Chapter 10 Respiration in Organisms Class 7 Science NCERT Solutions PDF

Chapter 10 is called “Respiration in Organisms,” and it is all about breathing, why breathing is important, and a few other ideas related to breathing. In the first part, we talk about why we breathe. This section explains things like “cellular respiration” and “where cellular respiration happens.” Chemical equations show how food breaks down with and without oxygen. 

Anaerobic respiration is talked about in situations like when food breaks down and when muscles work. The chapter “Respiration in Organisms” talks about how organisms breathe and how they take in and let out the air. This activity helps you understand how the rate of your breath changes in different situations.

Chapter 10 Respiration in Organisms NCERT Solutions for Class 7 Science – Important Notes

Here are some important things that are talked about in the chapter.

[adinserter block=”2″]

• Living things need to breathe in order to stay alive.
• Cellular respiration is the process by which food is broken down in the cell to make energy. Cells in all living things breathe. This is called cellular respiration.
• Aerobic respiration is the process by which glucose is broken down with the help of oxygen. Without oxygen, food can also be broken down. This kind of breathing is called anaerobic.
• There are some organisms, like yeast, that can live without air. They don’t need air to live. They get their power from breathing without oxygen.
• When you breathe, you take in oxygen-rich air and let out carbon dioxide-rich air with the help of your lungs. Inhalation is when the body takes in oxygen-rich air, and exhalation is when it lets out carbon dioxide-rich air. It is a process that goes on all the time and lasts as long as the organism does.
  • The breathing rate is the number of times a person breathes in one minute.
• How we breathe:
  • When we take a breath in, air goes through our nostrils and into the nasal cavity. 
  • Air comes in through the nose and goes down the windpipe to the lungs. 
  • In the chest area, there are lungs. The sides of this space are made up of ribs. 
  • The floor of the chest cavity is made up of a large sheet of muscle called the diaphragm. 
  • The diaphragm and rib cage have to move when you breathe.
• A cockroach’s body has small holes on the sides. Spiracles are the name for these holes. For gas exchange, insects have a network of air tubes called tracheae.
  • When you touch an earthworm, its skin feels wet and slimy. They are easy for gases to move through.
• Fish have gills that help them get oxygen from the water. There are a lot of blood vessels in the gills, which helps them exchange gases.
• Just like the rest of the plant’s living cells, root cells need oxygen to make energy. Roots get the air they need from the spaces between soil particles.
