Question

name two factors that affect photosynthesis and explain?how they effect

Answer 1

please check the writing bcoz I brought it from my bro
only writing problem nothing else...

Answer 2

Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.

light intensity: Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.

carbon dioxide concentration : Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.
If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.

temperature: If you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones above.

In practice, any one of these factors could limit the rate of photosynthesis.
