Question 46.
Name three life processes which are essential for maintaining life and briefly explain the functioning of any one of them. (CCE 2015, 2016)
Answer:
Nutrition, respiration, exchange of materials.
Nutrition: It is the process by which living beings procure food for obtaining energy and body building materials. Body building materials are usually carbon-based. The food sources are also carbon based. They are, of course, varied. Plants manufacture their own food in the process of photosynthesis. Animals obtain food from outside. Food obtained from outside is first broken down through digestion into simpler soluble substances for absorption. Inside the cells, the simple substances are converted into various complex biochemicals to form components of protoplasm. Some biochemicals function as respiratory substfates.

To prepare for the board exams and score good marks, students ought to practice CBSE Class 10 life processes with important questions along with the in-text questions after every section of the topic. In this article, we shall provide a list of life processes Class 10 important questions. Try to answer the questions in your language and gear up for the board exams.

Students can also take the help of NCERT Solutions for Class 10 Biology Chapter 6 to get the step-by-step explanation for every in-text question. Check the below table to revise the in-text life processes important questions Class 10:

Q1. What is the importance of life processes Class 10?
Ans. The life processes chapter Class 10 educates students about the importance of life-maintenance activities in plants and human beings and why students should know about these processes.

Q2. Where can I get life processes important questions Class 10?
Ans. Students can download important CBSE Class 10 questions on life processes from this article or by visiting embibe.com.

Q3. What are the types of life processes?
Ans. There are seven important life processes namely movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.

Q4. Why is respiration an important life process?
Ans. Respiration is is the process of releasing energy by breaking down food. It is an important process that provides energy for performing various life processes needed to keep organism alive.

Life processes are processes which are required to maintain body functions and are necessary for survival. The important life processes are nutrition, transportation, metabolism, reproduction, respiration, and excretion. All these processes work together and result in the growth and development of the body. For example, nutrition is the process by which we take up nutrients which are used by the cells to meet their respective needs. This is a vital process which helps living beings to obtain their energy from various sources. Respiration is associated with the exchange of gases as well as burning of food. It results in the breakdown of glucose and release of oxygen. Similarly, cell cycle and cell division play an important role in the growth and development of the organisms. They help in the formation of new organisms as well as repair of dead and damaged cells and tissues.

Extramarks is the most trusted platform where students get handy study notes for their studies and exam preparation from Class 1 to Class 12.

Question 1.
What is a living being?
Answer:
An individual form of life that consists of a single cell or a complex of cells in which cell organelles or organs work together to carry out the various basic processes of life is called a living being.

Question 4.
What are life processes? Name some of the basic life processes.
Answer:
The basic activities that take place in the body of organisms, which keep them alive and help to maintain their body are known as life processes. The basic life processes include nutrition, respiration, transport, digestion, excretion, reproduction etc.

Question 5.
What criteria do we use to decide whether something is alive?
Answer:
Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements that are not visible to the naked eye. The presence of life processes in the body helps us decide whether something is alive or not.

Question 6.
What processes would you consider essential for maintaining life?
Answer:
The processes that perform the maintenance function of living organisms are called life processes. All life processes such as nutrition, respiration, transportation, excretion, control and coordination are essential for maintaining life.
