Plant respiration is a process and for this, they require oxygen and they return carbon dioxide. The movement of air between the atmosphere and cells of the species is seen. The process witnesses the inhalation of oxygen and exhalation of carbon dioxide gas. Parts for the respiration of plants are leaves, stems, and roots.
The process of respiration is considered a biochemical process that helps living organisms to get the required energy. Glucose is an essential element for starting this process and it is diverted into energy that helps in the production of carbon dioxide and water. It is called a method that helps the cells to get chemical energy.
They consume oxygen and liberate CO2 and this process is known as respiration. In the case of plants, the respiration process executes through the parts like stem and root. The matter is clear that this process uses oxygen for the production of carbon dioxide. The process is written in a way like
“Oxygen + Glucose → Water + Carbon Dioxide with Energy”
The most essential part of a plant is the root and it is the underground part of a plant. It helps in consuming oxygen from the gaps of the particle lies in the soil. This consumed oxygen is used for the transportation of minerals and salts from the soil. In the process of respiration, plants liberate carbon dioxide and that is the reason people are hindered to go under a tree at night.
The process is very important for plants as it helps them in getting energy. Root hairs plays an important role here as it helps in consuming oxygen from the soil particles. It is seen that respiration occurs in the daytime as well as at night and they form carbon dioxide.
In the respiration process of stems, stomata plays an important role. The exchange of gases is occurred in stomata and it helps in diffusing the air. In the case of the plants having woody stems, the exchange of gases occurs in the lenticels. Here, lenticels are nothing but cells that are dead and present in the woody plants.
They help in the passing of oxygen and in the liberating of carbon dioxide. This is the process of respiration in stems and it helps the plants in getting chemical energy.
Leaves are considered the effective parts of a plant and they are responsible for the process of photosynthesis. The presence of stoma in the leaves is responsible for the exchange of respiratory gases occurs through very small pores. It is situated on the backside of the plants and each of them consists of a tiny pore at the centre.
These parts are regulated and enclosed by the guard cells and the diffusion method is important here. The opening of stomata helps in the exchange of gases between the atmosphere and interior of the leaf and it happens due to this method of diffusion. Thus, the process of respiration in leaves is completed with the help of stomata.
Biology gives the description of two types of respiration systems and they are Aerobic Respiration and Anaerobic Respiration. The division is done based on the presence and absence of oxygen. Here, aerobic respiration occurs due to the presence of oxygen. Oxygen helps here to break the chemical bonds in glucose to liberate energy in high volumes. It is considered the main source of energy for plants.
In contrast, the process of respiration that occurs in the absence of oxygen is called anaerobic respiration. The process is responsible for the oxidation of foods that is incomplete and it is made with the help of alcohol and carbon dioxide. It also produced different organic matters like lactic acid, oxalic acid, and citric acid.
Although it is seen that photosynthesis and respiration are connected to each other, there are some dissimilarities between these factors. They have been presented through a box below
It happens in the presence of sunlight during daytime.
This process continues through the lifetime
| Photosynthesis | Respiration |
|---|---|
| The green plants having chlorophyll pigments go through this process. | Respiration is seen among the living beings like birds, animals, and plants. |
| Here food is synthesized. | Food is found in the form of oxidised. |
| It stored energy. | This process released energy. |
| This process is called an anabolic process | It is known as a catabolic process. |
| A needed particle is cytochrome. | It also needs cytochrome. |
| This process is called the Endothermal process. | It is famous as the Exothermal process. |
| Products like sugar, Oxygen and water are found here. | Hydrogen and carbon dioxide is found here. |
| Potential energy is formed from the radiant energy. | Kinetic energy is formed from the potential energy. |
The respiration of the plants shows that they inhale oxygen and exhale carbon dioxide. Stomata is important for this process, it is seen in the leaves, and lenticels is found in stems. The important parts of respiration are leaves, stems, and roots. It gives energy to the plants for their survival and the plants' respiration process is known as Cellular respiration.
Q1. What is Aerobic Respiration?
Aerobic Respiration is the kind of respiration which happened in the presence of oxygen. Here oxygen is required to break the chemical bonds in glucose to liberate energy in high volumes. It is considered the main source of energy in plants.
Q2. What is Anaerobic Respiration?
Anaerobic Respiration is the type of respiration that happens in the absence of oxygen. It witnesses the incomplete oxidation process of the food substances like alcohol and carbon dioxide.
