Absorption spectrum is related to my experiment which shows that green color is the poorly absorbed and red and blue color would be absorbed well. Moreover, plants are necessary for us since we inhale oxygen which is produced by plants. It means that producing oxygen by using the process of photosynthesis is important for our body and environment. Therefore, I am willing to see how the use of different colors of lights effect the rate of
Aerobic cellular respiration and oxygenic photosynthesis are the main pathways of energy flowing in living things. Photosynthesis is known as a process that is used by plants, algae and bacteria get energy from sunlight into chemical energy. Aerobic cellular respiration makes ATP, finalizes e- acceptor is oxygen. Aerobic cellular respiration involves the products of photosynthesis, which are glucose and oxygen, while photosynthesis uses the products in aerobic cellular, which are carbon dioxide and water. These reactions are how cells make and store energy.
2018, Accessed 16 March 2018) There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis. (From Light Energy to Chemical Energy, Accessed 08 March 2018). Products to are made through photosynthesis as glucose is transported in to the plant as soluble sugars and stored as starch which is insoluble hence it is unable to escape from the cell. Although starch is able to revert back into glucose in order to release energy by respiration both useful for fats and oils for storage through the plant, proteins for growth and repair and cellulose for their cell walls. Figure 2: Structure of a leaf (FTEXPLORING, 2014), Accessed 16 March 2018) Chlorophyll is an essential need to photosynthesis as it is able to trap both blue and red light.
The hormone cytokinin causes this after the exposure of light. Chloroplasts contain chlorophyll and due to this the plant turns green. 1.1 Research question For this experiment, I want to find out what will happen to cress seeds that are etiolising (growing in the dark) when they are then exposed to light. To conduct this experiment, I came up with the following research question: ‘Will exposure to light after a set period of etiolation cause a plant to de-etiolize?’ 2. Hypothesis If a plant is exposed to light after a set period of etiolation, then a plant will de-etioize and the production of chloroplasts instead of etioplasts will be stimulated.
CHAPTER II RELATED LITERATURE AND STUDIES This chapter presents the review of related literature and studies. Review of Related Literature Photosynthesis is the transformation of sun energy into chemical energy, which plant can actually use. Only plants, or autotrophs, can do this. Autotrophs are simply organisms that can produce their own food. They harness their energy form the sun to carry out photosynthesis (Miller and Levine) However, other things are needed to do photosynthesis as well.
In plants, the presence of chlorophyll pigment is vital for photosynthesis. However, plant cells produced flavonoid as a response to stress conditions as protection mechanism. In addition, light energy is converted into chemical energy in plant and fungal cells using quinones pigments. On the other
If there is less water to combine with the carbon dioxide for photosynthesis, then less sugar and oxygen is made. Radish seeds can grow all year. Different amounts of water can affect the growth of a radish seed. The amount of water the seeds get affect the quality of the plant. The radish seeds like lots of water and moist soil.
The effect of the solar collector area was done in order to determine the optimum area for a solar still. The analysis showed that even though the production of the water increases with the increase of the still area but the efficiency decreases. Moreover if the brine depth is less in case of a still with higher area then the boiling of water takes place which in turn reduces efficiency. Hence, in our project we chose an optimum area and a brine depth that can prevent the boiling of
It is possible that these were the pigments needed to photosynthesize that plant or it was just an anomaly but it wouldn’t be known until further experiments are conducted. Under green light only Xanthophyll B was produced. It is possible that xanthophyll B is only needed under green light for this particular plant. Under red light both chlorophyll and xanthophyll were produced. Chlorophyll is produced under both blue and red light not because they produced insignificant pigments but because chlorophyll is very common and is necessary for a lot of
