What is respiration?

Respiration is the process by which organisms use oxygen and glucose to release energy from food. Through respiration, organisms are able to obtain chemical energy stored in molecules and use it to function. It is a key process in producing the energy necessary for sustaining life and performing physiological processes.

The two types of respiration in organisms. 

Respiration in organisms can be divided into two distinct types: aerobic respiration and anaerobic respiration. Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration takes place without oxygen. Both require a source of energy usually provided by glucose, although some microorganisms can use other compounds as energy sources. The products of both types of respiration are carbon dioxide and water, although there are some differences in the tempo of the reactions which can be outlined in the accompanying worksheet exercises

What role does the skin play in respiration? 

The skin plays an important role in respiration as it is the organ that releases heat, known as thermogenesis, which helps regulate body temperature. Through this process of thermoregulation, waste gases such as carbon dioxide are let out and oxygen from the environment is taken into the body. This process helps to maintain a stable internal environment and makes respiration more efficient.

What are the by-products of cellular respiration?

The by-products of cellular respiration in humans and other animals is carbon dioxide and water. In plants, the products of photosynthesis are oxygen and glucose which are used for respiration, resulting in the release of carbon dioxide and water. Other organisms such as bacteria may produce different by-products depending on their metabolic processes.

Respiration in organisms is a vital process that involves the exchange of gases between the organism and its environment. It is an essential process for the survival of all living organisms, including humans, animals, and plants. Class 7th students learn about respiration in organisms, its types, and the organs involved in the process.

Respiration is the process of inhaling oxygen and exhaling carbon dioxide. It is the process through which energy is released from food molecules, such as glucose, in the presence of oxygen. The energy is then used by cells to perform various functions, including growth, repair, and movement. Respiration is an essential process for all living organisms because it provides them with the energy required for their day-to-day activities.

Class 7 students learn about respiration in organisms and the various organs involved in the process. The respiratory system consists of organs such as the nose, trachea, lungs, bronchi, and diaphragm. The nose is the primary organ of the respiratory system, and it is responsible for filtering the air we breathe. The trachea, also known as the windpipe, is the tube that connects the nose to the lungs. The lungs are the organs responsible for exchanging gases between the body and the environment. The bronchi are two tubes that branch off from the trachea and lead to the lungs. The diaphragm is a sheet of muscle that separates the chest cavity from the abdominal cavity.

Class 7th students also learn about the different types of respiration, including aerobic and anaerobic respiration. Aerobic respiration is a process that requires oxygen, and it is the most common type of respiration. It occurs in the presence of oxygen, and it produces a large amount of energy. Anaerobic respiration, on the other hand, occurs in the absence of oxygen. It produces a small amount of energy and results in the production of lactic acid in animals and ethanol in plants.

Students also learn about cellular respiration, which is the process by which cells convert glucose into energy. It is a complex process that involves several steps, including glycolysis, the Krebs cycle, and oxidative phosphorylation. Glycolysis is the first step of cellular respiration, and it occurs in the cytoplasm of cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria of cells.

Class 7 students also learn about the differences between aerobic and anaerobic respiration. Aerobic respiration produces a large amount of energy and requires oxygen, while anaerobic respiration produces a small amount of energy and occurs in the absence of oxygen. Students also learn about the different types of respiration in plants, animals, and humans.

In addition to learning about respiration in organisms, class 7th students also learn about the different organs involved in the process, including the skeletal structures surrounding the chest cavity. They also learn about the breathing rate, which is the number of breaths taken per minute. The diaphragm is responsible for breathing, and it involves the movement of the ribcage and the diaphragm.

Class 7 students can find several resources to help them learn about respiration in organisms, including worksheets, notes, and question-answer sets. They can also find pdf files that provide a detailed explanation of the process, along with examples and illustrations. These resources can help students to understand the concept of respiration and its importance in living organisms.

In conclusion, respiration in organisms is a critical process that allows living organisms to produce energy required for their day-to-day activities. Class 7th students learn about the different types of respiration, the organs involved in the process, and the differences between aerobic and anaerobic respiration. By understanding the concept of respiration, students can appreciate

Respiration in organisms class 7 questions with answers (Extra)


  1. What is respiration?

Respiration is the process by which organisms inhale oxygen and exhale carbon dioxide, producing energy in the form of ATP.

  1. What are the different types of respiration?

There are two types of respiration: aerobic and anaerobic. Aerobic respiration requires oxygen, while anaerobic respiration occurs in the absence of oxygen.

  1. What is the difference between aerobic and anaerobic respiration?

The main difference between aerobic and anaerobic respiration is that aerobic respiration requires oxygen, while anaerobic respiration occurs in the absence of oxygen.

  1. What is cellular respiration?

Cellular respiration is the process by which cells produce energy in the form of ATP through the breakdown of glucose.

  1. What is the role of the diaphragm in respiration?

The diaphragm is a muscle that helps to control breathing by contracting and relaxing, which allows for the expansion and contraction of the lungs.

  1. What is breathing rate?

Breathing rate is the number of breaths taken per minute and is influenced by factors such as physical activity, stress, and environmental conditions.

  1. What is the trachea?

The trachea is the tube that connects the larynx to the bronchi and allows air to flow in and out of the lungs.

  1. What is the difference between inhalation and exhalation?

Inhalation is the process of breathing in air, while exhalation is the process of breathing out air.

  1. Why do all animals respire?

All animals respire to produce energy in the form of ATP, which is necessary for survival and metabolic processes.

  1. What is the purpose of respiration in plants?

Plants respire to produce energy in the form of ATP, which is necessary for metabolic processes such as photosynthesis and growth.

FAQs on Respiration in organisms class 7th CBSE


Q: What is respiration in organisms? A: Respiration in organisms is the process of exchanging gases between the body and the environment. It involves the uptake of oxygen and the release of carbon dioxide.

Q: What is the difference between aerobic and anaerobic respiration? A: Aerobic respiration occurs in the presence of oxygen and releases a large amount of energy, while anaerobic respiration occurs in the absence of oxygen and releases a smaller amount of energy.

Q: What is the breathing rate? A: Breathing rate is the number of breaths taken per minute. It varies depending on the activity level and health of an individual.

Q: What is the diaphragm? A: The diaphragm is a sheet of muscle located below the lungs that contracts and relaxes to help with breathing.

Q: What is the trachea? A: The trachea, also known as the windpipe, is a tube that connects the mouth and nose to the lungs, allowing air to pass in and out of the body.

Q: Why do organisms need to respire? A: Organisms need to respire to release energy from food molecules to perform life processes, such as growth, repair, and movement.
