Aim: To investigate the effects of different light intensities on photosynthesis in plants BACKGROUND INFORMATION: Aquatic plants can be used to demonstrate oxygen evolution in the process of photosynthesis. In theory, when an aquatic plant is placed in a solution containing a source of carbon dioxide (CO2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. These bubbles can be counted and the rate of bubbling can serve
INTRODUCTION Photosynthesis is a chemical process in which plants, algae and certain bacteria produce oxygen and glucose using the energy from the sunlight. This process is important for life because of the oxygen and glucose released; these products are used in many life processes. Photosynthesis takes places in a wide variety of organisms and also comes in different forms; these include a form of photosynthesis that does not produce oxygen which is called anoxygenic and the other form which does
plant microbiology Plant pathology is the study of plant diseases caused by pathogens and environmental conditions. Food loses due to infection caused by microorganisms like bacteria, fungi, viruses, protozoa etc has become one of the unrelenting effects. Basic culture methods Plate Procedure In this process, the number of microbes present in a mixed sample are calculated and then add this sample on an agar medium and allow it to solidify. Dilute the samples and pour it on agar plate and incubate
technology. Solar energy has been used from the beginning of time as an important part of photosynthesis for plants.
In recent years, with rapid growth of global population hitting 7 billion in 2011, and expected to rise to 9 billion in the year 2050. With this, comes the increase in demand for food and water resources. The growing population leads to increased agricultural activities to feed the demands of the population. There has since been a controversy on the severity of the increase in agricultural activities, creating concern on freshwater pollution because these activities are inevitable. On one hand, this
of leaves, shortening of internodes, stunted growth are common symptoms of mosaic disease as shown in Figure 1.2(a). 1.3 Leaf structure Leaves are adapted to execute their function and have a large surface area to absorb sunlight. Leaves enable photosynthesis to occur. Plants have different types of transport tissue, phloem and xylem, that move substances in and around the plant. Water evaporates from the leaves,
