What is Respiration in Plants? Definition, Meaning, Equation, Process


In this article, we will learn what is the respiration of plants, along with the definition, meaning, respiration process, the role of oxygen & carbon dioxide, etc.

Let’s explore!

What is Respiration in Plants? Definition

Respiration allows living beings to breathe properly without creating any obstacles. All the surviving creatures have a respiratory process that helps them breathe and survive for a more extended period.

In this article, we will discuss the respiration process and relevant information elaborately.

Respiration of Plants Definition

“Respiration” is the prior process that living beings require to survive. This is a fact that if we don’t breathe in a single minute, we will die. All the living beings surviving in this world need the Respirator to Breathe.

  • This process enables us to take the oxygen inside and carbon dioxide outside.
  • All the living organism body has the Respiration process.
  • The respiration process in all living beings must be conducted fluently.
  • If the process faces difficulty, then it can be life risks and threats for surviving.

Food, Energy, and Respiration

We all know that living organisms require food to stay alive. Food helps to retain energy and plays an essential role in conducting several activities. When living beings receive food, they convert it into energy, and it helps them to breathe.

In this context, we will understand how the Respiration process takes place in plants.

Do Plants Breathe Yes or No?

The answer is a big ‘YES’. Plants also breathe like us, like animals.

We, human beings, take oxygen from the air and return carbon dioxide to the atmosphere and this process continues. In the same way, plants also take oxygen to respire and leaves carbon dioxide into the atmosphere.

We have lungs which help to exchange the gases but plants don’t have anything like lungs. They have stomata and lentils which take parts in the gaseous exchange or respiration.

  • Stomata stay in the leaves
  • Lentils stay in the stem

Now, what do you think breathing & respiration are the same? Not really! Breathing is one process in respiration. Plants breathe differently than human beings.

  • They use their cellular respiration technique to survive.
  • They create glucose by photosynthesis and use that energy during the respiration process.
  • As plants breathe normally at night, it is not recommended to sit below plants to avert carbon dioxide reach the air.
  • Many scientists research the plant’s breathe and confirmed that it’s true.

We will learn all about the plant’s respiration process.

Respiration in Plants

“Plants” are an essential part of this planet. We cannot imagine our planet without plants. If there is no green, then everything will look dull and without life. We need to understand that to see these green and plants need to live. The destruction of plants has already taken a rapid pace, so saving the lives of the plants is way necessary.

Process of Respiration in Plants?

The plant that survives or grows undergoes a respiration process.

From the Word Respiration in plants, we understand that the process must help the plants to breathe.

All the living organisms surviving in this world require energy to carry the daily basis activities. The performance of any activity without proper energy is impossible.

Similarly, the plants are the ones amongst others that breathe, and to breathe, they go through different processes to get their food. Plants make their food with the help of sunlight, and the process of making food is known as “Photosynthesis.”

Role of Oxygen & Carbon Dioxide in Respiration Process

The values of the plants are worth it as it takes all the carbon dioxide inside and provides oxygen in the air for breathing.

  • Oxygen is the pure gas that mixes in the air, and we people inhale it to survive and live.
  • The ecosystem activities remain balanced for a longer time when plants are there, and more plantation helps in easier ecological balance.
  • O2 symbolizes oxygen, and CO2 symbolizes Carbon Dioxide. We all know this; clearly, people release carbon dioxide while breathing and inhales only oxygen.
  • This process itself reveals how much oxygen s having importance in people’s lives. If there is no oxygen on the planet, then everything will be lost—no greenness, happiness, or color.
  • Plants are a life-giving source to humans and bring colors to nature. It has to be kept well, and efforts should be given for its maintenance.

Different Parts that help in Respiration of Plants

If we go through different contexts and scientific studies, it has not been proved that plants breathe. Breathing in plants has not been easily shown, and we also cannot see them breathing directly.

  • Animals, humans, and other living organisms can be seen breathing directly, but we cannot get so for plants.
  • We understand that plants grow. Right from being the tiny plant, it gradually turns to the big trees after a few years.
  • Anything that grows certainly requires a huge amount of energy, and for that, they need to breathe. This growing process in plants lets others understand that it is breathing and gaining all the energies, helping it grow.
  • The growing process in plants has different aspects and understanding, and in this context, it will be understood the process taken place during the growth period in plants.

Now, let’s learn the respiration process in roots, stems, leaves, plant cells, in brief. However, before that, we will see the equation in respiration plants.

Respiration in Plants Equation

Let’s see the formula of the equation in the respiration of plants. We have learned that in the respiration of plants, glucose is broken into carbon dioxide and water.

The equation of respiration in plants becomes,

  • Glucose + Oxygen → carbon dioxide + water + energy
  • C6H12O6 + 6O2→6CO2 + 6H2O + Energy

Roots and Respiration Process

Roots are the base of plants and trees. It conducts different functions of the Trees parts. To support the roots, mud and the soil plays an important role.

The following are the points that justify the same:

  • The fertile soil helps the roots stay strong, and due to this, Trees grow at an increasing rate. Fertility of soil is necessary for this process. If the soil is not fertile, then the trees cannot stay physically powerful.
  • The roots of the plants are crucial and hold the plants and trees from underneath. We have seen trees that have been surviving for more than decades. The reasons behind this are the strong roots of the plants.
  • It grows in the downward direction and gets spread under the ground simultaneously.
  • When the roots of the plants are not stronger, the trees face difficulty in growing continuously and can get dry during a short period.
  • It grows under the ground and gets spread when proper maintenance is provided.
  • The strong roots of the plants depend on many factors.
  • The roots require water daily or frequently. When the root gets water, it absorbs it and helps it to grow more and stay strong.
  • The roots of the plants and trees vary from each other. Small plants have small roots and limit their growth at a certain period. The big trees roots keep on growing, and this provides proper growth to the trees.

Stems and Respiration Process

Stems also take part in the respiration process. Let’s see it in brief,

  • We have already learned that plants take oxygen from the air. In this case, oxygen is diffused into the plant stem through the stomata.
  • After that this oxygen is transferred to other parts of the plant.
  • After that, carbon dioxide is produced due to the respiration process and released to the atmosphere through the stomata by the diffusion process.

Leaves and Respiration Process

We have already learned that leaves also take part in the respiration process.

  • If you observe any leave by a microscope, you will see that each leave is consists of myriads of small pores.
  • These pores are simply stomata.
  • Oxygen or carbon dioxide exchange happens through these pores or stomata.
  • There are guard cells across the stomata.
  • These guard cells help to open and close the stomata.
  • Like respiration in steam, here also, the gaseous exchange happens due to the diffusion process through the stomata.

Plant Cells and Respiration Process

All living beings consist of small cells. Cells’ roles are to help the living organisms safe and produce energy to conduct different valuable activities.

  • Similarly, Plants also have cells that are made up of small particulars.
  • The plant’s cells are called “Eukaryotic cells.”
  • The plants’ cell keeps away the small microbes such as bacteria and fungi as well if these microbes attack plants that the plants can die easily.
  • Every organism needs protection and wants to remain safe. Similarly, cells are the ones that are responsible for keeping the organisms safe and living for a longer period.
  • The cell of all the living organisms helps get the energy and enable to get all the nutrients required for living.
  • The cells inside the plants also have different compositions, and it is not similar to the types of cells found in animals or humans.
  • The cells of the plants are quite bigger compared to the cells of Animals.

Green Plants & Importance 

In today’s environment, green plants are vital, and their maintenance is also essential. We call the plants alive when it is green. The green plant gives the overviews that it is growing and gives oxygen.

  • To remain green, plants need a lot of maintenance and effort.
  • Water is the most crucial source for plants to live. We have seen this daily, that the plants that are watered daily remain green for a longer period.
  • In forests, the only source of water is rain. So, rain is also significant because it gives life to the forests and helps them grow faster and remain green.
  • The requirement of oxygen is too much as we all living beings relied on that. But the problem faced in today’s environment is that forests are being cut and plants are less planted.
  • The fewer plantations of Trees and more depletion of forests have led to increased carbon dioxide and a decrease in oxygen.
  • The problem of oxygen is not good for any living organisms because it can take life.
  • Plants grow naturally, and it is a natural gift by nature to all living beings. It increases the beauty of nature and also certainly is the life provider.
  • Henceforth, maintaining the greenness of the plants is very necessary and worth it.
  • The roots of the plants need to be fully strong. The strong roots of trees and plants keep them alive for years until a human does not destroy them.

Difference Between Respiration and Photosynthesis

Let’s see the simple diagram of Respiration and Photosynthesis.

Let’s see the differences between respiration and photosynthesis, as follows:

RespirationPhotosynthesis
The respiration process occurs in all plants irrespective of green plants, all animals, birds, etc. to all living things.The photosynthesis process occurs in all green plants which consist of chlorophylls.
In this process, light is not mandatory.In this process, light is mandatory.
Here, food is decomposed or broken down. Plants decompose glucose.Here, food is made. Plants made glucose.
Energy is released into the atmosphere.Plants stored energy in this process.
The plant takes O2 from the atmosphereThe plant gives O2 to the atmosphere
Plant release CO2 to the atmosphereThe plant takes CO2 from the atmosphere
Cytochrome is essentialCytochrome is essential
Equation of Respiration of Plants is C6H12O6 + 6O2→6CO2 + 6H2O + EnergyEquation of Photosynthesis is 6CO2+6H2O + Energy (Light)→C6H12O6 +6O2
This process is an Exothermal process.This process is the Endothermal process.
This is one form of metabolismThis is also one form of metabolism
Lifetime processThe process occurs in the daytime only
The respiration process is basically a catabolic processThe photosynthesis process is an anabolic process
Potential energy kinetic energy.Radiant energy potential energy.

Important Facts about Plants

More and more scarcity of natural resources and increased population have led to an increase in agricultural activities. Agriculture activities are appreciated, but the sad fact is that most trees and forests get destroyed to carry away this process.

  • Farmers are fully dependent on agriculture, and when they get this opportunity to grow crops. Without any second thought, they get into their work, and most of the trees get removed.
  • Also, after that, they bring their cattle for the gazing. The land on which gazing takes is done continuously by the cattle; it gradually becomes barren.
  • The barren lands then have no fertile soil, and neither can they be used for agricultural activities nor plantation. In this way, we lose the worth of both plants and land.
  • Forests are destroyed daily. For only continuing the development process, most of the forests get cleared out.
  • Plants are used excessively for medicines.

Summary

The phenomenon of Respiration enables living beings to breathe. Breathing is a vital ad concerned process that cannot be left. The overall concept explains the importance of the existence of plants. The plants are oxygen providers, but it is also the producer of both fruits and vegetables.

Plants are also used for making medicines, and those can be used to cure all health-related issues. From the overall context, it can be concluded that plants are boon to us, and we should not destroy them at any cost.
