Why can small nonpolar molecules cross the cell membrane easily while ions cannot?

1. AThe membrane carries a strong positive charge
2. BIons are larger than most membrane proteins

Plants in waterlogged soil take up fewer mineral ions, even when the ions are plentiful. What is the best explanation?

1. AWater dilutes the ions so much that roots cannot detect them
2. BMineral ions only enter by osmosis, and osmosis stops in wet soil
3. CRoot cells lack oxygen, so less ATP is made for active transport
4. DWaterlogged roots carry out more photosynthesis
