Answer:
exchange carbon dioxide for oxygen,help with the movement of the blood cells that pump oxygen-rich blood to all cells in the body.
Explanation:
Answer:
The correct answer would be c. The cell has a greater level of structural support.
Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.
They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.
- Lipid bilayer gives the rigidity or shape to the cell.
- It isolates the cell from the sorroundings.
- It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
- Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.
Hence, most appropriate choice would be c. The cell has a greater level of structural support.
