9.2.6 Explain how water moves from the soil to the leaves of a plant. At first water enters the root by osmosis because the soil water has a lower solute concentration of minerals than the epidermal cell cytoplasm (there is a water potential gradient). Water movement across the cortex cell is by two pathways both involving a water potential gradient. The cortex cell cytoplasm has a solute concentration gradient. This moves water symplastically from cell to cell by osmosis. The Apoplastic

Name: Hesham Marzouk “Journal Response Question” The man was less interested when she explains that they were “never” hit‚ because when she explains to him about what her father did when he was digging his elbows into the wooden table‚ the man thought it wasn’t that bad. He wouldn’t tell her about his response for that‚ but she already knew when she said “He smiled {the man}‚ relieved that we wouldn’t have to go there. He

Cell Respiration & Photosynthesis BIO STUDY GUIDE (Ch. 9.1-9.5‚ 10.1-10.3) I) CELLULAR RESPIRATION A) Catabolic Pathways A.1) Fermentation: partial degradation of sugar that occurs w/o oxygen A.2) Cellular Respiration: oxygen is used A.3) Redox Reactions (Oxidation-Reduction that exchanges electrons) Oxidation: loss of electrons (energy must be added) Reduction: addition of electrons. (-) charged electrons added to atom reduce amount of (+) charge of that atom A.4) Stepwise Energy Harvest

ISC Board Important Questions Biology [Set-1] Q1. a) (i). Absorption spectrum and Action spectrum Answer: A curve obtained by plotting the amount of absorption of different wavelengths of light by a particular pigment is called absorption spectrum of that pigment. An action spectrum is a curve showing the effectiveness of different wavelengths of light in stimulating the process being investigated. (ii). Heart Wood and Sap Wood Answer: In most trees the outer light colored region of the wood

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

Margaret Drabble said "Our desire to conform is greater than our respect for objective facts." This is a true statement because it perfectly describes our society in the fact that people would rather conform to what everyone is in belief of then to try and go against it and stand up for what you think is right. It’s easier to just step in line with what everyone is doing‚ instead of stepping out of that line and trying to fight it and go against it. There are many examples of this case that Drabble

Frederick Griffith | This person made an experiment that involved injecting mice with pneumonia: smooth S cells‚ rough R cells‚ heat-killed S cells‚ and heat-killed S cells with living R cells. | Avery‚ McCarty‚ and MacLeod | First to show that DNA was the genetic material‚ but not believed. Repeated Griffith’s experiment‚ but subjected the strains to different enzymes‚ isolating RNA‚ DNA‚ lipids‚ carbohydrates‚ and proteins. Only the DNA killed the mice; the others had the mice survive. | Hershey
