Biology Practice: Cell Structure and Functions (Mock Test 4 - Expert/Experimental Logic)
1. In a laboratory experiment, a student places a cell in a high-concentration salt solution. The cell shrinks. This clinical observation is known as:
2. If a researcher uses a chemical to destroy all Ribosomes in a cell, which process will stop first?
3. Why is an Electron Microscope preferred over a Light Microscope for studying the internal structure of Mitochondria?
4. Observation: A cell lacks a nucleus but contains a circular strand of DNA. This cell most logically belongs to:
5. In an experiment using a "Methylene Blue" stain on cheek cells, which part of the cell absorbs the most stain and appears darkest?
6. If the 'Mitochondria' are removed from a cell, the cell will still be able to perform which task for a short time?
7. A student observes a slide with a thick outer boundary and a large central empty space. The nucleus is pushed to the side. This is most likely:
8. What is the logical outcome if the "Selective Permeability" of the cell membrane is lost?
9. "Vital Staining" is a technique used to:
10. Why do human Red Blood Cells (RBCs) lack a nucleus at maturity?
11. A tissue is defined as a group of cells that:
12. In the "Levels of Organization," which sequence is correct?
13. Which experimental setup would best demonstrate the presence of Starch in a leaf cell?
14. If you observe a "Cilia" on the surface of a cell, its most likely expert-level function is:
15. The "Cell Theory" states that:
16. What is the logical reason for "Division of Labour" in multicellular organisms?
17. Which organelle is responsible for the "Autolysis" (self-destruction) of damaged cells during development?
18. A "Vacuole" in a plant cell contains 'Cell Sap' which is a mixture of:
19. If a cell's DNA is damaged, the most immediate "Expert Logic" consequence is:
20. The "Centrioles" are typically found in pairs at right angles to each other within the:
