Topic 6 - Inverse Square Law: Rate Of Photosynthesis

Question 1

What is the relationship between light intensity and the rate of photosynthesis?

Answer 1

Light intensity is directly proportional to the rate of photosynthesis

Greater light intensity results in more photons hitting chloroplasts, enhancing photosynthesis.

Question 2

What is the inverse square law in the context of light intensity?

Answer 2

Light intensity is inversely proportional to the square of the distance from the light source

As distance increases, light intensity decreases.

Question 3

If a lamp is 2 meters away from a plant, what is the light intensity compared to its original value?

Answer 3

The light intensity is 1/4 of its original value

This is calculated as 1/2^2 = 1/4.

Question 4

What happens to light intensity as the distance from the light source increases?

Answer 4

Light intensity decreases

This follows the principle of inverse proportion.

Question 5

Fill in the blank: The relationship between the rate of photosynthesis and distance from the light source is described as _______.

Answer 5

inverse proportion

This indicates that as one factor increases, the other decreases.

Question 6

What is the mathematical expression for light intensity in relation to distance?

Answer 6

Light intensity OC 1/distance^2

This represents the inverse square law mathematically.
