Biology Practice: The Cell (Mock Test 4 - Expert Experimental & Clinical Logic)
1. An experimenter removes the Nucleus from an Amoeba using a micro-needle. What is the most likely clinical observation over the next few days?
2. If a cell is treated with a drug that inhibits the function of Mitochondria, which cellular process will be directly halted?
3. In a laboratory setup, a cell is placed in a solution where the osmotic pressure of the solution is equal to the osmotic pressure of the cell sap. This state is called:
4. A patient is diagnosed with a condition where their white blood cells cannot digest captured bacteria. Which organelle is likely malfunctioning?
5. Why do plant cells not burst when kept in distilled water, whereas animal cells (RBCs) do?
6. If the Smooth Endoplasmic Reticulum is extensively developed in a specific cell type, what is the most likely identity of that cell?
7. A plant is kept in the dark for 48 hours to "destarch" it. What is the logical reason for this experiment?
8. Centrioles are inhibited using a specific chemical. What will be the direct consequence on an animal cell culture?
9. Which of the following is a logical conclusion if a cell shows a very high density of Golgi bodies?
10. During the "Iodine Test" for starch, why is a leaf boiled in methylated spirit (alcohol) over a water bath?
11. A mutation in the DNA of the Mitochondria will primarily affect:
12. Why is the "Fluid Mosaic Model" more accurate than earlier models of the cell membrane?
13. In a clinical case of "I-cell disease," enzymes meant for lysosomes are wrongly secreted outside the cell. This points to a failure in:
14. When a raisin (dry grape) is placed in plain water, it swells up. What is the experimental term for this?
15. A cell with an abundance of "Rough ER" is likely to be found in which organ?
16. What experimental observation confirms that a cell is "Turgid"?
17. Which organelle is NOT found in a mature human Red Blood Cell, making more space for Hemoglobin?
18. The "Selectively Permeable" nature of the cell membrane is best demonstrated by its ability to:
19. In the experiment with a thistle funnel and a semi-permeable membrane, the level of liquid rises due to:
20. Which chemical reagent is used to stain the nucleus to make it clearly visible under a microscope?
