Read the following statements carefully:
A. | Lipid component of the plasma membrane mainly consists of phosphoglycerides. |
B. | Polar molecules can pass through the lipid bilayer of plasma membrane, therefore they do not require carrier proteins to facilitate their transport. |
C. | The secondary wall is capable of growth and it is formed on the outer side of the cell. |
D. | Quasifluid nature of lipid enables the lateral movement of proteins within the overall lipid bilayer of the plasma membrane. |
E. | Middle lamella glues the different neighboring cells together. |
How many statements are incorrect?
1. Three
2. Five
3. Four
4. Two
In the following diagram, select the part correctly matched with its character or function.
