Life Processes Class 10 Important Questions for Board Exam

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.

Life Processes Class 10 Important Questions for Term 1 and Term 2

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.
