which of the following is not a factor that affects productivity? This is a topic that many people are looking for. star-trek-voyager.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, star-trek-voyager.net would like to introduce to you Factors That Affect the Rate of Photosynthesis Biology for All FuseSchool. Following along are instructions in the video below:
“One of the chemical reactions. That is fundamental to your life you should already know know all about the process. But if you are unsure watch our video on photosynthesis in this video. We are going to have a look at the factors that affect the rate of photosynthesis there are three main factors light intensity carbon dioxide concentration and also temperature these factors are called limiting factors light is essential for photosynthesis as it provides the energy to split the water and therefore enable carbon dioxide and water to react no light no photosynthesis increasing the light intensity increases the rate of photosynthesis until a point when the rate is at its maximum in fact plants spread out their leaves to maximize the amount of light falling on them and to ensure that lower leaves are not shaded by the ones above some woodland plants are known as shade plants because they can photosynthesize more efficiently in dim light than other species if there is insufficient carbon dioxide in the air then photosynthesis cannot occur at the maximum rate however just like us plants are sensitive to temperature too hot and they cannot photosynthesize too cold and their productivity slows down to zero this is because there are enzymes involved in photosynthesis and so above 40 degrees.
Celsius. The enzymes start to denature and so the rate of photosynthesis slows down. And then as it gets cooler. The enzymes move around more slowly and hence.
The rate of reaction drops different types of plants have different optimum temperatures for photosynthesis plants that live in colder climates have an optimum rate at a lower temperature these are the three main limiting factors. However there are some others such as chlorophyll concentration water and pollution farmers and horticulturists can use the knowledge of these limiting factors to increase crop growth in greenhouses. They can use artificial lights to extend the daylight hours or increase the light intensity they can increase the concentration of carbon dioxide by burning paraffin lamps and they can control the temperatures inside the greenhouse. Unsurprisingly many crops such as tomatoes.
And lettuce give much higher yields. When grown in greenhouses another fantastic bonus of photosynthesis is that because it needs carbon dioxide we can pump waste carbon dioxide from our factories straight into greenhouses one man s waste is another man s well plants treasure so from this video you should know that carbon dioxide concentration light intensity and temperature are the main limiting factors that affect the rate of photosynthesis. But remember there is a maximum rate that can be achieved. ” .
