Question: How does an Amoeba obtain its food?
Answer
: Amoeba is a unicellular organism. It acquires its food through the false feet called “pseudopodia”. Whenever it locates a food particle it engulfs the food by its flexible protruding membrane. This food is broken down into simpler form by the food vacuole which contains digestive enzymes. This process is known as endocytosis.

Question: What is osmosis?
Answer
: Osmosis is the displacement of water molecules from a region where they are in higher concentration to a region where they are in lower concentration, through a partially permeable membrane.

A dilute solution contains a high concentration of water molecules, while a concentrated solution contains a low concentration of water molecules.

NCERT Solution for Class 9 Science Chapter 5: Chapter Description

The CBSE Science Class 9 Chapter 5 covers everything related to the Fundamental Unit of Life, that is, cell. Cells are enclosed by a plasma membrane composed of lipids and proteins. The cell membrane is an active part of the cell. It regulates the movement of materials between the ordered interior of the cell and the outer environment. In plant cells, a cell wall composed mainly of cellulose is located outside the cell membrane. Most plant cells have large membranous organelles called plastids, which are of two types – chromoplasts and leucoplasts. Cells in organisms divide for growth of body, for replacing dead cells, and for forming gametes for reproduction.

The NCERT Class 9 Science Chapter 5 deals with the study of the very basic entity of life which is a living cell. The chapter starts with an activity of preparing slides of onion peels and viewing them under a microscope. This practical example will help students visualise a cell. They can then read about plant cell and animal cell. The discussion moves on to the structural organization of a cell. Under this, students study the different cell organelles – plasma membrane or cell membrane, cell wall, nucleus, cytoplasm, nucleus, and other cell organelles. The endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, plastics, and vacuoles will also be discussed.

At the end of the chapter, students will learn about cell division – mitosis and meiosis and their significance. To score good marks in CBSE Class 9 Science exams, students must ensure they solve as many make CBSE Class 9th sample papers as they can, along with previous year’s questions.

The NCERT Solutions for Class 9 Science provide detailed explanation about various topics in simple language. It helps students understand the various complex topics easily. By solving the in-text exercise questions, students can prepare efficiently for the Class 9 annual exams.
