Question 1

Is photosynthesis endothermic / exothermic

Answer 1

endothermic

Question 2

what is the word equation for photosynthesis

Answer 2

carbon dioxide + water => glucose + oxygen

Question 3

what is the symbol equation for photosynthesis

Answer 3

6CO2 + 6H2O => C6H12O6 + 6O2

Question 4

how are leaves adapted (3)

Answer 4

1) leaves are broad so large SA
2) leaves are thin so the diffusion distances are short
3) they contain chlorophyll to absorb light

Question 5

what are the 4 limiting factors for photosynthesis

Answer 5

light, temp, CO2 concentration and chlorophyll levels in the leaf

Question 6

light intensity equation

Answer 6

light intensity = 1 / distance2

Question 7

how do plants use glucose (5)

Answer 7

use the glucose produced during photosynthesis for respiration, to convert into insoluble starch for storage, to produce fats or oils for storage, to produce cellulose to strengthen cell walls, and to produce amino acids for protein synthesis.
