NCERT Solutions for class 10 Science Chapter 6 – Life Processes
In the chapter, Life Processes, we get to learn about various factors that contribute to a being for its living. The chapter briefly discusses the different processes that are required to maintain and sustain life such as respiration, nutrition, transportation of materials and excretion of the digested food. The various modes of nutrition are discussed in detail such as autotrophic and heterotrophic nutrition. A brief idea about the human digestion process right from the ingestion of food, food passage through the alimentary canal, food absorption, until the stage when digested food is ready to be excreted is explained.
Through this chapter, students are also enlightened with the process of respiration (which can either be aerobic or anaerobic) from inhalation to the breakdown of organic compounds due to the supply of energy in the form of ATP. In humans, the process of transportation of substances such as food, carbon dioxide, oxygen, and other materials is carried out by the circulatory system which is explained. The various constituents of the circulatory system such as blood, blood vessels, and the heart are also briefed.
The diverse functions of the excretory organs and its structure, in abstract, are shed light upon in this chapter. It also covers excretion in plants and the techniques plants use for excretion of waste products.

Frequently Asked Questions on Life Processes
Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans ?
Multi-cellular organism’s like humans have very big body and require a lot of oxygen to diffuse into body quickly in order to meet the oxygen requirement. Diffusion is a slow process which will take a lot of time to circulate oxygen to all the body cells. Because of its slow nature diffusion is insufficient to meet the oxygen requirements of multicellular organisms like humans.
What criteria do we use to decide whether something is alive ?
Walking, breathing, growth and other visible changes can be used to determine whether something is alive or dead. However some living things will have changes that are not visible to our eye; Hence, presence of life process is a fundamental criteria to decide whether something is alive.
What are outside raw materials used for by an organism ?
Outside raw material is used by organism for food and oxygen. Raw materials requirement varies on the complexity of the organism and the environment it is living.
What processes would you consider essential for maintaining life ?
Life processes such as respiration, digestion, excretion, circulation and transportation are essential for maintain life.
What is the role of the acid in our stomach ?
HCL present in the stomach dissolves food particles and creates an acidic medium. In acidic environment protein digesting enzymes pepsinogen is converted into pepsin. HCL in the stomach also acts as protective barrier against many disease causing pathogens.
What is the function of digestive enzymes ?
Digestive enzymes breaks the complex food molecules into simpler ones. This will make the food absorption process easy and effective. Absorbed food is transported to all parts of the body by blood.
How is the small intestine designed to absorb digested food ?
Small intestine has small projections called as micro villi which increases the surface volume which make absorption more effective. Within the villi there are numerous blood vessels that absorb digested food and carry it to blood stream. Blood transports food to each part of our body.
What would be the consequences of a deficiency of haemoglobin in our bodies ?
Hemoglobin is a protein responsible for transportation of oxygen to the body cells for cellular respiration. Deficiency of Hemoglobin can affect the oxygen carrying capacity of RBC’S. This lead to lack of oxygen in our body cells. Hemoglobin deficiency leads to a disease called as anemia.
