What do not go in and out of the cell easily?
Because animal cells lack cell wall, it is present in plant cells.
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
Im pretty sure its carbohydrates
particles that are small and hydrophobic and semipermeable. hydrophobic ions those that are soluble in lipids-- can easily pass through the membrane. In addition, small molecu…les like O2can sneak between the phospholipids of the membrane. On the other hand, hydrophilic molecules (like water and glucose) and ions (such as sodium ions and hydrogen ions) cannot pass directly through the phospholipids of the plasma membrane.
When a cell is being divided (mitosis) the chromosomes condense up so that they can be easily divided.
Gases, water and small polar molecules can easily pass the phospholipid bilayer.
