FAQs on NCERT Solutions for Class 9 Chemistry Chapter -5 The Fundamental Unit of Life
1. What do Osmosis and Diffusion mean as per the fundamental unit of life class 9?
Osmosis is a process through which water moves in and out of the cell membrane. The movement is always from a region of higher concentration to lower concentration of water through a selectively permeable membrane until it reaches an equilibrium.
In a similar manner, diffusion refers to the process by which Carbon Dioxide moves in and out of the cell membrane. The cellular wall contains a high level of CO2, whereas the CO2 concentration outside is significantly low. This causes the CO2 to move from a region of higher concentration to that of low concentration to maintain a level of equilibrium.
2. What are the important topics in the Fundamental Unit of Life as per the NCERT Solutions?
The important topics that students must learn in the chapter fundamental unit of life are – Discovery of the cell, Unicellular organism, Multi-cellular organism, characteristics of the cell, structural organization of cell-like plasma membrane, nucleus, and cytoplasm, DNA, Chromatin material, Chromosomes, and proteins.
Apart from this, students must also focus on topics like Mitochondria, Plastids, lysosomes, chloroplast, leucoplast, vacuoles, Golgi apparatus, Ribosomes, Endoplasmic reticulum, and Cell organelles. Students should focus on learning the topics extensively. Diagrams of every structure and its parts should be learned in detail to answer MCQ, long answer and questions based on diagrams.
3. What is the difference between Prokaryotic and Eukaryotic cells as per the NCERT Solutions?
There are four main differences between Prokaryotic and Eukaryotic cells, which are largely related to their structures and size.
Prokaryotic cells are smaller in size, but Eukaryotic cells are bigger in general. The nucleoid is the nuclear portion of a prokaryotic cell that lacks a nuclear membrane. In comparison, the nuclear membrane of a Eukaryotic cell is strongly defined. Prokaryotic cells have a single chromosome, whereas Eukaryotic cells have many chromosomes. Membrane-bound cell organelles are not found in prokaryotic cells, but they are present in eukaryotic cells. Vedantu ch 5 science class 9 provides best practices to crack the exams.
4. How many questions are present under each exercise of the NCERT Solutions for Class 9 Science Chapter 5?

Tissues help in the functioning of these systems and processes like digestion, respiration, etc. in our bodies. This is why cells are referred to as the structural and fundamental units of life.
7. Who discovered the cell and how, according to as per the NCERT Solutions?
Robert Hooke, in 1665, discovered the cell. He was examining a thin slice of cork through a microscope when he observed its honeycomb-like structure. It seemed to comprise mini compartment-like structures. These structures were then called cells. To study more and learn through diagrams students can refer to vedantu website or the app. Vedantu offers best class 9 science chapter 5 question-answer practices to get expertise in the chapter.
8. Can NCERT Solutions help you in the overall preparation for Class 9 Science Chapter 5 for the exam?
Yes, The Fundamental Unit of Life class 9 questions and answers introduces students to crucial subjects and foundations that students must be familiar with in order to succeed in later courses. Students should thoroughly review what they have learned in school and take regular notes. Taking notes will help students learn and remember the material. Try to practise all of the questions in the NCERT textbook, as well as the supplementary problems in The Fundamental Unit of Life Class 9 PDF, which is available online at the Vedantu website. The PDF will also allow you to modify more quickly.
9. How does cell division contribute to growth and repair in multicellular organisms?
Cell division, particularly through mitosis, allows for the growth of tissues and organs by producing new cells. Additionally, it facilitates the repair of damaged tissues by replacing old or injured cells with new ones. Students can also visit other important resources of the fundamental unit of life provided by Vedantu.
10. How does the cell cycle ensure proper cell growth and division?
The cell cycle consists of stages like interphase (cell growth and DNA replication) and mitotic phase (cell division). It ensures that cells grow, replicates their DNA accurately, and divide properly, maintaining tissue integrity and functionality. Students can visit other resources of the fundamental unit of life class 9 questions and answers to boost their chapter knowledge.
