HYPERLINK http//www.phschool.com/science/biology_place/labbench/lab5/intro.html http//www.phschool.com/science/biology_place/labbench/lab5/intro.html Click on the link above and answer the following questions in your lab notebook. Please write the section headings along with making sure you use full sentences in your responses. Introduction and Key Concepts What will you observe in this investigation Write the equation for cellular respiration. What are some processes in plants that require respiration Design of the Experiment What are the three ways in which you can measure the rate of cellular respiration What method will be used in this demonstration Sketch a respirometer and label its important features. What does it measure As the organism inside the respirometer consumes oxygen, what happens to the water What happens to the CO2 that the organism produces Experimental Setup (View the graphic), then create this data table in your notebook and fill it in.

(Show calculations) c) Based on the graph, would you conclude that non germinating seeds respire Extension A cricket is placed in a respirometer and data taken at three temperatures. The following table shows the data collected, create a graph.
