they are empty
Cells can appear either filled or empty depending on the presence of organelles, cytoplasm, and other cellular components. In reality, cells are typically filled with various structures and molecules that carry out biological functions.
When Robert Hooke examined a thin cutting of a cork he saw empty spaces enclosed by walls. He called these empty spaces cells.
The stems of woody plants have an outer layer called bark. Bark contains layers of dead cells called cork.Plant cells have a non-living cell wall surrounding the living contents (cytoplasm, nucleus etc). The cells walls of the cork cells contain a waxy material called suberin. This is waterproof and so reduces the loss of water from the stem.However suberin also prevents the cork cells from obtaining water, so the living contents of the cells die and disintegrate, leaving the empty cell walls.So, when Hooke observed cork cells they were empty because they had lost their living contents and all he was seeing were the cell walls.
Cork tissue is formed from the outer layer of the cork oak tree, primarily through the activity of cork cambium, a type of lateral meristem. This cambium produces cork cells, which are dead, hollow cells filled with air, providing insulation and protection. These cells are rich in suberin, a waxy substance that helps prevent water loss and protects against pests and diseases. Over time, layers of cork cells accumulate, forming the characteristic bark of the tree.
The first recorded observation of cork cells was made by English scientist Robert Hooke in 1665. He viewed thin slices of cork through a primitive microscope he had constructed, describing the cells he saw as resembling small, empty rooms or compartments.
they were empty
Robert Hooke's cork cells appeared empty because he was observing dead cell walls. Live cells have contents that can be easily seen under a microscope, but in cork cells, the living material had decayed and left behind only the empty cell walls, making them appear hollow.
Cork is the outer protective tissue of older stems and roots. The mature cork cells become dead and filled with tannis, resins and air.
They are both filled with living material.

Cork cells are bark cells. The bark of every tree consists of dead cells. As dead cells, they are empty. That makes them insulation material. Cork oak trees live in an arid climate. The cork oak bark insulates the tree.

Robert Hooke was the first man to look at cells through his very simple microscope. He observed dead cork cells and described them as cells in a monastary. He called the tiny empty chambers in the cork, cells.
Robert Hooke observed that a slice of cork appeared to be made up of small rectangular compartments, which he called "cells." These cells gave cork a honeycomb-like structure, which led to the discovery of cells as the basic building blocks of living organisms.
The scientist who first observed and named cells in cork was Robert Hooke. In 1665, Hooke used a simple microscope to examine a thin slice of cork and described the empty spaces he saw as "cells" due to their resemblance to small rooms or cellula in Latin.
