How does light intensity affect the rate of respiration?
Jsciencehelpneeded
In general, net respiration (Rnet) in plants increases as light intensity increases.

Higher 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.
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.
What is the testable question for light?
How does the intensity of light affect the rate of photosynthesis in plants?
At what light intensity do you expect there to be no net productivity?
No net productivity is expected at the compensation point, where the rate of photosynthesis equals the rate of respiration, typically occurring at low light intensities around 1-10% of full sunlight.
What are some of the factors that affect the rate of photosynthesis?
Factors that affect the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll and other pigments. Changes in any of these factors can influence the rate at which plants can convert light energy into chemical energy.
What light intensity would their be no net productivity?
The compensation point is the light intensity at which the rate of photosynthesis exactly matches the rate of respiration, resulting in zero net productivity. Below this threshold, the plant consumes more energy through respiration than it is able to produce through photosynthesis, leading to no net gain in biomass.
How does light intensity affect the rate of photosynthesis?
Light intensity directly affects the rate of photosynthesis in plants. As light intensity increases, the rate of photosynthesis also increases up to a certain point where it plateaus. This is because at low light intensities, the rate of photosynthesis is limited by the availability of light energy for the light-dependent reactions to occur.
What are three factors that affect the rate of photosysthesis?
Amount of CO2 available, light intensity and temperature, all effect the rate of photosynthesis.
What is the relationship between light intensity and photosynthetic rate?
The relationship between light intensity and photosynthetic rate is that if the intensity of the light is high then the rate of photosynthesis will increase. However the rate of photosynthesis will only increase to an extent after intensity of light reaches a certain point photosynthesis rate will stay still.
How does changing the light intensity effect photosynthesis and why?
Increasing light intensity generally increases the rate of photosynthesis up to a point where the plant reaches its light saturation level. Beyond this point, further increases in light intensity do not lead to a corresponding increase in photosynthesis. This is because the plant reaches a maximum rate of photosynthesis and becomes limited by factors other than light, such as temperature or carbon dioxide availability.
Environmental factor that can affect the rate of photosynthesis?
Light intensity is a key environmental factor that can affect the rate of photosynthesis. As light intensity increases, so does the rate of photosynthesis, up to a certain point where it plateaus. Other factors such as temperature and carbon dioxide concentration can also influence photosynthesis rate.
What are the 3 main factors that affect the rate of photosynthesis?
Light, carbon dioxide concentration, and temperature.
Which of the following does not affect photosynthesis rate of a plant?
intensity of lightIt is affected by temperature, pH , intensity of light . Other physical factors do not affect much
