I am investigating the effects of light on the .

So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy.¡¨ So this shows my prediction was correct for in my experiment and shown in my result table and graph the more light intensity there is on a plant the higher the rate of my photosynthesis will be.

Count bubbles of oxygen gas given off by elodea to determine the rate of photosynthesis.4.

(Effects of increased CO2 levels on plants and various ecosystems as a result of anthropogenic global change will be most interesting to observe!) Rosenzweig notes that, on a geographical scale, each of the other two requisites for photosynthesis, water and solar energy, are much more variable in their availabilities and more often limiting; moreover, AET measures the availability of both.

Effect of different colors of light on the rate of photosynthesis.

The light intensity will be changed for it is the only variable used in the experiment.

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.

Hypothesis:Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose....

Investigate the effect of light on seed germination.

It is true that the brighter the light, the greater the rate of photosynthesis.

Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.

(However, plants generate daily variations in concentrations of oxygen and carbon dioxide through their photosynthetic and respiratory activities.) Thermal profiles at midday in corn fields at various stages of growth are shown in Figure 4.4, demonstrating the marked reduction in ground temperature due especially to shading.

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

  • Time (min.) Rate of Photosynthesis

    If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.

  • How does the level of light affect the rate of photosynthesis

    How does light intensity and duration affect the rate of photosynthesis?

  • What is the effect of light intensity on the rate of photosynthesis

    In this experiment I will investigate how sodium hydrogen carbonate affects the rate of photosynthesis.

Effect of Light Intensity on Photosynthesis

Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).

Effect of Light Intensity on Photosynthesis by …

When photosynthesis takes place, plants use the suns energy to combine carbon dioxide from the air with water from the soil to create glucose (a carbohydrate)....

Light Intensity and Photosynthesis by Moesha Grant on …

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

Photo - Light Intensity | Photosynthesis | Glasses

Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis.

What is the effect of light intensity on photosynthesis?

I believe this will happen because when the light source is nearer to the plant more of the plants surface area is coming in to contact with the light from the desk lamp therefore more photosynthesis will occur which will mean more oxygen will be produced which will create more bubbles....

Effects Light has on the rate of Photosynthesis ..

6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....

Measuring the rate of photosynthesis - Science and …

Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.
