall
Only Cytoplasm Lining
Transports Food
Transports food to Growing Parts & Storage Organs
Can transport food up and down
Tissue contains companion cells
Transpiration and Translocation
Transpiration is the water loss from vapor from leaves
Water vapor evaporates from the surface of mesophyll cells into the air spaces then diffuses out from the stomata
Temperature and wind speed affect the rate of water loss through transpiration and humidity
Translocation is the movement of sucrose and amino acids in phloem from sources to sinks
Sources are parts of the plant that release sucrose or amino acids
Sinks are parts of the plant that use and store sucrose and amino acids
Xylem
Dead Cells
Thick Cell Walls
Cell walls are made of Lignin
Water Uptake
Root Hair Cells absorb water through Osmosis and Active Transport
Their large surface area increase the rate of water uptake and mineral ions
