Processing removes the water which reduces the bulk and also increases their storage life. The method of processing‚ ranging from simple boiling to elaborate fermentation‚ drying and grinding to make flour may vary depending on the varieties of roots and tubers. The taro flour production from fresh tuber soon after harvest serves as an effective procedure against storage loss. Converting fresh edible tubers to flours will avoid losses and ensure supply of the products from tubers throughout the year

bless you! Cassien TWAGIRIMANA ABSTRACT The Irish potato is one of major food tuber crops grown in Rwanda. It plays a key role in food consumption‚ nutritional security and reduction of hunger. Potato plant like other tuber crops requires sufficient supply of several essential elements for proper growth and function. It is a gross feeder and exploiting greater volume of soil nutrients including nitrogen‚ phosphorous‚ potassium and water. Potato production has become very important in Rwanda in

This essay aims to assess and investigate the effect of various solution concentrations on the activity of osmosis in plant tissue. Background scientific theory: Plants exchange gases (CO2 and O2) in maintaining vital respiratory processes and in carrying out photosynthesis; they absorb certain minerals and sugars so to use as a source of energy and eradicate wastes in order to maintain specific requirements for survival. Large amounts of water are absorbed by root hairs and are then distributed

ANDERSON’S WATER POTENTIAL VIDEO (SAVES TIME AND EFFORT!) Water potential is the potential energy of water per unit area compared to pure water. Which allows you to figure out where water’s going to flow due to osmosis‚ gravity‚ pressure and even surface tension. It also allows you to figure out if water will flow in the first place and if it will flow into the cell or not. Water Potential (symbol psi) = Solute Potential (symbol psi s) + Pressure Potential (symbol psi p) Solute Potential= -i (ionization

mitigate the water crisis in developing country‚ and also the report takes China as an example. The first part of this report gives a brief introduction and background of the water consumption trend and the implication in this report. Secondly‚ three options are demonstrated in the following part‚ which are the South-to-North Water Diversion Project‚ monitoring system and individual behavior respectively. Then‚ the report evaluates these methods for both strengths and weakness effects in certain perspectives

reducing sugar) to form copper oxide‚ thus turning it from blue to a brick red/orange precipitate. The more red the precipitate is‚ the higher the concentration of reducing sugar in the solution tested. If more precipitate has formed‚ there are fewer copper ions remaining in the Benedict’s Reagent‚ therefore‚ the solution will appear less blue. This can be measured using a colorimeter‚ as it is known that the concentration of a substance is proportional to its absorbance of light. Fructose is the sugar

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose

is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules and surround them based on charges. In other words‚ water can dissolve ionic

FEASIBILITY OF TWO FRESH WATER SUPPLY TECHNIQUES IN SUDAN 1.0 INTRODUCTION Access to clean water is considered a basic human right and in many countries when sustainable development is considered‚ water is at the top of the list of priorities (Omer‚ 2008). The value of water is increasingly felt in areas such as Sudan‚ where precipitation is inadequate while temperatures are high resulting in dry or arid conditions (Food and Agriculture Organisation (FAO)‚ cited in USAID‚ 2010).
