Important topics covered in the chapter Life Processes-
I
The chapter covers the important aspects of life processes such as photosynthesis, respiration, and digestion. It also discusses the important role of water in the life processes and the importance of nutrients for the survival of organisms.
Basic Life Processes
There are many basic life processes that are necessary for an organism to live. Examples of some basic life processes are breathing, eating, and sleeping. All of these processes are necessary for the organism to take in the nutrients it needs to survive and grow, to get rid of waste products, and to rest and rejuvenate.
Nutrition
and Dietetics
A nutritionist is a professional who is trained to provide dietary advice and counseling. Dietetics is the science of food and nutrition. A dietitian is a nutritionist who has completed a dietetic program and has been certified by the Commission on Dietetic Registration.
Transportation
Transportation refers to the process of transporting goods and people from one place to another. It can be done via various methods, including road, rail, air, and water. Transportation is an important part of the economy, and it helps to connect people and businesses to each other.
Metabolism
is the sum of all chemical reactions that occur in an organism to maintain life.
The chemical reactions that make up metabolism can be divided into two types: catabolism and anabolism.
Catabolism is the breakdown of larger molecules into smaller ones, while anabolism is the build-up of larger molecules from smaller ones.
Metabolism is necessary to sustain life because it provides energy for the cells and allows the organism to grow and reproduce.
Anabolism
is the metabolic process that synthesizes complex molecules from simpler ones. The anabolic process consumes energy in the form of ATP. This energy is used to form new molecules from the building blocks of proteins, nucleic acids, and lipids.
Catabolism
is the process that breaks down complex molecules into their component parts so that they can be used in energy production or other essential biochemical processes. In catabolism, the large, complex molecules are first broken down into smaller molecules, and then these smaller molecules are further broken down into even smaller molecules. The process of catabolism releases energy, which the body can use to power its essential functions.
Anabolism, by contrast, is the process that builds complex molecules from their component parts. In anabolism, the smaller molecules are first brought together to form larger molecules, and then these larger molecules are further assembled into even larger molecules. The process of anabolism requires energy, which the body gets from food.
Respiration
The respiratory system is responsible for bringing oxygen into the body and getting rid of carbon dioxide. The lungs are the main organ of the respiratory system. They are located in the chest cavity and are surrounded by a protective cage of ribs.
The lungs are filled with tiny air sacs called alveoli. When you breathe in, the air sacs fill with oxygen. When you breathe out, the air sacs fill with carbon dioxide. The carbon dioxide is then carried away by the blood.
The respiratory system is also responsible for the voice. The voice is produced when the vocal cords in the throat vibrate.
Reproduction
This species is oviparous.
Conservation
The IUCN has listed this species as being of “Least Concern” because it is a common species with a wide distribution.
Excretion
The kidneys excrete urine, which contains the waste products of metabolism. These wastes include urea, ammonia, and creatinine.
