Transpiration

Adaptation to reduce transpiration

• Broader leaves

• Stunted growth

• More stomata

• Narrow leaves

The plants transpire more in

• high humid conditions

• low temperature

• reduced pressure

• calm day

The rate of transpiration increases with

• High atmospheric CO2 level

• Low water content of leaf

• Shedding of leaves

• Dry air

The rate of transpiration decreases with

• high temperature

• high water content of leaf

• closure of stomata

• intensity of sunlight

What is being produced during photosynthesis?

• sugar and oxygen
• sugar and carbon dioxide
• glucose
• gases

What gas is TAKEN IN during photosynthesis?

• argon
• nitrogen
• oxygen
• carbon dioxide

What is transpiration?

• Excess water being released from the aerial parts of plants in the form of water vapor

• Excess sugar being released from the leave

• The way a plant makes its food

• When the plant uses sugar for energy

Water transported from stems to leaves through what?

• xylem

• phloem

• stems

• roots

Which of the following indicates the pathway of water through a plant?

• root hair cell --> xylem --> Mesophyll --> substomatal space --> stomata

• substomatal space -- > stomata --> root hair cell --> xylem --> Mesophyll

• xylem --> stomata --> root hair cell --> Mesophyll --> Substomatal space

Select all of the environmental factors that would increase transpiration.

• Increased humidity

• Increased wind speed

• Increased temperature

• Decreased surface area
