Q

Why does the rate of photosynthesis level off eventually regardless of further increases in light intensity?

A

because the maximum rate of photosynthesis has been reached by all the available electrons being excited

Q

What happens to the enzymes and stomata after the rate of photosynthesis’ max. is reached?

A

the enzymes become ineffective and the stomata begin to close, limiting water loss and entry of carbon dioxide
