How many statements are correct?
$(A)$ Animal cells contain membrane-bound organelle called centriole which help in cell division.
$(B)$ Lipids are arranged within the plasma membrane with the polar head towards the inner sides and the hydrophobic tails towards the outer side.
$(C)$ The cell wall and middle lamellae may be traversed by plasmodesmata which connect the cytoplasm of neighboring plant cells.
$(D)$ The quasi-fluid nature of lipid enables lateral movement of proteins within the overall bilayer.
