There is a single cell in each dimension except for $d/2$ if the dimension $d$ is even, so this gives what I said. One can replace quadrics by Grassmannians to get similar examples. Of course, many more can be constructed using Damian Roessler's comment. | |

From mine (motivic) point of view, this question should depend on the ground field; does it (for large $n$)? | |
