solution water will move from the cell into the solution until the cell shrinks(1). Further water loss causes can cause the cells protoplasm to peel away from the cell wall leaving a gap between the cell wall and the cell membrane‚ a process called plasmolysis(1) However if the cell is placed in a hypotonic solution‚ water will move from the solution into the cell and cause the cell to burst (1). A cell in an isotonic solution neither swells nor shrinks because there is no concentration gradient for

Simple diffusion The term simple diffusion refers to a process whereby a substance passes through a membrane without the aid of an intermediary such as a integral membrane protein. The force that drives the substance from one side of the membrane to the other is the force of diffusion. In order for substances to pass through a cell membrane by simple diffusion it must penetrate the hydrophobic core of the phospholipid bilayer. The types of molecules that can do this are themselves substantially

Someone screams. Jay turns‚ following his wife’s eyes behind him to the front door across the diner. Three men in wet ski masks and camo hunting gear stand holding guns‚ their barrels dripping rain. “Phones‚ wallets‚ whatever‚” the man in the orange mask says. “Put all that shit on the table.” Turning back to his wife‚ Jay raises his hands‚ fingers spread just above the table‚ and looks in his wife’s eyes. “Syl‚” he says‚ his voice a pointed whisper. “Syl.” Her eyes float slowly from the gunmen

chemicals and HCL combine‚ changing the water’s pH levels. When pH levels are too high‚ the water is labeled as being too acidic meaning it is too hazardous to drink or touch. AST International claims that “Most of us automatically classify lemons‚ rhubarbs and vinegar as acidic solely because of the way they taste. We don’t realize that strawberries and tomatoes and plenty of other foods are acids too” (Tanasescu). The release of hydrogen ions is how we determine if foods are classified as acids or

Amusing facts about Sweden‚ Swedish Culture‚ and Swedish Governance‚ compiled by an American. As of 2004 you can pay your Swedish taxes by sending an SMS message from your cell phone. The government sends you a completely filled out tax form and if it looks good you just go online and click okay to pay your taxes. Taxes are generally between 50 and 70% of your income. (Of course your employer already pays the full amount of your salary to the government in taxes before you even get anything.) Companies

DIFFUSION= The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. OSMOSIS= Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane.

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

concentrated solution of water‚ water then passes through the cell wall‚ the cell membrane‚ and the cytoplasm and into the vacuole. The increased pressure of water inside the vacuole is called Turgor pressure. Then the cell becomes turgid. Plasmolysis is the opposite of turgor. This happens when plant cells may be placed in a less concentrated solution of water‚ although this is very unlikely to happen in nature. Water passes out of the vacuole‚ the cytoplasm‚ the cell membrane and the cell wall
