Robert Hooke looked at a thin slice of cork in 1665. He saw many small boxes side by side, and he called them cells. Cork is dead tissue. What exactly did Hooke see, and what was missing?
Need a reminder? The key ideaShow
Hooke named the cell in 1665. He saw the walls of dead cork cells; the living parts had gone.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. What he saw. The cell walls, which stay after the cells die. They looked like the rooms of a honeycomb.
Step 2. What was missing. The living parts: the membrane, the cytoplasm, the nucleus and the other organelles.
Answer: only the empty walls of dead cells.
