2
How does carbon dioxide needed for photosynthesis get to the cells in the leaf?
through stomata
through the phloem
through transpiration
through the xylem
3

sunlight and minerals
10
Why can't the white parts of the variegated leaf photosynthesise?
it has no stomata
it has no chlorophyll
the white part has no cells
it's dead
11
How does water needed for photosynthesis get to the leaf?
through transpiration
through the xylem
through stomata
through the phloem
12
What is iodine solution used to test for?
glycogen
glucose
sucrose
starch
13
Which is the correct balanced chemical equation for photosynthesis?
6O2 + 6H2O → C6H1206 + 6CO2
6CO2 + 6H2O → C6H1206 + O2
6CO2 + 6H2O → C6H1206 + 6O2
6CO2 + 6O2 → C6H1206 + 6H2O
14
The bubbles/min were counted at different distances. What is the
dependent
variable?
number of bubbles
temperature
carbon dioxide concentation
the boiling tube
15
If a plant has poor growth, which mineral ion is it lacking?
nitrate
magnesium
potassium
phosphorus
16
What is the independent variable in this investigation?
number of bubbles
temperature
colour of bulb
distance
