Answer 14

Stomata

Question 15

Why do we get stitches?

Answer 15

From a build up of lactic acid

Question 16

Why do plants use glucose?

Answer 16

For:-
- Respiration
- Storage
- Seeds
- Celluslose
- Protien Synthesis

Question 17

Whats the indepenent variable of the RP

Answer 17

Light intensity

Question 18

Whats the depenent variable of the RP

Answer 18

Rate of photosythesis

Question 19

Whats the control variable of the RP

Answer 19

Any from ;-
-time
-temp
-type of plant
-CO2 concentation

Question 20

Describe the light intensity graph

Answer 20

As the light intensity increases the rate of photosynthesis steadly increases and then slowly becomes a constant rate..

Question 21

Describe a carbon dioxide graph

Answer 21

As the carbon dioxide increases the rate of photosynthesis increases sharply and then slows to a constant rate

Question 22

Describe a temperature graph

Answer 22

As the temp increases the photosynthesis increases sharply but the falls steeper and slows to a complete stop.
