An important characteristic of the plant cell wall is b) it is rigid.
This rigidity provides structural support and determines the shape of the plant cell.
When it comes to the phospholipid bilayer of the cell membrane, b. there is a water-fearing side inside the cell is the correct statement. The phospholipid bilayer consists of a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophobic tails face inward, shielded from water, whereas the hydrophilic heads face outward towards the water inside and outside the cell.
