Transport In Plant

Transports water and minerals up from root to other parts of plant

Transport sucrose and ammino acids up and down the plant

-Xylem made of many hallow dead cells joined end to end -End walls of cells have disappeared so long open tube formed -Xylem vessel run from root of plant right up through stem,branch out into every leaf -Xylem vessel contain no cytoplasm no nucleus -Walls made of celluose and lignin

water moves by osmosis from high water potential in soil to low water potential in root hair cells through semi permeable membrane

Loss of water from leaves by evaproution of water at surface of mesophyll cells followed by loss of water vapor through stomata by diffusion

Water from xylem vessels in leaf will travel to cells by osmosis to replace it

√Constant uptake and transport of mineral ionse √Provide water to keep cells turgid to support upward growth of plant √Provide water to photosynthesize cells in leaves to conduct photosynthesis √Keep leaves cool by evaporative cooling

Transpiration increases as increasing temperature Light Intensity increase so transpiration increase Humidity higher so less watery will evaporate from leaves Wind speed increase so transpiration increase

Translocation: movment of sucrose and amino acids in phloem from regions of production to region of storage Phleom: transport sucrose and ammino acid up and down the plant according to seasonal changes in summer and spring from leaves to all plant parts while in winter from root to all plant parts

Group of specialized tissues the xylem and phloem that transport water dissolved salts and food throghout plant
