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 tricolor subsp.

2 + 6H 2 O Introduction: In this simulation‚ you will be looking at the production of carbon dioxide as a plant photosynthesizes. Oxygen is measured in the number of bubbles produced by the plant. Three factors that influence the rate of photosynthesis can be adjusted in the simulator to determine how each of the factors affects the rate of photosynthesis. Virtual Lab PreLab Questions Q: To survive‚ what gas do we need to breathe in? __________________________________ Q: Where is this gas produced

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

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 were

Temperature and Equilibrium Virtual Lab Change is influenced by many different factors in many different situations. If you imagine the 400‚000 gallons of water in a stream at the top of a hill‚ you can picture that they will flow down the hill in order to reach equilibrium. But what if the temperature outside is -40 degrees Fahrenheit? How might this change the movement of the water molecules down the hill? This virtual lab will allow you to explore how temperature changes affect two linked

environmental conditions affected the rate of transpiration of a plant. The environmental factors we looked at were the affects of various temperatures and different light amounts in the different temperatures. We found that as the temperature warmed up‚ the rate of transpiration was higher. When the temperature was at five degrees Celsius‚ the rate of transpiration was very low. When we took out half of the light source and measured the rate of transpiration in the three temperatures we found the same

BGY 2001 CONCEPT OF BIOLOGY Laboratory Report PRACTICAL 8 TRANSPIRATION Tittle: Transpiration Objectives: 1. To measure transpiration rates by using photometer. 2. To determine the factors that influences the rate of water loss from a plant through transpiration Introduction: Most of the water a plant absorbs is not used for a plant’s daily functioning. It is instead lost through transpiration‚ the evaporation of water through the leaf surface and stomata‚ and through guttation
