Basics of Plant Respiration
Tuesday, September 12, 2017 | Jose Chen Lopez
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.
They use the carbon dioxide (CO2) from the environment to produce sugars and oxygen (O2), which can later be utilized as a source of energy. While photosynthesis takes place in the leaves and stems only, respiration occurs in the leaves, stems and roots of the plant. The process of respiration is represented as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O + 32 ATP (energy)
As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration". In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.
Role of air temperature: Plant respiration occurs 24 hours per day, but night respiration is more evident since the photosynthesis process ceases. During the night, it is very important that the temperature is cooler than during the day because plants can experience stress. Imagine a runner in a marathon. The runner respires at higher rates than a person standing still; therefore, a runner’s rate of respiration is higher and the temperature of the body increases. The same principle applies to plants, as temperature at night increases, the respiration rate increases and consequently temperature increases. This action could result in flower damage and poor plant growth.
