Question Answer
What are stomataTiny holes that are located on the underside of a leaf and lose water through transpiration
What are guard cellsThey surround stomata and allow the stomata to open and close
What gas is taken in by plants for photosynthesisCO2
What gas is taken in by plants for respirationO2
What is xylemThey transport water + minerals
What is phoelemThey transport food- sugars
Where are xylem located in the root and what is their purposeIn the middle which allows flexibility
Where are xylem located in the stem and what is their purposeAround the edge to give support
What is transported in the phoelem to other parts of the plantSucrose + amino acids
What is transported in the xylem from the roots to other parts of the plantWater + mineral salts
How is water absorbedRoot hairs increase surface area so more water is absorbed by osmosis
How are minerals absorbedInto roots by active transport
What is transpirationEvaporation of water from the stomata.
What factors affect transpirationTemperature, wind speed and humidity
How does temperature affect transpirationHigher the temperature, quicker the transpiration
How does wind speed affect transpirationHigher the wind speed, quicker the transpiration
How does humidity affect transpirationHigher the humidity, slower the transpiration
