Gas Exchange Leaf Of Thw Plant Flashcards
1
Q
What diffuses in during the day
A
The co2 difffuses into the leafy through stomata and o2 diffuses our
2
Q
What diffuses in during the night
A
As no respiration is taking place 02 diffuses in and co2 diffuses our
3
Q
How is leaf adapted for gas exchange
A
Extremely thin so no cell far away from external air source
May stomata so gas exchange can take place and no cell far from the stomata
There are many air spaces integrated so readily has exchange can take place
Large surface area of mesophyll cell so that the gas exchange is more rapid
4
Q
What are stomata
A
Tiny pores which allow co2 to enter so can be used for photosynthesis controlled by guard cels they can close in order to conserve water
