B1.4 - Photosynthesis

Question 1

where do photosynthesis occur

Answer 1

photosynthesis takes place inside the chloroplasts. the chloroplasts contain chlorophyll absorbs the light from the sun

Question 2

what is the equation for photosynthesis

Answer 2

carbon dioxide + water —-> glucose + oxygen

Question 3

what is the number equation for photosynthesis

Answer 3

6C02 + 6H20 —-> C6H1206 +602

Question 4

what is an endothermic reaction

Answer 4

energy going into the reaction

Question 5

what are the stages of photosynthesis

Answer 5

1) light from the sun, carbon dioxide diffused from the air, water from the soil.
2) chlorophyll in the leaves.
3) glucose for biomass and energy, oxygen released as a by product

Question 6

what do plants do with the glucose they make during photosythesis

Answer 6

they use it for respiration - to release enegy. they use it to make other sugars, starch and cellulose

Answer 11

used in cell growth and repair

Question 12

what is a limiting factor

Answer 12

a limiting factor is any factor that will slow down the rate of photosynthesis if there is not enough of it

Question 13

what factors limit the rate of photosynthesis

Answer 13

temperature, carbon dioxide concentration, light intensity, amount of water
