3.8 Photosynthesis Flashcards | Quizlet

Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all.

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

Naturally occurring food and fuel contain complex carbon-based molecules, chiefly derived from plant matter that has been formed by photosynthesis. The chemical reaction of these molecules with oxygen releases energy; such reactions provide energy for most animal life and for residential, commercial, and industrial activities.

factors can limit the speed of photosynthesis ..

The Plan In my experiment I am going to see how light affects the rate of photosynthesis.



Variables

Input - Light intensityis to be varied by increasing and decreasing
the distance from the light source to the plant

Output - The rate of photosynthesisis to be measured by counting the
bubbles of oxygen produced by the plant every two minutes, and
therefore finding the rate of photosynthesis

Control - The amount of water available to the Elodea will stay the
same level in the 400 cm3 beaker.

The rate of photosynthesis of a plant can be affected by more than a factor and by the apparent amount of light that get in touch with the plants. This rate can be controlled by the grower in not as much of a long period of time so as to attain the maximum speed of growth and larger yields of the plants.

N2 - Wheat is the second most important direct source of food calories in the world. After considerable improvement during the Green Revolution, increase in genetic yield potential appears to have stalled. Improvement of photosynthetic efficiency now appears a major opportunity in addressing the sustainable yield increases needed to meet future food demand. Effort, however, has focused on increasing efficiency under steady-state conditions. In the field, the light environment at the level of individual leaves is constantly changing. The speed of adjustment of photosynthetic efficiency can have a profound effect on crop carbon gain and yield. Flag leaves of wheat are the major photosynthetic organs supplying the grain of wheat, and will be intermittently shaded throughout a typical day. Here, the speed of adjustment to a shade to sun transition in these leaves was analysed. On transfer to sun conditions, the leaf required about 15 min to regain maximum photosynthetic efficiency. In vivo analysis based on the responses of leaf CO2 assimilation (A) to intercellular CO2 concentration (ci) implied that the major limitation throughout this induction was activation of the primary carboxylase of C3 photosynthesis, ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). This was followed in importance by stomata, which accounted for about 20% of the limitation. Except during the first few seconds, photosynthetic electron transport and regeneration of the CO2 acceptor molecule, ribulose-1,5-bisphosphate (RubP), did not affect the speed of induction. The measured kinetics of Rubisco activation in the sun and de-activation in the shade were predicted from the measurements. These were combined with a canopy ray tracing model that predicted intermittent shading of flag leaves over the course of a June day. This indicated that the slow adjustment in shade to sun transitions could cost 21% of potential assimilation.

Even though in the process of photosynthesis, there are only small portion of water the plant can be absorbed and can be used in the process. If there is a lack of water, it can really affect the rate of the plant’s photosynthesis. This event can happen because the if the plant had a low amount of water, the stomates on the leaves will eventually close up and will result to the prevention of the waste gases and other toxic chemical’s release. The shutting down or closing up of the stomates of the leaves will surely slow down the photosynthesis from occurring and in some cases, it might lead to a stop.

For that reason, you should supplement CO2 in the existing amount in the air because it will result to speeding up of the photosynthesis and will also result in a rapid growth of the plants. In the experiments conducted, it was also shown that CO2 is another factor that helps the cannabis put up with higher room temperatures (up to 95 degrees F) with only a small impinge on the rate of photosynthesis.
