FranHigher light intensity usually increases the rate of photosynthesis, which in turn can lead to higher levels of oxygen being produced. This can stimulate cellular respiration in some organisms as they use oxygen to generate energy. However, excessive light intensity can also damage cells and reduce respiratory activity.

What effects the rate of respiration in plants?
Factors that affect the rate of respiration in plants include temperature, availability of oxygen, and the presence of sugars or other organic compounds that can be broken down for energy. Light intensity and the plant's metabolic activity can also influence respiration rates.
How does light intensity and the rate of photosynthesis relate to the position of the sun?
The angle and intensity of sunlight affect the rate of photosynthesis in plants. Plants positioned in direct sunlight receive higher light intensity and thus have a higher rate of photosynthesis compared to shaded plants. The position of the sun in the sky also determines the light angle and intensity that plants receive, influencing their photosynthetic rate.
What are the three factors that affect the rate of photosynthesis?
Temperature, light intensity, and the availability of water. Is this from Miller & Levine Bio p.241??
How does the rate of photosynthesis respond to changes in light intensity?
It directly increases along with the growth in intensity of the light
Is it true that an increase in light intensity will not increase the rate of photosynthesis?
No, that is not true and increasing light intensity increases the photosynthetic rate, to a point. The saturation point is reached when the reactions in the reaction center have reached top speed and any more light intensity will not increase the rate of photosynthesis.
