Photosynthesis uses those products from cellular respiration as its reactants and in turn produces glucose and oxygen- the reactants needed for cellular respiration.
The non-germinating peas produced rates close to zero for both photosynthesis and respiration (means were -0.331 ppm/min/g and 0.021 ppm/min/g, respectively). However, rates of photosynthesis and respiration varied for the germinating peas (means were 1.793 ppm/min/g and 18.191 ppm/min/g respectively).
Difference between Respiration and Photosynthesis | …
Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules.
Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.
How Are Photosynthesis & Cellular Respiration Related…
The differences in photosynthesis and respiration in germinating and non-germinating peas may help us explain the adaptations plants have made to be successful organisms. Many plants generate seeds to produce their offspring and within these seeds is the genetic information they need to become mature, reproductive plants. Since these seedlings begin without roots to acquire nutrients or leaves to generate energy, an investigation into a seedlings metabolic processes may provide insight into how a seed initially survives to maturity. Therefore, if germinating peas require energy to grow and we compare photosynthesis and respiration rates between germinating and non-germinating peas then we should see higher rates of respiration and photosynthesis in the germinating peas.
The Link between Photosynthesis and Cellular Respiration
And to reward you for reading through all that, here's a cute little song I found on youtube about the relationship between cellular respiration and photosynthesis.
