However higher intensity have a better effect on the rate of photosynthesis, as it manages to hit not only the top part of the plant but also the bottom leaves, maximizing the effects of photosynthesis to the plants potential. Farmers use the power of grow lights to control the photoperiod during the seasons where sunlight isn’t as strong and photoperiod is lower and to increase the rate of photosynthesis. There are different kinds of grow light and each of them has different function or a different effectiveness: • Incandescent; The incandescent light bulb is used to control photoperiod mostly. This because the majority of energy form released from the light bulbs is heat rather than light, and is therefore an inefficient light source. Also because this light bulb releases mostly heat it must be placed at a correct distance from the plant, otherwise it might cause the plant to burn.
So it needs to pair up with other pigments that captures the wavelengths of light that chlorophyll misses especially the blue spectra and another function of these other pigments is to protect the leave from UV damage, an example for this kind of pigment is Xanthophyll. The reason why plant leaves are green is because the leave absorbs all the wavelengths of light except the green ones and the reflection of green is what we
The variation of the concentration of sodium bicarbonate will have an effect on the rate of photosynthesis of spinach (Spinacia oleracea). In this experiment it was ultimately found that the 95% confidence interval bars of treatment group 1 and treatment group 2 overlap, however none of the treatment groups overlap with each other or the control. This shows that there is a difference in the rate of photosynthesis when exposed to increasing amounts of sodium bicarbonate. This leads us to reject the null hypothesis and provides support for the alternative hypothesis. The variation of the concentration of sodium bicarbonate will have an effect on the rate of photosynthesis of spinach (Spinacia oleracea).
Introduction Photosynthesis is the process whereby chlorophyll containing cells in green plants convert incident light to chemical energy and synthesise organic compounds from inorganic compounds (Great Illustrated Dictionary, 1984). It could also be presented by this equation (6CO2 + 6H2O C6H12O6 + 6O2), all in the presence of sunlight (Mader, 2010). The word photosynthesis means “putting together with light” (Ashley, 2000). In order for plants to photosynthesis, a source of light energy is needed. This energy is normally obtained from the sun.
The large dead plants block other alive plants from the sunlight. As plants’ main source of nutrients is made from photosynthesis from sunlight, the blocked plants can not grow either (The Fuse School; 2013). As a result, the aquatic plants have a harder time surviving in the water. The environmental impact does not end there. Aerobic bacteria eats the dead plants and uses the nutrients to grow and multiply faster.
There are three qualities of light that are mostly influence in vitro growth of the plant tissue culture; which are wavelength, photoperiod as well as light intensity. As for the wavelength, plants absorb blue and red lights which give the biggest effect on the growth of plants. The plant growth rooms usually are equipped with the cool white fluorescent tubes. Different types of explant give different responses towards the effect of light towards plant. Photoperiod is the length of time the plants receive amount of light within 24 hours.
Aim: How does light intensity affect the rate of photosynthesis in Elodea (pondweed)? Introduction: In this experiment, we were testing the rate of photosynthesis in elodea. For a plant to photosynthesize, it needs carbon dioxide and water and sunlight, a factor of photosynthesis. In order for us to measure the rate of photosynthesis, we needed to measure the products that were made, glucose and oxygen. As oxygen was a visible product, we counted the oxygen bubbles made when we moved the source of light.
In fact, many food manufacturers already use nanotechnology in food.The most compelling aspect of nanotechnology in regard to agriculture is the ability for artificial photosynthesis to be utilized in regard to solar power. Scientists have used a device called a water splitter which allows hydrogen to be produced to create power when the sun is not directly shining. On the down side, this device relies on silicon, which corrodes quickly when put in contact with electrolytes, and has only been able to be used in short durations. Nanotechnology is also being used to develop long-term environmental clean up functions, in order to remove pollutants from air and water. This is being done by creating
It 's true! Without water all life would die. In addition to being an important part of cells, water is also used by plants to carry and distribute the nutrients they need to survive. Water is vital to the survival of everything on the planet. The Earth might seem like it has abundant water, but in fact less than 1 percent is available for human use.
They harness their energy form the sun to carry out photosynthesis (Miller and Levine) However, other things are needed to do photosynthesis as well. Carbon dioxide and water are the key components to process photosynthesis. Chloroplast makes photosynthesis happen. They are organelle, or a specialized structure that performs important task in the plant cell. Cell in the plants co-operate to help
