FAQs on PPT: The Fundamental Unit of Life - Science Class 9
| 1. What is the fundamental unit of life? |  |
Ans. The fundamental unit of life is the cell. Cells are the basic structural and functional units of all living organisms. They carry out essential processes necessary for life, including metabolism, growth, and reproduction.
| 2. What are the main types of cells? | |
Ans. The main types of cells are prokaryotic cells and eukaryotic cells. Prokaryotic cells are simple and do not have a defined nucleus or organelles, while eukaryotic cells are more complex, containing a nucleus and various membrane-bound organelles.
| 3. What is the difference between plant cells and animal cells? | |
Ans. Plant cells differ from animal cells in several ways. Plant cells have a rigid cell wall made of cellulose, chloroplasts for photosynthesis, and large central vacuoles for storage. Animal cells, on the other hand, lack a cell wall and chloroplasts and usually have smaller vacuoles.
| 4. What are the functions of the cell membrane? | |
Ans. The cell membrane serves several important functions. It acts as a barrier, protecting the cell's interior from the external environment. It regulates the movement of substances in and out of the cell, facilitating communication and transport through proteins embedded in the membrane.
| 5. Why are mitochondria known as the powerhouse of the cell? | |
Ans. Mitochondria are known as the powerhouse of the cell because they are responsible for producing adenosine triphosphate (ATP), the energy currency of the cell, through the process of cellular respiration. This process converts nutrients into energy that cells can use to perform their functions.
