B8.2 The rate of photosynthesis Flashcards
1
Q
Why does light affect photosynthesis?
A
Lots of light means chloroplast can absorb more energy and lead to an increase in photosynthesis
2
Q
Why does temperature affect the rate of photosynthesis?
A
A higher temperature leads to an increase of photosynthesis due to enzymes having more energy - but could also lead to enzymes becoming denatured
3
Q
Why is the carbon dioxide concentration rising at night?
A
Because in the dark a plant respires but doesn’t photosynthesise
4
Q
What is light intensity formula?
A
Light intensity is inversely proportional to 1/ distance ^ 2
