Miss Yuhas Can a Potato Produce Electricity? The purpose of this experiment is to see if a potato can produce enough electricity to light a light bulb. Electricity is a kind of energy that can move from one place to another or stay in one place. The energy that can move from one place to another is called an electrical current. This experiment will try to create an electrical current by using a potato as part of a circuit. A circuit is a circling path that the electricity will follow. A circuit can be created when electrical materials are attached to wire, but if there is a break in
Potato virus X (PVX) is a plant RNA virus. Its infection cycle includes invasion of the host plant, RNA replication, translation of viral proteins, cell-to-cell movement and release of new virions. Upon infection, PVX releases its plus-strand RNA genome from the virion and produces a viral replicase using host translation machinery. The replicase synthesizes minus-strand RNA. Subsequently new plus-strand genomic RNA (gRNA) and subgenomic RNAs (sgRNAs) are produced. Movement and coat proteins are translated from the sgRNAs for encapsidation and movement through plasmodesmata. In this mini-review, all aspects of the virus infection cycle of PVX are discussed.
So the experiment will be based upon the movement of water. The first potato chip will be placed in a zero percent solution. I believe that this will increase the mass. I believe this because the zero percent solution has a lower concentration than the cell sap inside the potato. The potato takes on the water through osmosis and the cell pushes out from inside the cell making it swell and become more rigid.
The Effect of Placing Pieces of Potato in a Sucrose Solution [IMAGE]Osmosis Osmosis What is osmosis? If two solutions of different concentration are separated by a semi-permeable membrane which is permeable to the smaller solvent molecules but not to the larger solute molecules, then the solvent will tend to diffuse across the membrane from the less concentrated to the more concentrated solution. This process is called osmosis. Osmosis is of great importance in biological processes where the solvent is water.
Finding the Water Potential of Potato Cells Aim: Our aim was to discover the water potential of potatoes cells using different concentrations of sucrose solution Science: Osmosis is 'the movement of water molecules from a region of higher water potential to a region of lower water potential through a semi-permeable membrane' www.s-cool.co.uk 'Water can move between cells (unligninified) freely as the cell walls are permeable. However its movement is controlled by a number of factors, which are given names; solute potential ([IMAGE]), Pressure potential (+ Matrix potential =0 normally)([IMAGE]) and water potential ([IMAGE]). Solute potential ([IMAGE]): this refers to the amount of substance dissolved in the cytoplasm. This effects water movement because water always moves from a less concentrated medium to a more concentrated medium.

When scientists first began, they thought that positive energy flowed first. Today, it is a common theory that electricity works best using the conventional current because it flows positive to negative. You said in class that electricity flows through circuits and works like water. The...
Potato cores are made of countless cells. A semi-permeable layer called the cell membrane surrounds each potato cell. The cell membrane acts as a barrier between the cytoplasm and its environment. It also gives the cell its structure. The reason why the cell membrane is semi-permeable is because it is mainly composed of a phospholipid bilayer that only allows non-polar and small molecules to pass through it. Fortunately, the cell membrane also contains many transport proteins that allow charged and larger molecules such as water to move into the cell. Other proteins in the cell membrane include glycoprotein and enzymes which are involved in cellular functions such as recognition of other cells and chemical messaging. Another component of the cell
Before we can properly analyse a circuit, we must first understand what a circuit is. A circuit is a closed loop that allows charges to move continuously. There are two requirements that must be met in order to create a circuit: it must be a closed loop with conductive wires connecting to both the positive terminal and negative terminal of the cell, and there must be a source of energy that can increase the electrical potential energy of the charge.
In a closed circuit the electric current flowing within the battery is due to the chemical reactions, we can say that electric current flowing will take place only if the voltage across the battery voltage(V) is different from the chemical potential (E).[2]
The circuit is not completed, therefore the charges can't move off the end of the wire and continue to go. Voltage, Current, and Resistance. When working with circuits, the three basic elements to analyze the circuit are voltage, current, and resistance. These three readings help you find out all the information you need on how the circuit will work and they are all related to each other through Ohm's law which states that voltage is equal to current times resistance.
Edison searched for the proper "filament" or wire, that would give good light when electricity flowed through it. He sent people to the jungles of the Amazon and forests of Japan in his search for a perfect filament material. He tested over 6,000 vegetable growths (baywood, boxwood, hickory, cedar, flax, bamboo) as filament material.
Thomas Alva Edison is a very well-known American inventor. He invented about 1093 devices that influenced us greatly, such as light bulb, microphone, telephone receiver, universal stock ticker, phonograph, kinetoscope (used to view moving pictures), storage battery, electric pen, and mimeograph. Edison also improved many other existing devices as well. In the period from 1878 to 1880, Thomas Edison began serious research into developing a practical incandescent lamp. Edison and his associates worked on at least three thousand different theories to develop an efficient incandescent lamp. In 1878, Edison built his first high resistance incandescent electric light. Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing arc lamps, which were too bright to be used for small spaces such as the rooms of a house.Edison's lamp would consist of a filament ho...
