Content: Therefore: Light color + light intensity + surface area of plant exposed to light = chemical energy potential. We’ll be covering a great deal more information on light later in the book so let’s leave that one there for now. Carbon dioxide and rate of photosynthesis
Light provides the energy for photosynthetic pigments to convert carbon dioxide (CO 2) and water into sugars and oxygen. As light intensity increases, up to a point where the machinery of photosynthesis – the chloroplast – can no longer convert the light into chemical energy, the amount of sugar increases and thus, more energy is available for plant growth and maintenance. However, the concentration of CO 2 also influences photosynthesis in a dramatic way. To simplify things somewhat, plants consume CO 2 and release oxygen during the day as part of the process of photosynthesis (carbon dioxide + water → sugar + oxygen). At night they consume oxygen but don’t release oxygen. Instead they release CO 2 as part of the process of respiration (sugar + oxygen → carbon dioxide + water). Therefore, plants require CO 2 during the day for photosynthesis and oxygen at night for respiration.
