1. What is plasma membrane? What are their functions? Ans: Plasma membrane also called as cell membrane, is the outer covering of a cell that separates the cell contents (protoplasm) from the surrounding medium. It is made up of proteins and lipids. It gives form (shape and size) to the cell It maintains the individuality of the cell (i.e. seperates cells) It keeps the cell contents in place 2. What are cell organelles ? Ans: The certain specific living parts of a cell with a definite function are celled Cell organelles. All cell are found to have same organelles and together these constitute to the basic unit of life. 3. What is cellulose and its functions? Ans: Cellulose is the main component of a plant cell wall. It is responsible for giving structural shape to the cell and also to protect the protoplasm. 4.  What is a Prokaryotic cell? Give an Example. Ans: The cells that do not hav...

IX Biology:Extra marks Guess Solved Question paper : Cell and its Function

Image
IX The Cell & Fundamental Unit of life Question :    Why is the cell known the 'fundamental and structural unit of life ' Ans: ell is called as the structural and functional unit of the living organism because it the smallest living entity that is capable of an independent existence. Separated cell organelles cannot be said to be living and are not capable of independent existence. Question :  what is a semi permeable membrane? what are the differences between semi permeable membrane and selectively permeable membrane? Ans: a semi permeable membrane is a membrane that allows only the entry of substances that are helpful for the body. a semi permeable membrane is also called a selectively permeable membrane. Question :     Which cell in the human body does not have the mitochondria? Ans: Mature erythrocytes don't have mitochondria Question :   What are plastids? Write their functions? Ans: Plastids are double membrane organelle...
