Summary Introduction

To compare: The roles of CO2 and H2O in cellular respiration and photosynthesis.

Concept introduction: Respiration is a chemical process through which plant cells release energy from food molecules and provide energy essential for life. The respiration can be aerobic with oxygen and anaerobic respiration in the absence of oxygen is termed as cellular respiration. The term photosynthesis is used by plants and other organisms to convert light energy from sunlight into chemical energy and result in the transformation of energy.

Explanation of Solution

Photosynthesis is a process to synthesize carbohydrates. In this process of synthesis, it needs water (H2O), carbon dioxide (CO2), and energy (photons). It takes place in two stages, the first of which captures the energy, and the second that makes sugars. The first stage requires H2O because the plant uses the hydrogen atoms in water to collect the energy. In the second stage, the sugar obtained contains carbon, oxygen, and hydrogen, of which the first two come from CO2 and the last comes from H2O. In cellular respiration, sugar molecules are split into CO2 and H2O, and for this process, adenosine triphosphate (ATP) is made that can then be used for cellular work. This process occurs partially in the cytoplasm and mitochondria.

E. Bar Graph Use the same technique to upload the completed image. We will use a different type of graph to derive additional information from the CO2 data (Fig A1.6.2) 1. Calculate the average rate of increase in COz concentration per year for the time intervals 1959-1969, 1969- 1979, etc. and write the results in the spaces provided. The value for 1959-1969 is provided for you as an example. 2. Plot the results as a bar graph. The 1959-1969 is plotted for you. 3.
