11.1 overview of photosynthesis

Question 1

what 5 conditions are needed for photosynthesis?

Answer 1

1- sunlight
2- CO2
3- H2O
4- chlorophyll
5- temperature

Question 2

which 3 are limiting factors of photosynthesis?

Answer 2

1- temperature
2- CO2
3- sunlight (light intensity)

Question 3

how does leaf arrangement & structure maximise photosynthesis? (9)

Answer 3

light
- large SA
- arrangement of leaves
- transparent cuticle & epidermis
- long & narrow mesophyll cells with lots of chloroplasts

CO2
- numerous stomata -> short diffusion distance
- stomata open & close
- air space for rapid diffusion distance
- thin -> short diffusion distance
- vascular bundle network

Question 4

which 2 structures in the chloroplasts are for light-dependent & light-independent reactions?

Answer 4

thylakoid - light-dependent
stroma - light-independent
