The Effects of Sucrose Molarity on Cells in the Stem Tuber of a Potato Planning In this investigation I am trying to find out what molarity of sucrose solution is same as the molarity of sucrose in the cells of a potato. In this experiment I am going to change the molarity of the sucrose solution out the cells of potato. I predict that if the molarity of sucrose solution outside the cells is isotonic to the molarity of the sucrose inside the cells then there will be no change in weight
Determining the Water Potential of Potato Tuber Cells I will carry out an investigation that will enable me to determine the water potential of the tested potato tuber cells. Water Potential is the measurement of the tendency of water molecules to move from one place to another. (Ridge 1991) Water always moves down the water potential gradient, therefore moving from an area of higher water potential to an area of lower water potential. Equilibrium is reached when the water potential
A Comparison of the Water Potential of Potato and Sweet Potato Tubers Aim The aim of this experiment is to compare the water potential of two different plant tissues, potato and sweet potato tubers, by measuring the gain or loss of water when samples of the tissue are placed in a range of concentrations of sucrose solutions. Background information Osmosis is the movement of water molecules from a region of their higher concentration to a region of their lower concentration through
Determining the Water Potential of Potato Tubers using Gravimetric and Chardakov Techniques 1. INTRODUCTION: Water potential (W) is the measure of free-energy status of water in plant cell, which is the driving force governing the movement of water into and out of the plat cell and affect various metabolic activities (O’Leary, 1970). Water potential is depends on different solute concentrations, pressure and matrix a particle; measured in Mega Pascal’s (MPa) and written as: W = s + p
Water Potential of Potato Tuber Cells AIM: To find the water potential of potato tuber cells. HYPOTHESIS: When cells are put in a solution with a different water potential than inside of them, cells will gain or loose water. If concentration of solution is the same, there will be no change in mass. THEORETICAL BACKGROUND: If a sample of tissues immersed in solution of varying water potential (concentration of water molecules), the cells will loose or gain water by osmosis
Investigating the Concentration of Plant Cell Sap Using Potato Tuber Cells An experiment to work out the concentration of plant cell sap using potato tuber cells First of all and the most important are the safety precautions we will take throughout this experiment · Wear safety glasses to protect eyes · Handling the acids carefully · Careful while using kitchen knife (And all the simple things such as not running etc.) Another important aspect before we start is making the
DETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried, weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated. Apparatus.  Specimen tubes with stoppers x6  1cm3 diameter cork borer  razor blade  filter
linked is best described as a rhizome. The first step in comparing hypertext to a rhizome system is to understand just what a rhizome is. The philosopher Gilles Deleuze came up with the idea and Janet Murray applied to hypertext. A rhizome is a tuber root system in which any point may be connected to another point. “Deleuze used the rhizome root system as a model of connectivity in systems of ideas” (Murray 132). One simplified example of this is the prewriting technique of making a web. There
previous state. The tissue that has been in the hypertonic (0.5M sucrose) should be far more placid than it was before. This is because of osmosis - water diffusing in and out of the potato tissue cells. Apparatus ========= · 1 potato tuber · 1 cork borer · 1 ceramic tile · 1 scalpel · Paper towels · 6 boiling tubes · 1 marker pen · 0.1M, 0.3M, and 0.5M sucrose solution · Access to an electric balance · 1 funnel Method ====== The volume of each boiling
Table 1 shows the mass of young, old and freeze-damaged potato tubers before and after being incubated in sucrose solutions of different concentrations for 45 minutes. For young potato tubers, the mass increased after being incubated in solutions with concentrations of 0.15M, 0.20M and 0.25M, while the mass decreased after being incubated in solutions with concentrations of 0.30M, 0.35M and 0.50M. For old potato tubers, the mass increased after being incubated in solutions with concentrations of
Experiment to Investigate Osmosis in Potatoes The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements: a) It is the passage of water through a semi permeable
stored products such as dried materials of animal and vegetable origin, nuts, herbs, spices, grains and grain products etc. They usually feed heavily at the larval stage (Cabrera, 2007). The insects are also found to develop favourably on root and tuber crops such as cassava, yam, cocoyam and sweet potato mostly in the dried or processed state for storage (Adebayor, 2002). The insect usually infest and contaminates stored products with their cocoons and body parts when they die, thereby reducing the
qualities of tropical root and tubers. In addition to starch and sugar, root crops also contain some non-starch polysaccharides; including celluloses, pectins and hemicelluloses, as well as other associated structural proteins and lignins, which are collectively referred as dietary fibre. The protein content and quality of tropical roots and tubers (Table 1.6) is
Composite flour is a mixture of flours from cereals and root tubers. Flour from ground legumes such as soya bean may also be added to increase the protein content of the composite flour. Wheat is often the cereal incorporated in the mixture but cereals such as maize, rice, buckwheat and millet can also be utilized (Popper, 2006). Root crops are the edible energy–rich underground plant structures developed from modified roots. While tuber crops are those crops in which the edible carbohydrate – rich
and in length. I believe this because each Molarity of sucrose will change the potato's water content. This will happen because either the concentration will higher in the sucrose and lower in the Tubas or lower in the sucrose and higher in the Tubers. Therefore water will travel in or out of the potatoes cell though its partial permeable membrane. Preliminary Method · I will firstly get 10 test tubes and to test tube racks · Then I will cut 9 pieces of potato · I will then get
What are aroids? What is taro? Aroid, or taro, is the common name for the highly divers members of the Araceae family of plants which consists of over 100 genera and around 3750 species. Several of its family members, such as Anthurium, Caladium, Dieffenbachia and Philodendron, are among the world’s most popular ornamental plants. Plants of the Araceae family belong or are related to the arum family, and although widely known as aroids, if aroids are referred to as food, these are commonly referred
paleo diet allows foods found in a natural hunter-gatherer diet: grass-fed meats, fowl, fish, fruits, nuts, eggs, vegetables, oils and tubers. Of course, this doesn’t mean you should deep fry everything or down a three-pound tub of mixed nuts. Focus on healthy meats and proteins to keep yourself satisfied between meals. Remember to limit the high-carb fruits and tubers if your goal is weight loss. If the cavemen could do it, so can we! What Didn’t the Cavemen
One of the most interesting indigenous groups in the world is the Batek of Malaysia, this is a group of people that live in the oldest rain forest of peninsular Malaysia. Orang ASli means “Original people” in the native Malay Language, and they truly are the original people of the land. Being a nomadic group of hunters and gatherers, means that they are at the mercy of the land and the elements for survival. Batek beliefs note that, the rainforest was created by “superhuman” beings for the Batek
The Tuber that Unites a Hungry World Potatoes are a truly globalized crop. They can be found all around the world from the Americas to China, from Africa to Europe. In each of these places, they play their own unique role but the secret to their success is their hardy nature and their nutritional value. They become valuable to some peoples because they are able to grow in geographical locations or in weather situations that would cause other crops to fail. They are also incredibly nutritious, providing
staple crops. A staple crop is a food that makes up the dominant part of a populations diet. These crops included Potatoes, Oca, which is a highly productive perennial plant with waxy, brightly colored tubers, Ulluco (oo-yoo-ko) a primarily grown vegetable, but also used as a leaf vegetable; the tuber is the primary part; they are like potatoes, waxy outside but various colors like red, orange, and yellow and the leaf is used and is similar to spinach, Quinoa (keen-wah), which is a protein packed grain
