Submanifolds with parallel second fundamental form are defincd as extrinsic analogue of locally symmetric manifolds [6, 7]. It follovvs that ali of them are locally invariant under the reflection in the normal space of an arbitrary point. These type of submanifolds are also cailed symmetric submamfolds [7 ]. Examples are symmetric jR-spaces. Submanifolds with pointwise planar normal sections (P2-PNS) are introduced in [3, 4, 5 ]. It bas shown tliat spherical submanifolds have P2-PNS property if and only if they must be parellel submanifolds. In [İJ the present author and A. West showed that non-parallel submanifold M has P2-PNS property if and only if It is a hypersurface. In this article we prove that if M is a symmetric R-space then it must be tlıe orbit of the element A such that ad (A))^ = ad{ We also show that the imbeddings of the symmetric K-spaces of tlıe form f: M = Kİ Ko —■ P by f ([fc]) = (k) have P2-PNS.
