    Transpiration Lab Write Up Purpose/Question: How do environmental factors affect the transpiration process in plants? Research: Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. Transpiration...

  • Transpiration Lab Write Up

    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...

     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...
