 Equivalently, this follows from the fact that CW complexes are preserved under suspensions, and since the sphere is a suspension of {S170}, which is a CW complex {S170|P240}.

 The circle can be given a CW complex structure by associating one $0$-cell and one $1$-cell: Start with $X_0=\{*\}$, then attach a $1$-cell $D^1 = [-1,1]$ by identifying both boundary points with the $0$-cell (define $f_1: \partial D^1 \to X_0$ by $f_1(\pm 1) = *$.)
