B1.4.4 Interaction Of Limiting Factors

Question 1

Limiting factors of phptosynthesis

Answer 1

Carbon dioxide
Temperature
Light intensity

Question 2

Simply put how to measure rate of photosynthesis

Answer 2

Measuring how much oxygen or glucose a plant makes in a given time.

Question 3

An alternative to measuring rate of photosynthesis

Answer 3

Glucose is used to produce new cells, so you can also calculate the increase in biomass in a given time

Question 4

How does light intensity affect rate of photosynthesis

Answer 4

The higher the light intensity, the faster the rate of photosynthesis.
This continues until photosynthesis reaches its maximum rate

Question 5

How does carbon dioxide affect the rate of photosynthesis

Answer 5

The greater the co2 concentration, the faster the rate of the reaction
Most commonly the limiting factor since the atmosphere only contains about 0.04% of it

Question 6

How does temp affect the rate of photosynthesis

Answer 6

The higher the temp, the faster the reactions occur.
However, if temp too high, the enzymes will denatures so reactions will stop

Question 7

What is the inverse square law

Answer 7

When you double the distance of the light source, the light intensity decreases by a factor of 4

Question 8

Formula for rate of photosynthesis

Answer 8

R=1/t

Question 9

Formula for light intensity

Answer 9

1/d^2

Question 10

Investigating fate of photosynthesis

Answer 10

Elodea.
The volume of gas.given off per minute
Counting bubbles produced per min
