Energy transfers - Compensation point

What two energy related functions are performed at the same time in plants?

Respiration and photosynthesis

Are photosynthesis and respiration performed at the same rate?

Sometimes but generally not

What two energy related functions are performed at the same time in plants?

Respiration and photosynthesis

Are photosynthesis and respiration performed at the same rate?

Sometimes but generally not

What is it called when the rate of photosynthesis matches the rate of respiration?

Compensation point

When does the compensation point occur?

At a particular light intensity when the net movement of O2 or CO2 is 0

How can we work out the compensation point?

Measure the rate at which oxygen is produced and the rate in which it is used at different light intensities

Typical compensation point graph.

What are the limiting factors in photosynthesis?

Light intensity, carbon dioxide concentration and temperature
