Better overall health Organically grown foods have more nutrients—vitamins, minerals, and micronutrients because the soil is managed and nourished with natural techniques such as green manure and crop rotation which are absolutely safe and healthy. Healthy food means better nourishment as well as better and healthy living. 2. Antioxidant content Antioxidants have a positive effect on the overall health and organic food help in contributing beneficial antioxidants to the body. The organic foods are free of such chemicals which react with vitamins or minerals thus lowering the impacts antioxidants in the food products.
1 Rhizosphere Interactions Jacob Griganavicius Robyn Dumalo Introduction Plants are the most important living organism on our planet today, without them; humans would most likely not be present on this planet. Plants are photoautotroph, which means they get energy from sunlight in order to change carbon dioxide (CO2) and water (H2O) into organic materials for all living organisms1 . The reason that plants are so important to humans is that they go through a main process to produce oxygen so humans can breathe and it is called photosynthesis. Photosynthesis is the process that converts light energy to chemical energy that is kept in sugars and any other organic compounds1 . Photosynthesis can occur anywhere there is green on the plant
Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently. Hypothesis: If four lights (UV Light, LED Light, Infrared Light, and Blue Light) are used to perform photosynthesis on a spinach leaf, then the spinach will respond most to the blue light and perform a more efficient photosynthetic process.
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
Growth and development of C3 and C4 plants at different light levels. Light plays a major role in plant growth and development, because it is also a major component for photosynthesis, which is an essential process for plants to manufacture carbohydrates/sugars as their food source. Very low and exteme light conditions can negatively affect the plant growth, therefore certain amount of light is needed to be absorbed by the leaves. Result show that in the presence of high light and treatment shoot, root and leaves had the highest increase in biomass, while in in presence of low and no treatment the leaves, shoot and root had the lowest biomass. This lead to a conclusion that says light is a significant variable for the plant growth and development.
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.
1. Introduction Etiolation is a process which occurs in plants which are grown without light. This process increases the chance of a plant to reach the light and to actually photosynthesise. Certain characteristics occur with plants grown in the dark, these are: • Long, weak stems - Due to etiolation a plant can increase the possibility that it will reach a light source, often it will have to go higher. Therefore the stems are often longer.
It is the most abundant pigment for photosynthesis as it absorbs light from most of the spectrum and transfers the energy to the reaction center. Carotenoid contains carotene which allows it to resist dissolving in water. It is considered an accessory pigment as it absorbs light that chlorophyll could not. It is also responsible for protecting chlorophyll from absorbing excess light which could cause cellular damage.
Introduction Green roof are defined as roofs that support vegetation, covering either full or partial of live plant material. At present, cities are now considering extensive planting as a mean of improving of air quality. Green roof can also be a good material tool in the environment. Most of the time, people would be confused to identify the green roof with rooftop garden, although the benefit of green roof and rooftop garden are quite similar but there are significantly differences between the two. Green roof is always put up with layered system unlike rooftop garden that has characterized by built-in planting areas for food production and can occupy a small proportion of roofs, but in other places, they made green roof as there garden.
GREEN COMPUTING: NEED AND IMPLEMENTATION R.Suganthi (Department of IT) Sri akilandeswari women’s college, vandavasi ABSTRACT Green computing is an effective method of protecting our environment from the hazards material and its effects from computer and its related objects like printer, monitor, storage devices, and networking and communication systems. Its goal is to shrink risky these equipment and to maximize the effectiveness of the product lifetime. Efforts have to be taken from recyclability and bio-grad ability of waste goods. This can be done through this green computing .The usage of computers in all fields is growing nowadays .the carbon contents released by these goods are also growing day by day, it affects our atmosphere growingly
