Number of nodal plane(s) present in $s,p_x,p_y,p_z$ are respectively :

Number of nodal plane(s) present in $s,p_x,p_y,p_z$ are respectively 0, 1, 1, 1

We are aware that l for s-orbitals is 0 and l for p-orbitals is 1. P-azimuthal orbital's quantum number is 1. Therefore, there is only one nodal plane in each p-orbital.
