How Does Wavelength Affect The Growth Of Plants

429 Words2 Pages

The experiment was conducted to understand the effect of different wavelengths on the growth of plants through the use of investigative processes. By making filters out of cellophane to try and limit the light the plants are exposed to so it is easy to compare the growth between wavelengths completed this experiment. It is intended that the experiment will replicate the background research to clearly show that certain wavelengths allow the plants to grow faster or causes it to die and hence showing which colour the chlorophyll uses more of. It was hypothesised that the plants only exposed to the blue or yellow light will grow the most. The plants used in this experiment will be basil (Ocimum basilicum) , an easy plant to grow and maintain. Basil grows best in direct sunlight and It is recommended that the basil plant is watered at least once a week. To thrive and grow basil like all plants need …show more content…

The colour seen is a result of the light reflected into our eyes. The three primary colours are blue, red ad green these all can be mixed in different quantities to produce all the colours on the colour spectrum. The light wavelengths can be identified by its frequency also known as how fast the wavelength vibrates. http://sciencelearn.org.nz/Contexts/Light-and-Sight/Science-Ideas-and-Concepts/Colours-of-light The process of photosynthesis uses the energy from sunlight to convert glucose from CO2 and H2O. Photosynthesis mainly occurs in the leaf, which has adaptions such as its thinness to allow gasses to diffuse quicker, and they also have a large surface area to maximise light absorption. Another reason why it occurs in the leaf is because it has all the necessary structures to perform photosynthesis efficiently.

The basic set-up for this experimental design consists of two sets of 6 plants (since two groups were combined in order to gather more data). Each set consists of 3 plants that were grown in long-day conditions and the 3 plants in short-day conditions. After the data from Week 1 (used as the comparison/control in this experiment) was collected, the long-day plants were put under lights that would create an extreme long-day condition, while the short-day plants were put under lights that would create an extreme short-day condition. After a week under these conditions, these plants would be removed from these conditions and an analysis of the closing and reopening times for the plants would be conducted in the same fashion the Week 1 Data was collected. In this experiment, in each set of plants, two of the extreme long-day plants and two of the extreme short-day plants would receive the light stimulus (0.3 g), while the last two plants would receive the heavy stimulus (1.0 g).

The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.

Compare And Contrast Cellular Respiration And Photosynthesis

420 Words | 2 Pages

photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

Another way is to make sure that the carbon dioxide concentration is also at a consistent temperature. It is suggested that the range temperature is 5˚C to 45˚C. So the experiment should use Co2 concentration at the temperature of

Concluding Plant Growth The hypothesis for this experiment was accepted. The hypothesis was; If the plant seeds were exposed to microwave radiation, then the growing process will increase. Three plants were planted, two of the three seeds, were microwaved for different times to see if microwave radiation helped the plant grow faster. The question that was asked was, does radiation affect the way plants grow?

Nitrogen Experiment Report Nitrogen is an important factor of plant development. Our experiment tested what happened when the level of nitrogen the plant had was changed. We started with the following question: How would the amount of Nitrogen available to a plant change how it grows? This was tested by three jalapeños plants; one with correct levels, one with extra nitrogen, and one with less nitrogen.

When punching out the leaf disks, the big veins were to be avoided, so that the leaf disks would have the same uniformity of cells. Cells that are in the veins have different purposes than the rest of the cells in the plant causing a slight difference in the anatomy. With some of the plants, it was hard to avoid the veins as they took up much of the plant. Another error to the lab is that fact that different factors affect photosynthesis. When testing the plants, it is unknown what factors are causing the plants to go through photosynthesis.

Chlorophyll, a green pigment, is the main pigment that absorbs light to produce food for a plant. There are two types of chlorophyll: chlorophyll a and b.(Friedl) Anthocyanins are red leaf pigments that are contained in only some trees. The anthocyanins purpose is to pull all the sugar and nutrients possible from the leaves before the leaves fall for the winter season.(Horton2) Xanthophylls are yellow pigments contained in the leaves. Xanthophylls function as accessory pigments that capture wavelengths of sunlight that are not absorbed by chlorophylls.

How Does Colored Light Affect Plants

499 Words | 2 Pages

When testing the effects of colored light on plants, it is important to know the processes that would directly affected by light. It is also important to know more about light spectrum itself and where the colors place on the spectrum. Of course, the process most affected by the color of light would be Photosynthesis. In Photosynthesis, light is one of the main “ingredients” that combine to form the sugars and carbohydrates that plants use as energy and the oxygen that plants pump into the environment. Different lights affect plant and plant growth, for instance, plants reflect most green light.

Effect Of Light Intensity On Photosynthesis

1022 Words | 5 Pages

Chloroplasts are organelles that carry on photosynthesis; carbon dioxide diffuses into the chloroplasts in the leaves (Mader, S. 2010). Sugar and oxygen are released during the process. In order to photosynthesize, plants depend on light energy from the sun. The rate of photosynthesis will increase or decrease depending on the colour of light being absorbed, blue light results in the most photosynthesis occur and green light results in no photosynthesis occurring.
