Biology Practice: Cell - The Unit of Life (Mock Test 3 - Advanced: Processes, Mechanisms & Why/How)
1. Why is the Plasma Membrane described as "Selectively Permeable" rather than just permeable?
2. How do Mitochondria generate energy in the form of ATP?
3. What is the mechanism behind the "Suicidal" action of Lysosomes?
4. Why do plant cells require a large central vacuole compared to animal cells?
5. How does the "Surface Area to Volume Ratio" affect the functioning of a cell?
6. What is the role of "mRNA" in the process of protein synthesis within a cell?
7. Why are Chloroplasts described as "Solar Collectors"?
8. What mechanism allows the "Rough ER" to process proteins differently than the "Smooth ER"?
9. How does the "Fluid Mosaic" nature of the membrane allow for "Endocytosis"?
10. Why is the "Nucleus" often called the 'Director' of the cell?
11. What would happen to an animal cell if its "Lysosomes" stopped functioning?
12. How do "Centrioles" facilitate the process of cell division in animal cells?
13. Why is "Protoplasm" called the 'Physical Basis of Life'?
14. What is the logic behind the "Double Membrane" structure of Mitochondria and Chloroplasts?
15. How does a cell "know" how to build a specific protein?
16. Why is the "Smooth ER" abundant in liver cells?
17. What is the primary cause of "Turgidity" in plant cells?
18. Why are "Chromosomes" only visible during cell division?
19. How does "Cytoplasmic Streaming" benefit a large plant cell?
20. What is the fundamental difference between "Prokaryotic" and "Eukaryotic" genetic material organization?
