FAQs on The Cell - Cell Structure and Functions - Science - Class 8- Magnet Brains Video Lecture
| 1. What is the structure of a cell? |  |
Ans. The structure of a cell can be divided into two main parts: the cell membrane and the cytoplasm. The cell membrane is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell. The cytoplasm is a gel-like substance that fills the cell and contains various organelles, such as the nucleus, mitochondria, and ribosomes.
| 2. What are the functions of a cell? | |
Ans. Cells have various functions depending on their type and location in an organism. Some common functions of cells include providing structural support, carrying out metabolism, reproducing, and responding to stimuli. Additionally, cells can specialize in specific functions, such as nerve cells transmitting electrical signals or muscle cells contracting for movement.
| 3. How does the cell membrane function? | |
Ans. The cell membrane performs several important functions. It acts as a barrier, selectively allowing certain substances to enter or exit the cell. It also helps maintain the shape and structure of the cell. The cell membrane is made up of a lipid bilayer with embedded proteins that assist in transporting molecules across the membrane and transmitting signals from the outside to the inside of the cell.
| 4. What is the role of the nucleus in a cell? | |
Ans. The nucleus is often referred to as the control center of the cell. It contains the cell's genetic material, DNA, which carries the instructions for the cell's growth, development, and reproduction. The nucleus also regulates the activities of the cell by controlling the production of proteins necessary for various cellular processes.
| 5. How do mitochondria contribute to cell function? | |
Ans. Mitochondria are known as the powerhouse of the cell because they generate energy in the form of ATP through a process called cellular respiration. This energy is essential for the cell to carry out its functions. Mitochondria have their own DNA and can replicate independently within the cell. They are particularly abundant in cells with high energy demands, such as muscle cells.
