NCERT Solutions for Class 10 Science Chapter 5 Topics

5.1 What Are Life Processes?: Life processes are essential activities performed by living organisms in order to sustain their existence, expand, multiply, and interact with their environment. All living organisms, regardless of size or complexity, engage in life processes that are necessary for their survival.

5.2 Nutrition: Nutrients are essential to the functioning of organisms in order to provide them with the energy and materials they need to grow, repair and maintain themselves. This includes consuming nutrients, digesting them into simpler forms, absorbing them into cells, assimilating them into the structures of the organism, and excretion of waste products.

Subtopics covered in the section 5.2 Nutrition:

         5.2.1 Autotrophic Nutrition

         5.2.2 Hetrotrophic Nutrition

         5.2.3 How do Organisms obtain their Nutrition?

         5.2.4 Nutrition in Human Beings

5.3 Respiration: This is a process in which oxygen is taken in from the surrounding environment and carbon dioxide is released as a waste. Respiration is a cellular process that is essential for the production of energy through the decomposition of nutrients.

5.4 Transportation: Organisms require the movement of fluids containing nutrients, gases, waste products, and other substances within their bodies. These processes can include circulatory (in animals) and vascular (in plants) systems.

Subtopics covered in the section 5.4 Transportation:

         5.4.1 Transportation in Human Beings

         5.4.2 Transportation in Plants

5.5 Excretion: It is necessary to remove waste products and pollutants that accumulate in the body as a result of metabolic processes in order to avoid the accumulation of toxins that may affect the health of the organism.

Subtopics covered in the section 5.5 Excretion:

         5.5.1 Excretion in Human Beings

         5.5.2 Excretion in Plants

Key Features of Class 10 Science Chapter 5

• The movement of various species can be interpreted as a sign of life. 

• Maintaining life requires processes such as feeding, breathing, transporting materials within the body, and eliminating waste products. 

• Autotrophic nutrition is the consumption of simple, non-living materials from the environment and the synthesis of complex, high-energy organic materials from an external source such as the Sun. 

• Heterotrophic is the consumption of complex materials prepared by other organisms. 

• In humans, the food we eat is broken down in several steps along the digestive tract and the digested food is absorbed into the small intestine and sent to every cell in the body.

• The process of respiration involves the breakdown of organic compounds, such as glucose, into energy, which is then converted into ATP, which is used to fuel other reactions in the cell. This process, known as aerobic respiration or anaerobic respiration, increases the amount of energy that is available to the organism.

• In humans, the circulatory system is responsible for the transport of oxygen and other materials, such as carbon dioxide, food, and excretory products, through the heart, blood vessels, and vascular tissue. 

• In plants, waste material is disposed of through a variety of methods, such as storing it in cell vacuoles, removing it in leaves, or excreting it into the environment.

Frequently Asked Questions

Question 1: What is the primary goal of life processes?

Answer 1: The goal of life processes is to support the survival, growth and reproduction of living things by maintaining vital functions like nutrition, breathing, waste and reaction to stimuli.

Question 2: Explain the importance of digestion in animals? 

Answer 2: Digestion in animals is the process of breaking down complex food into simpler, easier to digest components that the body can absorb and use. This process supplies the body with energy and nutrients it needs to grow and thrive.
