Life Processes Class 10 Important Questions: Biology is one of the core subjects among the three Science subjects for Class 10. ‘Life processes’ is the 6th chapter in the NCERT Class 10 Science textbook. This chapter educates students about the definition and kinds of life processes occurring in plants and human beings.
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.
As per the latest CBSE guidelines, the CBSE Class 10 exams occur in two terms – term and term 2. The CBSE Biology Chapter 6 Life Processes falls under the unit of World of Living and falls under the Term 1 syllabus. This chapter carries 10 marks.
However, to encourage deep understanding of the subject, we shall provide a list of important questions from life processes MCQ term 1. The term 1 questions shall include Life Processes MCQs for practice while the term 2 important questions shall include, 2 marks, 3 marks, 4 marks short and long answer questions.

There are several benefits of solving life processes important questions 2022. Let us look at some of them below:
Students can check the below frequently asked questions on life processes important questions:
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.
Q5. Why are plants called autotrophs?
Ans. Plants are called autotrophs because they prepare their own food.
Now that you have the list of important questions for CBSE NCERT Biology Chapter 6, we suggest to you to also go through the CBSE Class 10 sample papers and CBSE Class 10 previous year question papers. Additionally, to deepen one’s chapter-wise conceptual clarity and learn a variety of questions, students can opt for Embibe’s practice tests and test overall learning progress by attempting mock tests for 10th Class students.
