Hooke had discovered plant cells -- more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term "cells": the boxlike cells of cork reminded him of the cells of a monastery. Hooke also reported seeing similar structures in wood and in other plants.

The chambers were empty because he was looking at dead, dry cells (cork tree bark)

The cell chambers appeared to be empty because they were, in fact, dead and dry cells.
The cork cells were empty because the cells died
