The correct Answer is:
To determine which statements are false, let's analyze each option one by one: ### Step-by-Step Solution: 1. **Option (a)**: "Most cells are tiny with volume range of `1-100 nm^(3)`." - **Analysis**: This statement is false. While most cells are indeed small, their volume typically ranges from micrometers (µm) to nanometers (nm), with many cells being larger than 100 nm³. For example, a typical cell volume can be in the range of 1,000 to 1,000,000 nm³ (or 1 to 1,000 µm³). - **Conclusion**: This statement is **false**. 2. **Option (b)**: "Some cells have microvilli to increase the absorptive surface area." - **Analysis**: This statement is true. Microvilli are small, finger-like projections found on the surface of some cells (e.g., intestinal epithelial cells) that increase the surface area for absorption. - **Conclusion**: This statement is **true**. 3. **Option (c)**: "All cells arise from pre-existing cells." - **Analysis**: This statement is true and is a fundamental principle of cell theory. It states that new cells are produced from existing cells through cell division. - **Conclusion**: This statement is **true**. 4. **Option (d)**: "In plants, translocation of solutes is performed by xylem vessels and tracheids." - **Analysis**: This statement is false. Translocation refers to the transport of organic nutrients (like sugars) and is primarily carried out by phloem, not xylem. Xylem is responsible for the transport of water and minerals. - **Conclusion**: This statement is **false**. 5. **Option (e)**: "According to cell theory, all cells arise from abiotic material." - **Analysis**: This statement is false. The cell theory states that all cells arise from pre-existing cells, not from abiotic (non-living) material. - **Conclusion**: This statement is **false**. ### Summary of Findings: - **False Statements**: (a), (d), and (e). - **True Statements**: (b) and (c). ### Final Answer: The false statements are (a), (d), and (e).
