Transpiration Lab Write-up. Introduction Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference‚ water vapor diffuses from the spaces of the leaf‚ through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less

Introduction Diffusion and osmosis are two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

How to Write a Lab Report Lab reports are formal papers that describe and analyze lab experiments. They follow a very specific format. If you study this paper carefully and follow its directions‚ you will find that these papers are not at all difficult and can have a positive impact on your Biology grade. Paper formatting: The paper should be typed and double spaced. Use a standard 12 point font (do not use cute fonts or colored paper!). Except for the title and abstract – each section

Bacteria Lab Write-Up Jianna Liu P8 Purpose: The purpose of this lab is to find out which substance‚ alcohol‚ antibacterial soap‚ water‚ or hydrogen peroxide‚ is the best at preventing the growth of bacteria. Hypothesis: Antibacterial soap will be the best because soap is a substance that people use to wash their hands because it takes away the germs. Even the name‚ antibacterial soap‚ suggests that it fights off bacteria. Hydrogen peroxide is second because it is used

The Mollusks Tori Johnson Kylie Pocrnich December 17‚ 2012 Zoology In this lab‚ my partner Kylie and I will be examining the internal and external features of the clam. “Like all mollusks‚ a clam has a mantle which surrounds its soft body. It also has a muscular foot which enables the clam to burrow itself in mud or sand” (Miller and Levine). Clams are mollusks with two valves also nickname the bivalves. Clams are mostly marine animals however; the clams we will dissect are freshwater clams. Adult

Pouri‚ Nikole Period 1 1/14/12 Mitosis Lab Write-Up Purpose: The purpose of this lab is to understand the phases of mitosis through a hands on experience and not just textbook information. The objective is to visually determine each phase through a microscope with a clear understanding of what is happening. With this knowledge and this visual a picture is to be drawn as descriptive as possible for each phase. Materials: The materials needed are; 1) Microscope 2) A slide containing plant

Acids & Bases Lab Write Up Lab 2 Introduction There are many acids and bases all around us. An acid is known as a hydrogen ion donor (H¯)‚ and a base is known as a hydrogen ion acceptor (H⁺). Acids and bases are represented by the pH scale. The pH scale shows the strength that an acid or base has. This scale ranges from 0-14‚ with 0-6 being acids‚ 8-14 being bases‚ and 7 being neutral‚ such as water. This is defined as the negative log of an ion atom (pH=

Osmosis Design Lab November 19‚ 2011 Biology Defining the Problem and Selecting the Variables Research Question: What will happen to mass of the cell when it is placed in different solutions while trying to reach equilibrium? Background Information Osmosis is the procedure where water or different types of liquids move through a semipermeable membrane. This type of passage is considered as simple diffusion where no energy is required. This means that the liquid will have
