Introduction Transpiration is a process which is similar to the evaporation. Water is lost at the surface of the plant such as leaves‚ stems‚ roots and flowers in the form of water vapor. It creates a pulling. Force which causes continuous upward movement of water and mineral salts and this force is called transpiration pull. Apart from to water‚ gas like carbon dioxides from the air can also pass through by the pore of the surface of the plants for photosynthesis. But in this experiment‚ we

Lab Report Practical 10 Transpiration Date: 05.02.2014 Tutorial group: F Name: Aimukambetov Sanatzhan Lab partner: Aibekova Lazzat Measuring rate of water uptake by plant Introduction Transpiration is the one of the important processes in the plant where the water movement through a plant takes place and after evaporates mostly from leaves (also from stems and from flowers). In other words‚ transpiration is one of the most important mechanisms in plants which affect and support the flow

Nicolette Lindberg 11/30/12 IB Biology 2‚ Period 1 Transpiration Lab Background Information- Transpiration is the loss of water from a plant. Plants transpire water out of the stomata in their leaves at a different rate in every environment. The amount of transpiration is affected by the environment‚ how developed the plant is to not lose as much water‚ the surface area of the leaves‚ and how affected the plant is by its environment (Von Bargen). For this experiment‚ the plant we used was (Viola

Prof. Marilyn Combalicer Exercise 3 TRANSPIRATION I. Result and Discussion 1. Effect of the Environment Factors on the Rate of Transpiration The quantitative rate of transpiration of the branch of papua dilaw was determined using the potometer. The distance travelled by the bubble in the capillary per unit of time was observed under different treatments: a. in front of a fan‚ b. exposed to light‚ c. fan and light‚ d. no treatment. Table 1. The transpiration rate of the branch of papua dilaw when

In this lab‚ I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than

Adriana Gutierrez AP Biology Lab 9 Analysis 1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration‚ so our independent variables would be bright light‚ fan‚ dark‚ and misted. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants

DESIGN LAB Factors Affecting the Solubility of a Solid in a Liquid In this experiment‚ my goal is to determine the affect of temperature in the solubility of a solid in a liquid. Research Question: How does the change in the temperature affects the solubility of a solid in a liquid? Independent variables: Temperature of the Solution Dependent variables: The solubility of the solid substance Controlled Variables: * The pressure of the room. * The mass of zinc chloride

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By

Transpiration is the evaporation of water from the aerial parts of plants‚ especially leaves but also stems‚ flowers and roots. Leaf surfaces are dotted with openings called stomates that are bordered by guard cells. Collectively‚ the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis.
