Limited Factors for Photosynthesis

Question 1

Limiting factor

Answer 1

A factor that can affect the outcome of something happening

Question 2

Factors that affect photosynthesis

Answer 2

. Carbon dioxide
. Light
. Temperature
. Water
. Chlorophyll

Question 3

How does increasing the light affect the rate of photosynthesis?

Answer 3

As light increases, the rate of photosynthesis increases. Light continues to increase but the rate of photosynthesis remains the same. This means that another factor must be limiting.

Question 4

How does increasing carbon dioxide affect the rate of photosynthesis?

Answer 4

Initially, as carbon dioxide increases, so does the rate of reaction. However, after a certain point, increasing carbon dioxide concentration has no effect on the rate of reaction. This means that another factor must be limiting.

Question 5

How does increasing the temperature affect the rate of photosynthesis?

Answer 5

Initially, increasing the temperature increases the rate of reaction as the reactants and enzymes have more kinetic energy and collide more frequently. However, above optimum temperature, increasing the temperature decreases the rate of reaction. This is because enzymes begin to denature at temperatures above 37°C.

Question 6

Linear relationship

Answer 6

Represented by a straight line on a graph

Question 7

Directly proportional

Answer 7

If the line goes through the origin (0,0). As one variable increases the other variable increases by the same percentage.
