Plant Exchange

Question 1

Respiration

Answer 1

C6H12O6 + 6O2 —–> 6CO2 + 6H2O

glucose + oxygen —-> carbon dioxide + water

Question 2

Photosynthesis

Answer 2

6CO2 + 6H2O —-> C6H12O6 + 6O2

carbon dioxide + water —-> glucose + oxygen

Question 3

During the Day

Answer 3

plants respire and photosynthesise
photosynthesis happens at a faster rate
net users of CO2

Question 4

During the Night

Answer 4

plants respire but do not photosynthesis as there is no light
net producers of CO2 which must be removed

Question 5

Where does gas exchage happen?

Answer 5

every part of the ‘body’ that needs O2 and CO2

every leaf can exchange gas with the environment

Question 6

gas phase

Answer 6

quick diffusion

exchange gas with the air around them by diffusiob

Question 7

short diffusion pathway

Answer 7

fast

Question 8

Leaf Adaptations

Answer 8

Stomata

Air Spaces

Question 9

Stomata

Answer 9

dotted on leaves for a short diffusion path to every cell

Question 10

Air Spaces

Answer 10

gives massive surface area for diffusion of gases into cells
