Photosynthesis

Question 1

Photosynthesis

Answer 1

Process by which plants make there own food

Question 2

Chlorophyll

Answer 2

Traps light energy and combines it with carbon dioxide and water to produce glucose

Question 3

roles of photosynthesis

Answer 3

Make food for plant and animal
Removes carbon dioxide from air

Question 4

chemical equation for photsynthesis

Answer 4

6CO2+6H2O+Light —> C6H 12O6+6O2

Question 5

Requirements of photosynthesis

Answer 5

Carbon Dioxide
Water
Light energy
Chlorophyll

Question 6

(stage one ) Pathway 1 , light dependant stage

Answer 6

Light energises electrons in chlorophyll
Energised electrons transport to electron acceptor
e- move allong etc releasing energy and adp+p forming atp
then e- return to chlorophyll

Question 7

photolysis

Answer 7

water split by light energy

Question 8

water split by light energy

Answer 8

photolysis

Question 9

products of photolysis

Answer 9

H+ions
Oxygen

Question 10

Where is O2 created?

Answer 10

Created in the light stage and is waste product , released into the atmosphere or used by the leaf in respiration

Question 11

(stage 2) Pathway 2 , light dependant stage

Answer 11

Photolysis
NADP+ and e- create NADP-
NADP-and H+ create NADPH
Produce ATP and NADPH for the dark stage

Question 12

Stage 2 , Dark Stage

Answer 12

Takes place in stroma of chloroplasts
NADPH supplies H+,
Then reduces to NADP- , supplies e-

Question 13

Factors that effect Dark Stage ( Calvin Cycle )

Answer 13

Temperature and PH

Question 14

Distinguish between light and dark stage

Answer 14
