FAQs on Detailed Explanation: Cell: The Unit of Life Video Lecture - Biology A-Level - A Level
| 1. What is a cell and why is it considered the unit of life? |  |
Ans. A cell is the basic structural and functional unit of all living organisms. It is considered the unit of life because it is capable of carrying out all the essential functions necessary for an organism's survival. Cells are responsible for processes such as growth, reproduction, metabolism, and response to stimuli.
| 2. How are cells classified? | |
Ans. Cells can be classified into two main types: prokaryotic cells and eukaryotic cells. Prokaryotic cells are simpler in structure, lack a nucleus, and are found in bacteria and archaea. Eukaryotic cells, on the other hand, are more complex, have a nucleus, and are found in plants, animals, fungi, and protists.
| 3. What are the main components of a cell? | |
Ans. Cells are composed of various components, including the cell membrane, cytoplasm, nucleus (in eukaryotic cells), and organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes. These components work together to carry out the cell's functions.
| 4. How do cells obtain energy for their activities? | |
Ans. Cells obtain energy through a process called cellular respiration. In this process, glucose (a type of sugar) is broken down in the presence of oxygen to produce energy-rich molecules called ATP (adenosine triphosphate). ATP is then used by the cell to power various cellular processes.
| 5. Can cells communicate with each other? | |
Ans. Yes, cells can communicate with each other through various mechanisms. One common way is through chemical signals, where cells release signaling molecules (such as hormones or neurotransmitters) that can bind to specific receptors on the target cells. This communication allows cells to coordinate their activities and respond to changes in their environment.
