As I’m sitting there‚ watching a hot potato – a literal hot potato‚ fly towards me‚ I’m wondering what I got myself into. Rewind a couple of days and I’m in school talking to the new girl named Jocelyn. She wore converse and had these cool long side bangs that everyone in the eighth grade was jealous of and had come from some far off place called Falls City. As the new kid with the cool hair‚ everyone was competing to lure her into their posses’. I‚ a typically quiet‚ reserved person‚ tended to stick

Measuring the Water Status of Potato Tubers Objectives: Upon completion of this laboratory you should be able to: 1. determine the water potential of a plant tissue by the Chardokov and gravimetric techniques and understand the underlying theory. 2. determine the osmotic potential of a plant extract by the freezing point depression method and understand the underlying theory. 3. describe techniques for measuring the pressure potential of a plant tissue. 4. describe techniques for measuring

Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially

is submersed in a high concentration of saline solution it will create a hypertonic environment and therefore cause the cell to rupture due to the process of osmosis. The methods used to collect data were observation and note taking. Overall the results proved the hypothesis correct with major findings being a higher concentration of salt causing a hypotonic environment and a low concentration. Recommendations included major changes to the materials and method which would allow quantities data to

Every winter road salt is used on sidewalks‚ roads‚ and highways to melt snow and ice. These are to prevent human activates from turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a

even though the poet and his mother are having a good time peeling potatoes‚ his mother is ill and they are brought to their senses that the happy times will soon be brought to an end. 2. The potato is an important symbol in Ireland because of its value as a food staple and reminder of the terrible potato famine in the 19th century. What personal symbolic value does it have in this poem? In this poem the potatoe is a symbol of time shared with the poets mother‚ time when it is just him and his

Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane‚ while osmosis is the process in which water molecules move passively from a region of higher water potential to a region of lower water potential through a differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium

may imprint on a child’s mind as what is normal. The child may start to believe that is all they are capable of and all attempts to the contrary are meaningless. A mindset established from a depressive mindset. The multiple generations displayed in Potato Eaters amplified this depressing‚ cathartic thought into the inescapable vile it takes its victims as. In a type of antithesis to the parents who works hard at something they love‚ the attitude helps make a difference between the children emerging
